What effect do small burrowing animals and earthworms have on the soil?

Small burrowing animals and earthworms have big effects on the soil and rocks in the ground. They take soil away from plants that need it and bury rocks underground.

How can earthworms cause weathering?

Did you know that earthworms cause a lot of weath- ering? They tunnel through the soil and move pieces of rock around. This motion breaks some of the rocks into smaller pieces. Any animal that burrows in the soil causes mechanical weathering.

What are four factors that affect how fast weathering happens?

Some features of climate that affect weathering are temperature, mois- ture, elevation, and slope. Temperature is a major factor in both chemical and mechanical weathering. Cycles of freezing and thawing increase the chance that ice wedging will take place.

Which one is not weathering agent?

Soil is the material which is formed as the result of wethering hence it is not the agent of wethering and this is the right answer.

How do plants break down rocks and turn into soil as years goes by?

Respiration of carbon dioxide by plant roots can lead to the formation of carbonic acid which can chemically attack rocks and sediments and help to turn them into soils. There are a whole range of weathering processes at work near the surface of the soil, acting together to break down rocks and minerals to form soil.

How do rocks turn into soil in water?

Under the action of heat, cold, rain, wind, and other atmospheric factors, the rock breaks down physically into small fragments that become the parent material of the soil. The rock also chemically changes as the compounds in the rock dissolve in rain or react with air.

Can soil be created?

Soils are limited natural resources. They are considered renewable because they are constantly forming. Though this is true, their formation occurs at extremely slow rates. In fact, one inch of topsoil can take several hundred years or more to develop.

How do rocks play an important role in the formation of soil?

They help in the formation of soil through a process called weathering. The type of soil under your feet is dependent on the bedrock deep below the surface. As the bedrock breaks down, smaller pieces move to the surface and mix with the existing soil.
