Q

Are the App Mts. folded?

A

Yes

23
Q

Where does volcanic activity occur?

A

Zones of subduction, rifting, and sea floor spreading

24
Q

Why will a oceanic plate always sink under a continental plate?

A

The oceanic plate is more dense.

25
Q

What are P-Waves?

A

Primary waves travel the fastest & reach the seismic station first - they travel through solids, gases, and liquids, but they slow & bend as they move through the earth’s liquid outer core

26
Q

What are S-Waves?

A

Surfaces waves do not travel through liquids.

27
Q

What is weathering?

A

The process in which rocks are broken down by water, air, and organisms.

28
Q

When does chemical weathering occur?

A

It occurs fastest in warm, humid climates.

29
Q

When does mechanical weathering occur?

A

It occurs fastest in cold climates due to Ice Wedging.

30
Q

What is Erosion?

A

It is the process by which materials are transported by moving water, ice, or wind. Gravity is the force behind all of these agents of erosion.

31
Q

What are the major agents of erosion?

A

Streams and moving water.

32
Q

What is deposition

A

The dropping or settling out of sediments from water on the air.

33
Q

What does soil evolution start with?

A

The weathering of bedrock.

34
Q

Karst Topography -

A

An area that has limestone bedrock, dissolved by acidic groundwater to form caves and sinkholes.

35
Q

What is an aquifier?

A

A layer of highly permeable rock through which groundwater flows, sometimes over great distances.

36
Q

What is a spring?

A

An area where the water table reach’s the land’s surface

37
Q

What does the water cycle include the process of?

A

1) Evaporation
2) Condensation
3) Precipitaiton
4) Run-off

38
Q

What is a mineral?

A

A naturally occuring, inorganic solid, with a definite chemical composition and structure.

39
Q

What do VA’s natural resources include?

A

Limestone, Coal, & Gravel

40
Q

What is a fossil?

A

The remains (bone or tooth) impression (footprint) or other evidence of a dead life form preserved in rock.

41
Q

What does the Law of Superposition state?

A

That the obvious assumption that older rock layers are found underneath younger layers

42
Q

What does the Law of Cross-cutting relationships state?

A

That an igneous intrusion is younger that the layers it cuts across.

43
Q

What are ‘Superposition’ & ‘Cross-Cutting’ used for?

A

To find the relative ages of rocks & fossils.

44
Q

What are relative ages?

A

Rough estimates of how old a rock or fossil is, based on comparisons to the known ages of rocks and fossils located near to it.

45
Q

What is radioactive decay rates and half-life used to determine?

A

The absolute age of rocks

46
Q

What does Uranium dating do?

A

Used to find the ages of the oldest rocks

47
Q

What is Carbon-14 dating used for?

A

To find the ages of human artifacts and fossils of living things that have died in the last 50,000 years..

48
Q

How old is the earth?

A

About 4.6 billion years old

49
Q

What are unconformities?

A

Missing rock layers, usually a result of erosion.

50
Q

What are tides caused by?

A

The gravitational pull of the Earth and Moon on the oceans.

51
Q

What are currents resulted in?

A

The cold movement of the ocean water in warm areas.

52
Q

What does upwelling bring?

A

Cold, nutrient-rich water from the bottom of the ocean to the surface.

53
Q

What are estruaries? List at least one.

A

Where salt water mixes with fresh water. The Chesapeke Bay is an example.

54
Q

When does the sea level rise?

A

When ice caps and glaciers melt from land areas.
