Which factor has the greatest influence ie weathering rate of Earth's surface bedrock?
The climate is the factor that has the greatest influence on the weathering rate of Earth's surface bedrock. Temperature and precipitation variations determine the intensity and type of weathering processes that shape the landscape over time.
Which factor has the greatest influence on the weathering rate of Earth's surface bedrock?
The presence of water is the factor with the greatest influence on the weathering rate of Earth's surface bedrock. Water can seep into cracks in the bedrock, freeze, expand, and cause physical weathering. It also participates in chemical weathering processes that break down the minerals in the bedrock.
How did weathering erosion and deposition create sinkholes?
Weathering weakens the bedrock beneath the surface, making it susceptible to erosion. Water seeps into the cracks in the bedrock, dissolving it and creating underground caverns. Eventually, the roof of the cavern collapses due to gravity, creating a sinkhole.
Which long-term atmospheric changes would increase the rate of chemical weathering of surface bedrock?
Increased levels of carbon dioxide in the atmosphere can lead to more carbonic acid in rainwater, which accelerates chemical weathering of surface bedrock. Additionally, higher temperatures and increased precipitation can also enhance chemical weathering processes by speeding up chemical reactions and erosion rates.
Does Chemical weathering in bedrock below the land surface often begins along joints and sheeting fractures?
Yes, chemical weathering in bedrock often starts along joints and sheeting fractures because these areas provide pathways for water and other agents to penetrate the rock, accelerating the weathering process. The increased surface area in these fractured areas also allows for more chemical reactions to occur, breaking down the rock more rapidly.

How unloading acts as a weathering agent?
Unloading acts as a weathering agent by breaking bedrock into smaller pieces. This increases the surface area along which chemical reactions can occur, which eventually leads to weathering.

What is the Basal surface of weathering?
The basal surface of weathering refers to the base or bottom layer of material that is undergoing weathering processes such as physical or chemical breakdown. This layer is often in contact with the underlying bedrock or parent material, and serves as the point where weathering processes begin. The basal surface plays a crucial role in shaping landscapes and influencing the movement of weathered material.

Increased levels of carbon dioxide in the atmosphere can lead to more carbonic acid in rainwater, which accelerates chemical weathering of surface bedrock. Additionally, higher temperatures and increased precipitation can also enhance chemical weathering processes by speeding up chemical reactions and erosion rates.
Where is mechanical weathering occurred?
Mechanical weathering; as distinct from chemical weathering; occurs when the surface of a rock (say) is mechanically abraded. Such as the grits of a river wear away the bedrock. The aeolian sands in the desert will sculpt exposed rock ribs. A glacier will gouge the surface away by grinding the bedrock with boulders, stones, and grit entrained in the ice mass. This type of weathering produces vast quantities of rock flour. Much of the volume of a glacial valley has been turned into rock flour.
How do the temperature on earth vary?
The composition of soil mainly depends on the underlying bedrock, or weathering of surface rocks. Surface soil texture (on farmland, for instance) can be changed by using organic fertilisers.
How do soil horizon?
Soil forms as rock is broken down by weathering and mixes with other materials on the surface. Soil is constantly being formed wherever bedrock is exposed.Soil horizons form as a rock is broken down by weathering and then mixing with other materials on the surface.
Does Chemical weathering in bedrock below the land surface often begins along joints and sheeting fractures?
Yes, chemical weathering in bedrock often starts along joints and sheeting fractures because these areas provide pathways for water and other agents to penetrate the rock, accelerating the weathering process. The increased surface area in these fractured areas also allows for more chemical reactions to occur, breaking down the rock more rapidly.
What are the factors that influence the distribution of plants over earth's surface?
wind,water,erosion,weathering
How is the weathering of a bare mountain peak different from the weathering of bedrock under a forest soil?
A bare mountain peak may be exposed to freeze/ thaw cycles, harsh sunlight, surface erosion by wind blown and water carried particles, and chemical weathering from acid rain. Bedrock under soil is not exposed to most weathering forces.
