Answer:
c?
Explanation:
Large piles of sand that move across the desert floor is an example of wind erosion. Thus, option B is correct.
What is the wind erosion?When strong wind passes over shadow topsoil that have been heavily grazed during drought periods, meaningful wind erosion occurs. Wind erosion is a natural process as well.
Understanding wind erosion is critical because it lays the groundwork for developing proper and efficient land management and subsidence control processes. It encourages the use of environmentally responsible management practises in the grazing and cropping industries to control wind erosion.
Therefore, option B is correct, that wind erosion is exemplified by large sand piles that move across the desert floor.

Explanation:
Which of the following is the best explanation of the fact that ag. production of floodplains is often relatively high?a. on flood plains soils tend to be nutrient-rich and fertileb. on floodplains high water tables make irrigation rich and fertilec. periodic flooding leaches toxic pollutants into floodplain soild. periodic flooding prevents the PH of floodplain soils from becoming too high
Answer:
a. on flood plains soils tend to be nutrient-rich and fertile
Explanation:
A floodplain is an area of the land that is adjacent to the river or steam and that stretches the channels of the base to the enclosing valleys and the soi, usually, consist of clays and silt and sands and thus the meandering water erodes the downstream of the deposition of the silt behind the lands. It also represents the and by the fluvial terraces and in terms f the ecology they are diverse and most fertile lands ad thence the wetlands and the riparian zone are those of the soil as an intermediate supply of nutrient and thus are valuable for the agriculture.Why is Neptune denser than Saturn?
A) It has a different composition than Saturn, including a higher proportion of hydrogen compounds and rocks.
B) It has a greater proportion of hydrogen than Saturn.
C) The extra mass of Neptune compresses its interior to a greater extent than that of Saturn.
D) Its hydrogen is molecular, whereas Saturn's hydrogen is atomic.
E) It is notdenser than Saturn.
Answer:
A) It has a different composition than Saturn, including a higher proportion of hydrogen compounds and rocks.
Neptune is denser than Saturn due to its different composition, which includes a higher proportion of hydrogen compounds and rocks.
Explanation:The correct answer is A) It has a different composition than Saturn, including a higher proportion of hydrogen compounds and rocks.
Neptune is denser than Saturn because it has a greater proportion of heavier elements, such as rocks and hydrogen compounds, in its composition. Saturn, on the other hand, has a greater proportion of lighter gases, such as hydrogen and helium.
This difference in composition contributes to Neptune's greater density compared to Saturn.

Why is the Mekong River so important to Southeast Asia?
Answer:
More than 70 million people live in the Mekong river basin, and they rely on the river for drinking water, food, irrigation, hydropower, transportation and commerce. The Mekong and its wildlife have strong cultural significance too.
The Mekong River is Southeast Asia's lifeblood. It provides water, food, and transportation to millions of people in the region. The river also supports a varied ecology, which includes several endangered species.
Here are some of the reasons why Southeast Asia values the Mekong River:
Water: The Mekong River is Southeast Asia's lifeblood. Millions of people in the region rely on it for drinking water, irrigation water, and industrial water. The river also aids in climate regulation, averting droughts and floods.Food: The Mekong River is home to the greatest inland fishery in the world. It generates an estimated 4.5 million metric tons of fish each year, providing a critical source of nourishment for the region's residents.Transportation: In Southeast Asia, the Mekong River serves as a major transportation corridor for both people and cargo. It is used for transporting people, conveying products, and fishing.Hence, Southeast Asia relies heavily on the Mekong River. It is critical to the economy, ecology, and culture of the region.

In the video, you learned about the evolution of cinder cones and basaltic lava flows. These features are formed by volcanic eruptions when magma is erupted at the surface of the Earth. The photo in Part A shows Red Hill, located in central New Mexico. This site shows a distinct red cinder cone and adjacent lava flow. The basaltic lava flow has been broken up by processes of weathering and erosion.
A cinder cone, also known as a scoria cone, is a sharply curved mound formed around a volcanic vent by loose pyroclastic debris, such as volcanic ash, scoria, or volcanic clinkers.
Lava flow
formed by effusive eruptionsCinder cone
Formed by explosive eruptionsBoth features
Basaltic material is more commonTens to hundreds of meters can be found on the top of cinder cones, which frequently feature a bowl-shaped crater. As opposed to spatter cones, which are made of agglomerated volcanic bombs, they are made of loose pyroclastic debris, such as cinder or scoria.
Lava flow
A lava flow is the result of geothermal energy erupting from the ground at temperatures between 700 and 1200 °C in the form of lavas or magma at the planetary crust.Cinder cone
The silicate, feldspar, olivine, mica, quartz, and other materials make up lava. Pahoehoe lava is a smooth, continuous form of lava with a ropy, billowy, or undulating surface that contributes to its low viscosity.Therefore, A cinder cone, also known as a scoria cone, is a sharply curved mound formed around a volcanic vent by loose pyroclastic debris, such as volcanic ash, scoria, or volcanic clinkers.

The highest recorded temperature on Earth was in a ______________________
a. low-latitude, high elevation desert in Mexico.
b. tropical rain forest in Brazil.
c. high-latitude, high-elevation desert in Mongolia.
d. low-latitude, low-elevation desert in Libya
Answer:
d. low-latitude, low-elevation desert in Libya
Explanation:
From 1922 until 2012, the WMO record for the highest official temperature on Earth was 57.8 °C (136.0 °F), registered on September 13, 1922 in 'Aziziya, Libya.
The highest recorded temperature on Earth was in a low-latitude, low-elevation desert in Libya. Low latitudes have high temperatures due to direct sunlight, contributing to high temperatures especially in deserts like those in North Africa.
The highest recorded temperature on Earth was in a low-latitude, low-elevation desert in Libya. Low latitudes, which are near the equator, generally have high temperatures because the sun's rays hit these areas more directly. This solar intensity, coupled with the low elevation that typically traps more heat due to denser atmosphere at lower altitudes, leads to high temperatures, particularly in desert regions.
Deserts are defined by their low precipitation and because of the sparse cloud cover, there is more solar energy absorption during the day, leading to extreme temperatures. The subtropical deserts, such as those in North Africa including the Grand Erg Desert, can experience very high temperatures. At low elevations in these deserts, the lack of moisture and minimal cloud cover contribute to the recording of some of the highest temperatures on Earth.
