Catastrophic Events
What are positives effects of a volcano?
Creates new land

What is a tsunami?
What is Erosion?
What is movie bits of rock or soil from one place to another by gravity, water, wind or ice (glaciers).
What is deposition?
What is the process in which sediments, soil, and rocks are added to landforms such as deltas, flood plains, sandbars, and dunes.
What is ecological succession?
Natural, gradual changes in the types of species that live in an area
What are positives effects of a flood?
Helps recharge the aquifer.
An overflowing of a large amount of water beyond its normal confines, especially over what is normally dry land
What is a flood?
What is an example of chemical weathering?
What is (answer will vary)
Oxidation - Iron combines with oxygen making rust

Carbonation - Carbon dioxide in rain water creates carbonic acid
What is an example of physical weathering?
What is (answers will vary)
Abrasion - by rapidly moving water, glaciers or wind
Ice Wedging - by freezing and thawing
Plant Roots
Burrowing
Temperature Change

What catastrophic could cause a tsunami?
What is a earthquake.

What is the difference between primary and secondary succession?
Primary succession starts with rock
Secondary succession starts with soil
