Science
How does rain affect earth.
Rain fall causes erosion when it hits earth. This is called splash erosion.
What is biological weathering?
Weathering caused by humans or animals.
What is erosion?
The process of eroding or being eroded by wind, water, or other natural agents.
What is hydrolysis?
How do humans affect erosion?
Humans use construction, gardening and mining which disturbs earth.
How does wind affect erosion?
Wind generally causes erosion by deflation and/or abrasion. Wind breaks are often planted by farmers to reduce wind erosion.
What is rusting.
To be affected with rust.
What is frost wedging?
The splitting or break-up of rock by the pressure of water freezing in cracks.
What is abrasion?
The process of scraping or wearing something away.
What is a chemical weathering?
Erosion caused by chemical reactions.
What is a landscape? What happens to landscapes when erosion occurs?
Visible features of an area of countryside or land.
Weathering and erosion constantly change the rocky landscape of Earth.
What is temperature. How does it affect weathering
The degree or intensity of heat.
As rocks expand and contract, the heat creates a physical weathering process where the rock splits apart into fragments.
What is the Geosphere? How is it affected by erosion?
The rocky surface of earth.
The erosion of rocks, a major part of the rock cycle and change in the Geosphere over time.
How do waves affect erosion?
Waves erode sediments from cliffs and shorelines.
What is ice? And how does it affect earth?
Frozen water. Which affects erosion through frost wedging.
What is a stream? And how does it affect earth?
A small, narrow river. Flowing streams pick up and transport weathered materials by eroding sediments from their banks.
What is deposition?
Sediments, soil and rocks are added to a land form or landmass.
What is clay formation?
The chemical decomposition of feldspar.
What is convection?
The movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.
What is Mechanical weathering?
Erosion caused by mechanical reactions.
