Earth Science Rocks!Standard: Investigate the scientific view of how the Earth’s surface is formed.
Learning Target: Today I am learning about weathering because I don’t want my bike to become soil.

Weathering and Erosion
![Page 9: Earth Science Rocks! Warm up October 7](https://reader036.fdocuments.net/reader036/viewer/2022062521/5681665e550346895dd9e5d4/html5/thumbnails/9.jpg)
Weathering means the process of breaking down rocks and other substances at Earth’s surface.
![Page 10: Earth Science Rocks! Warm up October 7](https://reader036.fdocuments.net/reader036/viewer/2022062521/5681665e550346895dd9e5d4/html5/thumbnails/10.jpg)
Erosion means the movement of rock particles by wind, water, ice, or gravity.
![Page 11: Earth Science Rocks! Warm up October 7](https://reader036.fdocuments.net/reader036/viewer/2022062521/5681665e550346895dd9e5d4/html5/thumbnails/11.jpg)
Two Types OF Weathering:Mechanical (Physical) Weathering
is When rock is physically broken into
smaller pieces (but still have the same chemical composition).
Chemical weathering is Breaking down rocks through chemical changes.

There are 5 Types of Mechanical Weathering Freezing and Thawing Release of Pressure Growth of Plants Actions of Animals Abrasion
![Page 13: Earth Science Rocks! Warm up October 7](https://reader036.fdocuments.net/reader036/viewer/2022062521/5681665e550346895dd9e5d4/html5/thumbnails/13.jpg)
Freezing and thawing of water.
(Ice Wedging)- Water seeps into cracks in rocks and then freezes when the temperature drops. It expands when it freezes and acts like a wedge.
![Page 14: Earth Science Rocks! Warm up October 7](https://reader036.fdocuments.net/reader036/viewer/2022062521/5681665e550346895dd9e5d4/html5/thumbnails/14.jpg)
Release of pressure 1. Erosion carries away rocks from the top of a mountain. This reduces pressure on the rocks below and causes the outside rocks to crack and flake off like layers of an onion.
![Page 15: Earth Science Rocks! Warm up October 7](https://reader036.fdocuments.net/reader036/viewer/2022062521/5681665e550346895dd9e5d4/html5/thumbnails/15.jpg)
Plant action- 1. Plant roots grow in
cracks of rocks and pry rocks apart.
![Page 16: Earth Science Rocks! Warm up October 7](https://reader036.fdocuments.net/reader036/viewer/2022062521/5681665e550346895dd9e5d4/html5/thumbnails/16.jpg)
Actions of Animals Animals burrow in the ground and break apart
rocks.

Abrasion- rubbing by other rocks.
Sand and other rock particles carried by wind, water, ice, or gravity wear away rocks.

Water Oxygen (Rust) CO2 Living Organisms Acid Rain
Types of Chemical Weathering

Water Minerals are dissolved in water. ex.: Halite, calcite
![Page 21: Earth Science Rocks! Warm up October 7](https://reader036.fdocuments.net/reader036/viewer/2022062521/5681665e550346895dd9e5d4/html5/thumbnails/21.jpg)
Oxidation- Oxygen combines with water to make rust. (Oxidation)ex.: rusty bicycle
![Page 22: Earth Science Rocks! Warm up October 7](https://reader036.fdocuments.net/reader036/viewer/2022062521/5681665e550346895dd9e5d4/html5/thumbnails/22.jpg)
CO2 Carbon dioxide dissolves in rainwater to make
carbonic acid (weathers marble and limestone).
![Page 23: Earth Science Rocks! Warm up October 7](https://reader036.fdocuments.net/reader036/viewer/2022062521/5681665e550346895dd9e5d4/html5/thumbnails/23.jpg)
Living Organisms
Plant roots produce weak acids that dissolve rocks. Lichens grow on rocks and make weak acids.

Acid Rain:Burning fossil fuels causes sulfur, carbon, and nitrogen to mix with water vapor in clouds to make acid rain.
![Page 25: Earth Science Rocks! Warm up October 7](https://reader036.fdocuments.net/reader036/viewer/2022062521/5681665e550346895dd9e5d4/html5/thumbnails/25.jpg)
Rates of Weathering will depend on:
Surface area exposed - More surface exposed, the faster the weathering will occur.
![Page 26: Earth Science Rocks! Warm up October 7](https://reader036.fdocuments.net/reader036/viewer/2022062521/5681665e550346895dd9e5d4/html5/thumbnails/26.jpg)
A full, solid block has the least surface area.
The interior is safe from exposure.
A smashed piece has greatest surface area exposed. The interior can now be attacked.

Type of Rock - some rocks and minerals are more resistant than
others. – ex.:Quartz is resistant to chemical and
physical weathering. Slate tombstones weather slower than marble tombstones.
Rates of Weathering will depend on:

Climate:Cold and/or dry climates favor physical weathering. Warm and wet climates favor chemical weathering.
