Weathering The breakdown of rocks into smaller particles. 2 Types 1.Physical: Only size and shape changes. 2.Chemical: composition changes
Physical Weathering What causes physical weathering? 1. Ice = freezing and thawing (frost cycle).
Physical Weathering 2. Wind = rocks get pitted from blown particles. Ventifact = angular, pitted rock with 1 or more flat sides.
Physical Weathering 3. Water = rocks become round, smooth and smaller. Abrasion = rocks break down from rubbing against each other.
Physical Weathering 4. Plants = roots grow and expand, breaking rock apart.
Physical Weathering 5. Animals = Ants / Worms Humans
Chemical Weathering 3 Types 1. Oxidation = reaction with O 2 2. Hydrolysis = reaction with H 2 O 3. Carbonation = reaction with CO 2 ** Occurs faster in hot and wet weather.
Weathering Chapter 6, Section 1. Weathering and Its Effects Weathering Surface processes that break down rock. Rock breaks down into sediment. Sediment.
Rocks and Weathering EQ: What is chemical and mechanical weathering?

Weathering and Erosion. Weathering The breakdown do the materials of Earths crust into smaller pieces.
6. Minerals and Rocks 6.1 Minerals are all around us 6.2 Rocks form in different ways 6.3 Natural processes break down rocks 6.4 Geologic maps show Earths.
Weathering. Definition Weathering is the breakdown of materials of the Earths crust into smaller pieces. (sediment) No movement is involved. Surface or.

The Water Cycle. Processes in the Water Cycle The water cycle is made up of 5 processes The water cycle is made up of 5 processes –Evaporation/transpiration-
Weathering and Soil Test Review. Question 1 True or False: After chemical weathering, the chemical make up of the rock is the same. False.
WEATHERING AND EROSION Rock Cycle WEATHERING I. Weathering - The breakdown of rock due to exposure to the atmosphere, weather, plants, and animals.
What is a rock?. A rock is a naturally occurring solid mixture of one or more minerals or organic matter.
Rates of Weathering What is differential weathering? How does surface area affect the rate of weathering? How does climate affect the rate of weathering?
Weathering is the break- up of rock due to exposure to the atmosphere.
