What are the examples of biotic weathering?

One type, biological weathering , is caused by animals and plants. For example, rabbits and other burrowing animals can burrow into a crack in a rock, making it bigger and splitting the rock. You may have seen weeds growing through cracks in the pavement.

How do animals break down rocks?

Plants and Animals in Mechanical Weathering Sometimes plants or animals cause mechanical weathering. Burrowing animals can also cause weathering. By digging for food or creating a hole to live, in the animal may break apart rock.

Which is an example of organic weathering of rocks?

Weathering is a process by which surface rock breaks down. Organic or biological weathering (for example, the roots of a tree grow into boulders in the soil and splitting the boulders apart over time)

What would be a simple way to prevent erosion?

You can reduce soil erosion by:

Maintaining a healthy, perennial plant cover.
Mulching.
Planting a cover crop – such as winter rye in vegetable gardens.
Placing crushed stone, wood chips, and other similar materials in heavily used areas where vegetation is hard to establish and maintain.

What landforms are created by glacial erosion?

As the glaciers expand, due to their accumulating weight of snow and ice they crush and abrade and scour surfaces such as rocks and bedrock. The resulting erosional landforms include striations, cirques, glacial horns, arêtes, trim lines, U-shaped valleys, roches moutonnées, overdeepenings and hanging valleys.

What are the two types of glacial erosion?

The two main types of erosion are:

Abrasion – as the glacier moves downhill, rocks that have been frozen into the base and sides of the glacier scrape the rock beneath.
Plucking – rocks become frozen into the bottom and sides of the glacier.

What are landforms shaped by erosion?

Some landforms created by erosion are platforms, arches, and sea stacks. Transported sand will eventually be deposited on beaches, spits, or barrier islands. People love the shore, so they develop these regions and then must build groins, breakwaters, and seawalls to protect them.

What landforms are erosional?

Erosional landforms include headlands, bays, caves, arches, stacks, stumps and wave-cut platforms. There are also depositional landforms such as beaches, spits and bars.

What are some examples of erosional and depositional landforms?

Erosional and depositional landforms

(
 Types of Erosional Landform: V-Shaped Valley Gorge and Canyon Waterfall  Pot hole  River Terraces  River Meanders.
 The valleys curved out by the rivers are significant erosional landforms.
 Gorges and canyons refer to the same basic landform.

What is created by deposition?

Landforms created by deposition include spits, salt marshes and beaches.
