Weathering is the breaking down of rock into smaller and smaller particles. Weathering processes include frost wedging, acid rain dissolution, root growth, wind particle abrasion, heat expansion cracking, hydraulic fracture, and rock tumbling in rivers and streams.
Erosion is the movement of weathered material from one place to another place through the agents of erosion: wind, water, ice, and gravity.

What are the 4 forces that cause weathering?
The four forces that cause weathering are mechanical weathering (breaking down of rocks into smaller pieces), chemical weathering (alteration of rock composition through chemical reactions), biological weathering (breaking down of rocks by living organisms), and physical weathering (breaking down of rocks through physical processes like temperature changes and abrasion).
Is water a cause of physical weathering or chemical weathering?
It is a cause of both.
What are 2 factors that effect the shape of land?
Two factors that affect the shape of land are erosion, which wears away land over time through processes like wind and water, and tectonic forces, such as plate movement and volcanic activity, which can cause land to shift and change in elevation.
What is a natural forces which affect the land?
Natural forces that affect the land include erosion (caused by water, wind, or ice), weathering (breaking down of rock due to exposure to elements), and tectonic activity (such as earthquakes, volcanoes, and mountain building). These forces shape the Earth's surface over time.
What are forces that cause the Earths surface to constantly change and what are their effects on the planet?
Forces like plate tectonics, erosion, and weathering constantly shape Earth's surface. Plate tectonics cause earthquakes and volcanic eruptions, shaping the planet's landforms. Erosion by wind and water can carve out valleys and canyons, while weathering breaks down rocks into sediment, contributing to the formation of soils.
Which is a cause of mechanical weathering?
physical forces
What are three related forces that cause weathering?
Three related forces that cause weathering are physical weathering (such as freeze-thaw cycles and abrasion), chemical weathering (such as oxidation and hydrolysis), and biological weathering (such as root growth and burrowing animals breaking down rocks).
What factors can cause exposed land to change?
Weathering and erosion cause exposed land to change.
What are the forces that cause mechanical weathering?
Some forces that cause mechanical weathering include temperature changes (freeze-thaw cycles), pressure changes, and abrasion by wind or water. These forces can break down rocks into smaller pieces over time.
What forces can cause land change over time?
Land change over time can be caused by various forces such as weathering, erosion from wind and water, volcanic activity, plate tectonics, and human activities like deforestation and urbanization. These forces can shape the landscape by altering the landforms, soil composition, and vegetation cover.
What are the 4 forces that cause weathering?
The four forces that cause weathering are mechanical weathering (breaking down of rocks into smaller pieces), chemical weathering (alteration of rock composition through chemical reactions), biological weathering (breaking down of rocks by living organisms), and physical weathering (breaking down of rocks through physical processes like temperature changes and abrasion).
Why is the surface of the earth not totally level after all of this weathering?
a) constructive forces build up the land at the same time
What unnatural forces cause weathering and erosion?
Unnatural forces that cause weathering and erosion include activities like deforestation, mining, construction, and urbanization. These activities can disrupt natural processes and accelerate erosion by removing vegetation cover, compacting soil, or altering natural drainage patterns. Pollution from industrial and agricultural activities can also contribute to accelerated weathering and erosion.
What are the forces that cause weathering?
Weathering is primarily caused by three main forces: mechanical weathering, chemical weathering, and biological weathering. Mechanical weathering occurs when rocks are broken down into smaller pieces through physical processes such as freezing and thawing. Chemical weathering involves the breakdown of rocks through chemical reactions, such as oxidation and hydrolysis. Biological weathering is caused by living organisms, which can break down rocks by their growth, burrowing, or through chemical processes.
What is a cause of mechanical weathering A physical forces B rainwater C natural acids D sunlight?
A. Physical forces such as frost action, root wedging, and abrasion are causes of mechanical weathering. These forces break down rocks into smaller pieces by physically altering their structure without changing their chemical composition.
How do forces on the earths surface affect the shape of the land?
Forces such as erosion, weathering, and tectonic movement can cause changes in the shape of the land. Erosion by water, wind, or ice can wear down the land surface, while weathering breaks down rocks. Tectonic forces, like plate movement, can lead to the creation of mountains, valleys, and other land formations.
Do acids cause mechanical weathering?
No, acids cause chemical weathering.
