What is the definition of erosion?
Answer: Hiya!
The definition of erosion is "the process of eroding or being eroded by wind, water, or other natural agents."
Explanation:
Erosion is a process where natural forces like water, wind, ice, and gravity transport rocks and soil.

Erosion refers to the process of wearing away or removal of material from the Earth's surface, primarily through the action of natural agents such as water, wind, ice, or gravity. It involves the transportation and deposition of sediment and soil from one location to another.
Erosion occurs when the forces of these agents exceed the resistance of the surface materials, leading to the gradual or rapid removal of soil, rocks, or other geological features. The eroded materials are then transported and may be deposited in different areas, contributing to the reshaping of landscapes over time.
Erosion can have both natural and human-induced causes. Natural erosion processes, such as water erosion caused by rivers or wind erosion in arid regions, are part of the Earth's natural geological cycle. However, human activities, such as deforestation, overgrazing, construction, and improper land management practices, can accelerate erosion rates and cause significant environmental damage.
Overall, erosion plays a crucial role in shaping the Earth's surface, creating landforms like valleys, canyons, deltas, and beaches. Understanding erosion processes is essential for managing and conserving natural resources and mitigating the negative impacts of erosion on ecosystems and human activities.

In 2001, a population of 2,500 poison dart frogs lived in the Amazon rain forest. Due to increased deforestation, the population dwindled to 25 frogs in 2019. New government regulations were enacted in 2022, successfully putting an end to the deforestation of the Amazon rain forest.

Why is the rainfall pattern different on the Mountains of Kohala and Mauna Kea?
The Mountains of Kohala and Mauna Kea are located on the Big Island of Hawaii and have different rainfall patterns due to their geographic location and topography.
Where is the location of Mauna Kea?Kohala is located on the northern part of the island and is the oldest volcano in the Big Island, shielded from the prevailing trade winds by the taller volcanoes of Mauna Kea and Mauna Loa.
The moisture carried by the trade winds falls on the eastern side, and much less falls on the western side. Kohala, being located on the leeward side, receives less rainfall and is drier than the windward side.
Mauna Kea is located to the south of Kohala. It is also located on the windward side of the island. Therefore, it receives more rainfall due to the moisture carried by the trade winds. As the air rises over the mountain, it results in more precipitation on the windward side.
Therefore, the rainfall pattern is different on the Mountains of Kohala and Mauna Kea due to their location relative to the trade winds and the topography of the island.

Which of these statements about ocean waves is true?
A. Water molecules move in a circular path but basically stay in one place.
B. Water molecules move sideways perpendicular to the wind.
C. Water molecules move forward in the direction of the wind.
D. Water molecules in a wave move only up and down.
The statement that is true about the ocean waves is that Water molecules move forward in the direction of the wind.
Option C
What are ocean waves?The basic definition of the waves is that a wave is a disturbance along a medium which transfers energy. In the case of the ocean, we know that the energy is transferred as the water is in motion from one point to the other.
The movement of the waves of the ocean is always driven by the wind that is blowing in the sea and as such the waves that is generated in the sea would move in the direction of the wind.

In North Carolina, demand for fresh water has increased dramatically. One of the main reasons for this is increased water use for agriculture. Respond to the following in 3–5 sentences:
Relate one effect of agricultural water use on North Carolina's river basins.
Relate one conservation strategy that would reduce the effect of agricultural practices on water quality
Agriculture is an activity that requires a lot of fresh water.
This is because agricultural crops need large amounts of water to grow and remain productive. In a situation of large-scale agricultural production, this need for water is even greater, causing producers to use large quantities of water that is necessary for the consumption of the population.Give the detailed explanation?In order to conserve fresh water and keep it at high quality levels to be used both in agriculture and for human consumption, it is necessary that agricultural producers allow the maintenance of riparian forests, use more biodegradable pesticides or with low impact on nature and pay attention to irrigation equipment to avoid waste.
In addition, many producers waste water and pollute it with an excess of pesticides and deforestation.
