Answer:
Plantation agriculture.
Explanation:
The parts of the east and southeast Asia lies in the region of china and that of Indian and the islands of the Indonesia these communities cultivate and domesticate crops that have commercial value and the crops include the paddy cultivation and the cultivation of sugarcane and other plantation crops. Thus this system of the agriculture in the south and east Asia is that of the Japanese know or the cultivation of the rice and the millets as these cities are the most populated nations in Asia and thus have rice as the major crops that are grown on a large scale to meet the growing demands and the needs of the growing population. But various problems are related to this type pf the cultivation as the environmental problems of the agricultural runoff and the runoff system that is influenced by the presence of the pesticides and the other toxic chemicals that harm and degrade the quality and the quantity of the soil and the water system and thus this impacts the environment to a greater extent.Final answer:
Intensive subsistence tillage in South and East Asia is related to population growth concerns, especially in regions with abundant water. Despite agricultural advances like the Green Revolution, high rates of child malnutrition persist. Rice cultivation dominates in areas with ample water, while wheat production is common in drier regions.
Explanation:
Intensive subsistence tillage is the distinctive type of agriculture practiced in the population concentrations of East and South Asia. This type of agriculture relates to concerns over the world's growing population and environmental problems as it employs millions, feeds billions, and dominates in regions with long growing seasons and abundant water, such as parts of China, India, and southeast Asia.
Population growth remains a major concern in South Asia, challenging economic systems and depleting natural resources. Despite advances like the Green Revolution, high rates of child malnutrition persist, especially in India.

Identify the true statement.
a. Strip mining can be done economically down to a depth of about 1 km.
b. Anthracite coal develops at depth along mountain belt borders, where temperatures reach 600°C.
c. Underground coal mining is dangerous because of possible tunnel collapse and possible methane gas explosions.
d. Coal began to form on the Earth soon afterlife evolved in the Precambrian.
Answer:
Option (C)
Explanation:
Coal is a sedimentary rock that forms due to the accumulation of dead matters of plants, trees, and converting it into coal over millions of years.
This coal is extracted from the earth in two ways-
Opencast mining- Here, in order to extract the coal, large strips of land are being excavated. Here, the construction of the tunnel is not required. It is comparatively safe and affects the environment in both long as well as short term. Underground mining- Here, the excavations and sub-surface tunnels are made in order to extract the required materials from a certain depth. This method is risky because the underground tunnels and the roof rocks can get the collapse and there may occur the methane gas explosion, and causes a fire, which is why it is not very safe to carry out underground mining.Thus, the correct answer is option (C)- which is true.

Which of the volcanoes below is least in need of monitoring?
a. Mount Rainier, Washingtonb. Kauai, Hawaii
c. Kilauea, Hawaii
d. Mount Fuji/Fujiyama, Japan
Kauai in Hawaii, with its dormant volcanoes, is the least in need of advanced volcano monitoring systems compared to the actively threatening volcanoes Mount Rainier, Kilauea, and Mount Fuji.
Explanation:Among the volcanoes listed, Kauai in Hawaii is the least in need of a state-of-the-art volcano monitoring system. Kauai is home to dormant volcanoes that are not currently showing signs of activity. In contrast, Mount Rainier is an active stratovolcano with a significant risk of future eruptions, Kilauea is among the world’s most active volcanoes, and Mount Fuji in Japan is an active stratovolcano and also a significant risk due to its proximity to populated areas. Given that Kauai's volcanic threat is minimal compared to the others, it would be deemed the least in priority for state-of-the-art monitoring.
Antarctica receives more solar radiation than does any other place on Earth, yet the temperatures are so cold and the ice cap is reflective, so that little polar ice melts during the summer; otherwise, the water levels of the oceans would rise 250 feet and engulf most of the world’s great cities.
(A) is reflective, so that little polar ice melts during the summer; otherwise,
(B) is so reflective that little of the polar ice melts during the summer; were it to do so,
(C) so reflective that little polar ice melts during the summer, or else
(D) reflective, so that little of the polar ice melts during the summer, or
(E) reflects so that little of the polar ice melts during the summer; if it did
Answer:
Option (B)
Explanation:
From the given sentence, the use of the parallelism in the wording has to be taken in consideration. So, as -are so is used in the word -cold, likewise, the word -is so will also be used right before reflective. Then again, as the sentence continues, the phrase "-were it to do so" will provide the consequence of the melting of the ice, which is the first component of the sentence.
Thus, the correct answer is option (B).
According to the USDA, soil surveys show more than __% of natural topsails in North America has been lost since farming began in the U.S.
Answer:
30%
Explanation:
Every consecutive year the loss of topsoil becomes a serious issue for the farmer and policymaker. The reason behind the continuous loss of topsoil is when the upper layer of soil left fallow and exposed to heavy rains and winds. which takes the upper surface with them.
The practice like grazing of field and growing of crop on steeper slopes and continuous practice like crop rotation are the main reason behind the soil erosion.
As the country is moving toward the fast technology phase, practice of securing land to prevent it from erosion is lacking. The other reason behind the fast removal of topsoil is the use of modern technology to grow a crop.

In which of the following environments would you expect lithogenous sediment to be the dominant sediment type?
Answer: continental margins, muddy lagoons, sandy beaches, deep oceans.
Explanation:
Lithogenous sediments are sediments whose mineral grains are formed during the weathering of rocks, this sediments are transported by agents such as force of gravity, wind action, running water and movement of ice.
Lithogenous sediments are the most abundant sediments on the earth crust, example includes glacial marine sediments, abyssal clays etc. These sediments are composed of quartz, clay, and other rock fragments. They are found widely distributed along the continental margins, deep oceans, sandy beaches, muddy lagoons, etc.
Lithogenous or terrigenous sediments are derived from the weathering of continental rocks. As such, they dominate in areas close to land, including beaches, deltas, and nearshore areas. Factors like climate, current patterns, and bedrock type can influence their distribution.
Explanation:Lithogenous sediment, also known as terrigenous sediment, typically originates from the physical and chemical weathering of continental rocks. As such, you would expect to find lithogenous sediment as the dominant sediment type in locations close to land.
This includes, but is not limited to, beaches, deltas, and nearshore areas where rivers flow into the sea. Sediment carried by wind, such as in deserts, can also be classified as lithogenous. However, one must also note that the distribution of various sediment types in different environments is affected by factors like climate, current patterns, and the nature of the local bedrock.

If the plane of the Moon's orbit were the same as the ecliptic (the plane of Earth's orbit), we would have ____ eclipses (counting both solar and lunar) each month.
If the Moon's orbital plane were the same as the ecliptic, we would have two eclipses each month - one solar and one lunar. In reality, the inclination of the Moon's orbit prevents this, leading to approximately two eclipses happening during 'eclipse seasons' every six months.
If the plane of the Moon's orbit were the same as the ecliptic, we would have two eclipses each month. This is because under these circumstances, every new moon would align with the Sun and the Earth to cause a solar eclipse, and every full moon would align with the Earth and the Sun to cause a lunar eclipse. However, in reality, the Moon's orbit is inclined about 5° to the ecliptic, which prevents this monthly occurrence of eclipses. Instead, we have 'eclipse seasons' when the paths cross, typically resulting in two eclipse opportunities (one solar and one lunar) roughly every six months.

Final answer:
The A) thermosphere is the layer of the atmosphere that contains charged gas molecules that glow and produce light when hit by solar energy, leading to glowing gases such as the northern lights.
Explanation:
The layer of the atmosphere that contains charged gas molecules that glow and produce light when hit by solar energy, leading to glowing gases such as the northern lights, is the thermosphere. The thermosphere starts just above the mesosphere and extends to 600 kilometers (372 miles) high. It is in this layer that auroras occur due to the interaction between solar energy and charged particles in the ionosphere.
Thus, it is a layer of Earth's atmosphere characterized by its high temperatures and low density. The thermosphere is where solar activity strongly influences the temperature, causing it to rise significantly. Electrified oxygen components in the mesosphere layers of the atmosphere burn and produce electricity whenever solar radiation touches them, releasing gases that are visible to the na-ked eye.

Thanks for your question! Feel free to ask more!
Final answer:
The correct answer is 'A. pentatonic and tritonic'. The pentatonic scale is a five-note scale that is heavily used in traditional music, while tritonic scales with three notes are less common but still present in various music traditions.
Explanation:
Common scales used in African, Far Eastern, and Native American music are pentatonic and tritonic scales. The pentatonic scale is a five-note scale used widely in traditional music across various cultures. A common version of the major pentatonic scale is derived from the major scale but without the 4th or 7th pitches, while one of the popular minor pentatonic scales is similar to the minor scale but also omits these pitches. Tritonic scales, which use three pitches, are less common but also appear in some traditional musical contexts.
Instruments such as the Japanese koto and shakuhachi often utilize pentatonic scales. These scales enable musicians to create music that is beautiful and harmonious without the complexity of additional pitches found in heptatonic (seven-note) scales. The simplicity of the pentatonic scale can be seen in children's songs, early American folk music, and the blues, where the scale contributes to the music's distinct sound.
Describe how the idea of archaeological context affects how an archaeological site is excavated. What must archaeologists do in order to preserve context?
Answer:
Place where an artifact is found is known as archaeological context
Explanation:
The idea of archaeological context is concerned with the site of artifact presence. The soil, the site type, the layer the artifact was found are all components of the context. To preserve this context, the site must be monitored and put under consistent surveillance. The records consisting of artifacts, biofacts, architecture and cultural information must be registered to detail for future access and assessment from time to time. The cultural and site information must be protected from loss and deterioration. Protective shelters around site where artifacts are found are needed to preserve such artifacts. Reconstruction and reburial of artifacts found may also be needed to preserve them.
