8 Geo 103 Weathering & Erosion Padlet by Ridwan H

Erosion

rdwnhasibuan — 2024-05-05 18:52:21 UTC

Erosion is the removal of surface material from landforms, primarily soil and rock debris by wind and water. This material is then transported to a different location by the water or wind.

Weathering

rdwnhasibuan — 2024-05-05 18:52:34 UTC

Weathering is the breaking down or dissolving of rocks on the surface of the Earth. The process of weathering breaks down and removes material from the coastlines. Weathering wears away exposed surfaces over time.

Ice can erode the earth usually in the form of glaciers. Glaciers move slowly downhill and across the lands. As glaciers spread out over the surface they erode rock and sediment and carry it from one place to another. They change the shape of the land. As they move, they transport everything in their path, from tiny grains of sand to huge boulders. Rocks carried by glaciers scrape against the ground below, eroding both the ground and the rocks.

1) Wind erosion is when wind picks and moves the small particles of the rocks, soil and sand to different locations.

4) A way to reduce wind erosion is to planting windbreaks (rows of trees or shrubs) to reduce wind speed and protect soil. Another way is creating ridges or roughening the soil surface to trap moving soil particles.

Definition of biological weathering:

Biological Weathering occurs when plants and animals weaken and therefore break up rocks and other land forms. It is a slow process, but can have a drastic effect. Roots can burrow into rocks, or worms can dig into soil.

Water erosion is where the water carries weathered rocks and dust to other places

manmade weathering is a natural process that humans speed up. for example, certain types of air pollution releases chemicals into the atmosphere

An example of natural weathering is a rabbit which can burrow into the ground, which can cause weathering over time by breaking down the rocks and soil as the rabbit repeatedly hops on the ground

Gravity- Group 3, Lachy and Dylan

2024-05-05 23:42:52 UTC

Gravity is a common type of erosion that affects landforms all around the world. The way it works is that the gravitational pull of the sun which our planet orbits causes our planet to rotate. When this happens the strong gravitational pull of the sun can become greater than the friction of a area of terrain, causing it to errode. Some examples of gravity causing erosion include landslides, Cave-ins, avalanches and other highly destructive events. This type of erosion typically is either very slow, an area being eroded over a long period of time, or extremely fast and sudden like landslides or avalanches. Man made Gravity based Erosion includes events like landslides as a cause of deforestation or excessive mining causing the land to become loose and have much less friction, making gravity have a stronger force.

Manmade examples

chuhuang1 — 2024-05-05 23:44:46 UTC

Some Manmade examples of wind are windmills, wind farms, wind turbines and artificial wind generators.

Q2: Chemical Weathering is the process where chemicals in rocks react to other outside chemicals like rust which happens when the iron particles oxidise through the oxygen in the air.

Acid rain can be prevented by a drain system that slows the process of erosion.

water is a form of Erosion used to get rid of natural solids.

Q3 Pt 1: Some examples of man made chemical weathering is when acid rain falls after pollution has seeped into clouds making the rain turn acidic. This is an example of a forest after acid rain came down:

Natural example of wind erosion

2024-05-05 23:59:48 UTC

When the wind blows onto rocks it changes the way the rock looks and can change the location of the rock.

Natural Definition

Mechanical weathering is when rocks get broken down by water in solid or liquid form as well as temperature change.

Natural Example

One example of a ways rocks can crumble is when water runs through the cracks in a rock, and when it freezes, it causes the liquid to expand and it causes the rock to break into smaller pieces.

Man Made Definition

Mechanical Weathering can also mean breaking down rock by digging and blasting to crumble rocks another form of this is explosives'
