How do wind and water break down rocks?
Chemical weathering changes the molecular structure of rocks and soil. For instance, carbon dioxide from the air or soil sometimes combines with water in a process called carbonation. This produces a weak acid, called carbonic acid, that can dissolve rock.
Which process is faster weathering or erosion Why?
I think erosion is fast process. in weathering it takes a lot of time to crush the Rock.
How do wind causes erosion?
Wind cannot carry as large particles as flowing water, but easily pick ups dry particles of soil, sand and dust and carries them away. Wind generally causes erosion by deflation and/or abrasion. Wind breaks are often planted by farmers to reduce wind erosion.
What is the role of water and wind in erosion and deposition?
Moving water does much of the work of erosion that shapes the land surface of our Earth. Wind also flows over the Earth’s surface, sometimes carrying particles long distances before they are deposited. Wind blows from areas of high pressure to areas of lower pressure.
How does temperature differences make the Wind Blow?
How would temperature differences make the wind blow? The gases that make up our atmosphere do interesting things as the temperatures change. When gases warm up, the atoms and molecules move faster, spread out, and rise. That’s why steam coming off a pot of boiling water always goes upward.
Why does water move up and down in the ocean?
Water moves up and down in the ocean due to temperature differences, just as it does in the air. Warm water will rise towards the surface and colder; denser water will sink to lower ocean depths.
Why does wind move from high pressure to low pressure?
Because warm air rises, it leaves behind an area of low pressure behind it. Here comes the wind! Now we’re getting to the part where wind happens. Gases move from high-pressure areas to low-pressure areas.
How are wind currents related to the atmosphere?
The colder air is denser and sinks to Earth’s surface, causing it to drag faster than aloft warm air in the atmosphere. The resulting rotations in the atmosphere, known as the Coriolis effect, create wind currents. Like the atmosphere, ocean water is also dragged counterclockwise while Earth rotates.
