Science Module 6 Study

Front 1

Define Catastrophism

Back 1

The View that most of the earth's geological features are the result of larg-scale catastrophes such as floods, volcanic eruptions, etc.

Front 2

Define Uniformitarianism

Back 2

The View that most of the earth's geological features that are the result of slow, gradual, prosseses that have been at work for millions or even billions of years.

Front 3

Define Humus

Back 3

the Decayed Remains of once living creatures

Front 4

Define Minerals

Back 4

Inorganic crystalline substances found naturally in the earth

Front 5

Define Weathering

Back 5

The prosses by which rocks are broken down by the forces of nature

Front 6

Define Erosion

Back 6

The prosses by which sediments and rock fragments are carried away by wind or rain

Front 7

Define Unconformity

Back 7

A surface of erosion that separates one layer of rock from another

Front 8

What are the three basic types of rocks?

Back 8

igneous, metamorphic, and sedimentary

Front 9

What agent is responsible for laying down the most sedimentary rock we see today?

Back 9

Water

Front 10

Where do a large part of the sediments carried by a river end up?

Back 10

In The River's Delta

Front 11

What causes an underground cavern to form?

Back 11

Erosion caused by groundwater

Front 12

What is the difference between a stalacite and a stalagmite?

Back 12

Stalacites form on the ceiling of a cavern and stalagmites form on the ground

Front 13

What causes stalacites and stalagmites to form?

Back 13

Stalacites and Stalagmites are formed when groundwater seeps through the cavern's ceiling. As the drops form and fall to the floor of the cavern, it might deposit sediments on the ceiling or floor. As those sediments pile up Stalacites and Stalagmites are formed.
