Presentation transcript:

Type of mechanical weathering where rocks are worn away by contact with OTHER rocks. Plants Abrasion Ice wedging Animals

Process where rocks are broken into pieces by CHEMICAL means. Mechanical Weathering Chemical Weathering b. Chemical Weathering

Sudden, rapid movement of rock and soil down a slope. Creep Mass Movement b. Mass Movement

Process were rocks are broken into pieces by PHYSICAL means. Mechanical Weathering

Process where oxygen reacts with metal causing rust. Oxidation

Slow movement of material down a slope. Creep

Process by which streams dump (deposit) sediment. Deposition

Cycles of freezing and thawing of water which causes rocks to break. Ice Wedging

Large masses of snow and ice that cover about 1/10 of the Earth’s surface. Glaciers

Glaciers push these rocks and materials in front of them called. Deposit Sediment b. Sediment

Weathering is the process where rocks are broken down. True or False. True

The process of rock and sand being moved from one place to another. Weathering Erosion b. Erosion

Identify the chemical weathering cause of this cave. Acids

This type of mechanical weathering can cause erosion. Plant Growth

This type of mechanical weathering can cause erosion. Animals

List the 4 types of Erosion Wind Water Gravity Glaciers

What agent of erosion caused this? Gravity

What agent erosion caused this? Glaciers

What agent erosion caused this? Running Water What type erosion caused this? Running Water

What agent erosion caused this? Wind

2 Ways Plants can PREVENT Erosion! 1. Roots: hold soil together. 2. Body of the plant: prevent soil to be eroded by wind and water.

What agents of erosion continue to change Long Island Sound? Wind: wind blows the sand, abrasion, wearing down rocks Water: waves create erosion along the beaches.
