Which factor does not play a role in both weathering and erosion?
Chemical composition of the rock does not play a role in erosion, as erosion is primarily driven by forces like water, wind, and ice that physically wear down and transport rock particles. In weathering, factors such as temperature, moisture, and type of vegetation can contribute to the breakdown of rock material.
What role does physical weathering play in the formation process of sandstone?
Physical weathering contributes to the breakdown of rocks into smaller fragments, which eventually accumulate and form sand. These sand grains are then cemented together over time to create sandstone. Examples of physical weathering processes that contribute to sandstone formation include abrasion from wind or water, freeze-thaw cycles, and thermal expansion and contraction.
What must be present for weathering to occur?
Weathering occurs due to the breakdown of rocks and minerals on the Earth's surface. It requires the presence of water, air (oxygen), and sometimes living organisms to aid in the chemical or physical breakdown processes. Temperature variations and mechanical forces, such as wind or ice, also play a role in weathering.
Are valleys formed by weathering and erosion?
Yes, valleys are primarily formed by a combination of weathering and erosion processes over time. Weathering breaks down rocks into smaller particles, while erosion transports these particles away, often carving out valleys in the landscape. Factors such as water, wind, ice, and gravity all play a role in shaping valleys through weathering and erosion.
Living things play no role in physical or chemical weathering?
Actually, living organisms can play a significant role in both physical and chemical weathering processes. For example, tree roots can break apart rocks through physical weathering, while certain microorganisms can produce acids that contribute to chemical weathering. In general, the presence of living organisms can speed up the weathering of rocks and minerals.
What role does wind and water play for sedimentary rocks?
weathering and erosion helps to build sedimentary layers then sedimentary rocks
What role does weathering play?
Breaks down rocks

Can the American flag fade in the winter?
Yes, but wind plays the most damaging role in the weathering of a flown flag.

How does elevation change weathering?
The higher in elevation the more wind and rain there is. weathering happens by wind and water.
Is mechanical weathering caused by?
Gravity plays a small part in mechanical weathering but temperature, weather, animals, plants, water and wind play much bigger parts.
Does the sun play a role in weathering?
Yes, the sun plays a role in weathering through a process called thermal weathering. This occurs when rocks expand and contract due to temperature changes caused by sunlight, leading to their breakdown over time.
What do weathering and ersion have in common?
Weathering and erosion are both processes that lead to the breakdown and transport of rocks and sediments. Weathering breaks down rocks into smaller pieces, while erosion involves the removal and transport of these pieces by natural forces like wind, water, or ice. Together, they play a key role in shaping the Earth's surface over time.
