Q

What is comparative dating?

A

When geologists compare the properties of different fossils in the same layer to determine how old the organism has been deceased

17
Q

Who is the person who proposed “The Continental Drift” theory?

A

Alfred Wegener

18
Q

What is “The Continental Drift” theory?

A

“The Continental Drift” theory is the belief that the continents were once joined together as a super continent

19
Q

What was the supercontinent called?

A

Pangaea

20
Q

What is seafloor spreading?

A

When two tectonic plates split apart from each other

21
Q

What is the crust and the upper layer of the mantle called?

A

Lithosphere

22
Q

What are the 2 types of crust?

A

Oceanic crust and continental crust

23
Q

What is a convergent boundary?

A

Two tectonic plates moving towards each other and colliding

24
Q

What is a divergent boundary?

A

Two tectonic plates move apart

25
Q

What is a transform boundary?

A

2 tectonic plates sliding sideways past each other

26
Q

What natural disaster/s does a transform boundary cause?

A

Earthquakes

27
Q

What natural disaster/s does a convergent boundary cause? (memorize these, you will need them)

A

Earthquakes, volcanoes, and mountain ranges

28
Q

What natural disaster/s does a divergent boundary cause?

A

Earthquakes and volcanic eruptions

29
Q

Which type of rock do fossils form in?

A

Sedimentary

30
Q

How are large crystals formed?

A

When magma cools slowly

31
Q

How are small/no crystals formed?

A

When magma cools quickly

32
Q

Why do volcanoes and earthquakes appear on the outer lines of a tectonic plate?

A

Because the tectonic plates are unstable, making them create transform, convergent, and divergent

33
Q

What is the first step to fossil formation?

A

The organism dies

34
Q

What is the second step to fossil formation?

A

The organism is deposited to the bottom of a body of water with other sediments

35
Q

What is the third step to fossil formation?

A

The soft tissue of the organism decays

36
Q

What is the fourth step to fossil formation?

A

The sediment layers turn into sedimentary rock and fossilization occurs

37
Q

What are intrusive igneous rocks?

A

Rocks that are cooled slowly in the depths

38
Q

What are extrusive igneous rocks?

A

Rocks that are cooled quickly on the surface

39
Q

What natural disaster causes seafloor spreading?

A

Underwater volcanoes

40
Q

What do earthquakes do to the ground?

A

Uplift

41
Q

What rock has crystals?

A

Igneous

42
Q

What are fossils?

A

The imprint of an organism preserved in rock
