What causes burrowing in the ground breaks rock?
Burrowing animals can break rock through physical force, such as digging and tunneling, or through chemical processes like acid secretion. Over time, the repeated actions of burrowing can weaken and break apart rock formations.
Is frost heaving a type of mechanical weathering?
Yes, frost heaving is a type of mechanical weathering. It occurs when water freezes in the soil, expands, and lifts or heaves the ground surface. This process can lead to the breaking apart of rocks and soil particles due to the pressure exerted by the expanding ice.
What is animal weathering?
Animal weathering refers to the physical breakdown of rocks and other materials by animals through activities such as burrowing, digging, or grinding with teeth. This can contribute to soil formation and mineral breakdown in the environment.
What is an example of mechanical weathering by gravity?
An example of mechanical weathering by gravity is a rock falling down a steep cliff and breaking into smaller pieces as it hits the ground. This process is called rockfall and is a common way in which gravity causes mechanical weathering by physically breaking apart rocks.
How does a gopher cause weathering?
Gophers cause physical weathering. They dig burrows in the ground, allowing more rock to be exposed.
How can animals cause mechanical weathering?
roots and diggingPlant roots break up rocks as they grow in search of water and nutrients. Animals that burrow in the ground expose rocks to the air where they can be further weathered.When animals die they produce acids which reacts with rocks causing them to break down or decay.
A large rock falls from a cliff and break mechanical or chemical weathering?
When a large rock falls from a cliff, it primarily demonstrates mechanical weathering. This process occurs as the rock breaks apart due to physical forces, such as impact with the ground or other rocks, without altering its chemical composition. Over time, further exposure to elements like wind, water, and temperature changes may lead to additional mechanical weathering, while chemical weathering would involve changes in the rock's minerals due to chemical reactions.

What lives in a hole in the ground and is known for its burrowing abilities?
A mole lives in a hole in the ground and is known for its burrowing abilities.

How do mechanical weathering and chemical weathering help change earth's surface?
Mechanical weathering physically breaks down rocks into smaller pieces, while chemical weathering alters the chemical composition of rocks through processes like oxidation and hydrolysis. Together, these processes help to break down and wear away rocks, contributing to the shaping of Earth's surface over time.
Are weathering and erosion dependent on each other?
Weathering is the physical wearing down of rock or the earth, and erosion is the movement of the particles loosened by weathering. Weathering can be either mechanical or chemical. For chemical weathering to occur, a chemical reaction needs to occur in the ground, causing it to wear away. Mechanical weathering can include: freezing and thawing (water gets into ground and when it freezes it pushes the rock out), abrasion (force rubbing up against surface, such as water, which is why rocks in a river are so smooth), thermal weathering (rocks expand in very hot climates), salt wedges (rain with salt water in it falls into cracks between a rock and when the water dissolves, the salt is left behind pushing the rock outward), and animal activity (burrowing in the ground). Erosion would take place after one of these processes had, and it carries the weathered particles away by wind or water.

Gophers cause physical weathering. They dig burrows in the ground, allowing more rock to be exposed.
What are the causes of mechanical weatherig and chemical weathering?
Mechanical weathering can be caused by wind, precipitation (rain, hail, etc), animals walking over it, basically anything that is a physical abrasion of the rock, not a chemical reaction.
How did Burrowing Owls get their name?
they dig burrows in the ground
