Biological Weathering by Algae, Lichens, and Mosses

The organisms carry small amounts of acid that can weather the thins it grows on

After building roads construction workers will saw a line in the middle and fill it with tar. This helps so that if the water freezes and the road expands the tar can stretch.

This happens when iron-barring materials get exposed to oxygen and react. The atoms lose electrons and weather down an example of weathering from oxidation is rust.

Mud slides occur when dirt gets wet and begins to flow like a river. The mud that flows can take out houses and destroy animal habitats. It can also take down rows of trees and bushes.

Over time glaciers move and the compacted snow slides across the rock underneath which breaks the rocks into small particles. Those particles keep getting weathered down by the compacted snow.

In space the temperatures of rocks can change by how close or how far it is away from a star. Also rocks and planets can be weathered by asteroids and comets colliding with them in space.

As the water carries the rocks the particles become smaller and more rounded.

# data[].attributes.body
The wind carries rocks and the rocks become smaller and more rounded.

# data[].attributes.body
Animals walk on top of rocks and the ground and weather it over time.

# data[].attributes.body
Plant roots grow in cracks of the rocks and as they grow they start to crack the rocks into smaller pieces for it to grow.

The movement of weathered rocks.

When animals and plants weather rocks.

Fossil fuels get released into the air and when they do clouds absorb them. This makes the rain more acidic than normal and when it rains rocks such as limestone can react to them and weather down.

A way rocks can weather due to chemicals.

# data[].attributes.body
When rocks heat up they expand and when they cool down they contract. This constant heat up cool down cracks the surface of the rocks and it weathers it down.

The river and ocean current already can weather rocks by itself but when those tiny rocks crash into each other which causes the rocks to weather even more. It also makes the rocks have a more rounded and smooth surface.

The process starts when water gets into a crack of a rock. Once it is in the crack it freezes and expands which makes the crack even bigger. It then repeats the process and eventually it can split the rock.

Rust can be prevented by frequent washing and waxing of your car, boat, bike, etc. Once the item is washed, it is best to let it sit in the sun for a few hours to let it dry.

Wind can take small pieces of rocks and throw them into other things such as larger rocks, houses, the ground which makes them smaller. An example of wind weathering is sandstorms which can create amazing rock formations.

Physical weathering is caused by nature such as wind, temperature change, waves, and rain. As they move the rocks they smash into other stuff which makes them even smaller.

Its the process when rocks gradually wear away.
