The geologic time scale is

What is a way scientist organize information about the history of the Earth

100

An index fossil has 4 main characteristics

1. Widely distributed

2. Easily recognizable

3. Short life span

4. Abundant

100

The person who discovered continental drift

Who is Alfred Wegener

100

Plates moving towards each other

What is a convergent boundary?

200

The current era is

What is the Cenozoic era

200

When a fossil is found in multiple layers of rock it is not

What is an index fossil

200
Pangea is

What is the supercontinent when all continents were connected

200

Plates moving away from each other

What is a divergent boundary

300

The current eon 

What is the Phanerozoic Eon

300

A fossil becomes more useful when

When it is widely distributed

300

No one believed Alfred Wegener because

What is he had no evidence

300

Plates that slide next to each other

What is a transform plate boundary

400

The oldest eons and eras a located on the

What is the bottom of the Geologic Time Scale

400

When a fossil lived for a long period of time we find it 

What is in multiple layers of rock

400

3 pieces of evidence for Continental Drift Theory are

What is continental fit evidence, fossil evidence, landform/rock evidence and glacial evidence

400

Convergent boundaries create

What is a mountain

500

There are 3 periods in the 

What is the Cenozoic era

500

When a fossil is not widely distributed it is less useful because

Scientist cannot correlate fossils as easily. Each continent would have to find their own index fossils.
500

Plates move this much during a year

What is about 3 cm

500

Transform boundaries cause

What are Earthquakes

600

There are 3 eras in the

What is the Phanerozoic Eon

600

A fossil is found in the layer above a trilobite. The trilobite lived 540-245 mya. The other fossil is approximently 

What is slightly younger than the Trilobite

600

The Mesosauraus is found in southern Africa and Eastern South America...How?

This is because those continents used to be connected

600

Divergent boundaries create

What are trenches, valleys, canyons, seafloor spreading

700

We live in this Epoch

What is the holocene epoch

700

Microscopic organisms do not make good index fossils

What is they are to small and not easily accessible to scientists.

700

Alfred Wegener died in the year of

What is 1930

700

The San Andreas fault is

What is a transform boundary
