The breakdown of rocks into smaller particles.Weathering The breakdown of rocks into smaller particles. 2 Types Physical: Only size and shape changes. Chemical: composition changes
What causes physical weathering?Ice = freezing and thawing (frost cycle).
Physical Weathering Wind = rocks get pitted from blown particles.Ventifact = angular, pitted rock with 1 or more flat sides.
Physical Weathering Water = rocks become round, smooth and smaller.Abrasion = rocks break down from rubbing against each other.
4. Plants = roots grow and expand, breaking rock apart.Physical Weathering 4. Plants = roots grow and expand, breaking rock apart.
Physical Weathering Animals = Ants / Worms Humans
Chemical Weathering 3 Types Oxidation = reaction with O2Hydrolysis = reaction with H2O Carbonation = reaction with CO2 ** Occurs faster in hot and wet weather.
Weathering Earth Science – Ms. Bray.
Mechanical Weathering Directions: Read the passage. Mechanical weathering is a type of weathering where rock is physically broken down into smaller pieces.
Mechanical Weathering. What is Mechanical Weathering? Weathering where the chemical make up of the rock is not changed, but the rock is broken into smaller.

Topic 4: Weathering, Erosion and Deposition
The Process of Weathering Rocks. Weathering The breaking down of rock into smaller pieces that remain next to each other. Weathering forms sediments.
Weathering: The natural process by which atmosphere and environmental forces, such as wind, rain, and temperature changes, disintegrate and decompose.
Rocks and Weathering Chapter 6 Section 1. Weathering and Erosion Weathering is the process that breaks down rock and other substances at Earth’s surface.
Weathering and Erosion
Mechanical and chemical forces break down rock When you are walking in your neighborhood how do you think the small rocks are formed?
Weathering The breakdown of the materials of Earth’s crust into smaller pieces. It can happen through physical or chemical means and through natural and.
Weathering and Erosion Weathering means the process of breaking down rocks and other substances at Earth’s surface.
Types of Weathering ____________ Weathering only changes the shape. __________ Weathering changes the composition.
Science Starter Pick up a post-it note at the front desk and answer the following questions… What is weathering? What is erosion? Place your post-it note.
