Abrasion

Process where rocks are broken into pieces by CHEMICAL means.

a. Mechanical Weatheringb. Chemical Weathering

b. Chemical Weathering

Sudden, rapid movement of rock and soil down a slope.

a. Creep

b. 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.

True or False.

True

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

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?

1. Wind: wind blows the sand, abrasion, wearing down

rocks2. Water: waves create erosion

along the beaches.
