Solar ultraviolet radiation breaks chemical bonds, degrading material. There is also mechanical wear from thermal expansion and contraction caused by the diurnal cycle. At night material cools and contracts, during the day it warms and expands. Over time this causes rock to crack and break.
Faster yet is the action of moisture. Water seeping into cracks which subsequently freezes widens gaps, pushing rock down slope. Rain and flooding carries this material downstream, eventually dumping it into the ocean. Mountains are gradually weathered down by wind born material, rain and snow.
These processes result in erosial features such as sand bars, gravel beds, gullies, and canyons. Young canyons are typically fairly steep and straight. Older canyons will be broad, and the rivers flowing through them eventually meander, creating big loops known as "ox bows." Solitary rock formations on a broad flood plain or "peneplain" that survive long term riparian activity are known as "monadnocks."

How does weathering and erosion shape earths surface?
Weathering breaks down rocks into smaller pieces, while erosion transports these pieces to new locations. Over time, these processes can create features like valleys, canyons, and coastlines, shaping the Earth's surface.
Processes that break down rock at earths surface?
Weathering and erosion processes break down rock at Earth's surface. Weathering involves physical breakdown (mechanical weathering) and chemical breakdown (chemical weathering) of rocks, while erosion involves the transportation of the broken-down rock particles by agents like water, wind, or ice. Over time, these processes shape the Earth's surface and contribute to the formation of landforms.
Buried rock is exposed at earths surface by the combination of which two processes?
The combination of weathering and erosion exposes buried rock at the Earth's surface. Weathering breaks down the rock into smaller pieces, while erosion transports these pieces away, eventually revealing the rock at the surface.
Does weathering and erosion affects all rocks on the earths surface?
Yes, weathering and erosion affect all rocks on Earth's surface to some extent. Weathering breaks down rock into smaller pieces, while erosion transports these pieces to new locations. These processes are constant and can shape the landscape over time.
What 3 processes act together to wear down and build up earths surface?
Erosion, weathering, and deposition are the three primary processes that work together to wear down and build up Earth's surface. Erosion involves the movement of sediment and rock particles by natural forces. Weathering breaks down rocks into smaller pieces. Deposition occurs when eroded material is deposited in new locations. Together, these processes shape Earth's landscapes over time.

What are the process that cause earths surface to wear down?
Weathering and erosion
What is processes that break down rock at earths surface?
Denudational processes, which includes, weathering, erosion, deformation, and exfoliation. Mass movement also plays a great role in changing the earths surface.
What are the processes that break down rock at earths surface?
Weathering and erosion are the processes that break down rock at the Earth's surface. Weathering includes physical, chemical, and biological processes that break down rocks into smaller pieces, while erosion involves the movement of these weathered materials by water, wind, ice, or gravity.

What is a physical process that mainly occurs above the earths surface?
Erosion, weathering

How does weathering and erosion effect earths surface?
well, lets see. weathering and ersion are both destructive fources, there for, they destroy Earth's surface.
