32
New cards

What is the difference between weathering and erosion?

Weathering chemically breaks things down and erosion carries perticles away

33
New cards

What is the biosphere?

The parts of earth where life exists from the roots of trees to the depths of the oceans and the high mountaintops. The biosphere overlaps all other spheres since life exists on the ground, in the air, and in the water.

34
New cards

What is the hydrosphere

The Earth’s water including on the surface, in the ground, and in the air

35
New cards

What is the geosphere?

All solid portions of the earth including the oceanic crust and all other layers of the Earth’s interior

36
New cards

What is the atmosphere?

The layer of gas and suspended solids extending from the Earth’s surface

37
New cards

What are the four layers of the atmosphere from closest to furthest from Earth?

Troposphere

Stratosphere

Mesosphere

38
New cards

Which part of the atmosphere do we live in?

39
New cards

Which layer of the atmosphere contains most of our weather

Troposphere

40
New cards

Which part of the atmosphere contains most of our weather

Troposphere

41
New cards

What is the temperature like in the troposphere?

The temperature gets colder as the distance above Earth increases

42
New cards

What is the boundary layer?

The lowest part of the troposphere where air motion is determined by properties of the Earth’s surface. Turbulence redistributes heat, moisture, pollutants, and other constituants of the atmosphere within the boundary layer

43
New cards

What is the tropopause?

The top of the troposphere

44
New cards

Which layer of the atmosphere contains much of the ozone in the atmosphere

Stratosphere

45
New cards

What is temperature like in the stratosphere?

46
New cards

Stratosphere

47
New cards

What is the rock cycle?

The processes through which igneous, metamorphic, and sedimentary rock transform from one type to another

48
New cards

How are sedimentary rocks formed?

From pieces of other existing rock or organic material.

49
New cards

What are clastic sedimentary rocks?

Form from pieces of other rock (clasts)

50
New cards

What are organic sedimentary rocks?

Form from hard, biological materials like plants, shells, and bones that are compressed into rock

51
New cards

How are clastic and organic rocks formed?

Exposed rock is broken down into small fragments through weathering. Erosion moves these fragments and settles the sediment somewhere where it builds up and the lowest layers become compacted so tightly that they form solid rock. `

52
New cards

How are chemical sedimentary rocks formed?

Through chemical precipitation where a chemical compound forms when the solution it is dissolved in evaporates and leaves the compound behind.

53
New cards

What are some types of sedimentary rocks?

coal, limestone, sandstone, flint

54
New cards

What are metamorphic rocks?

Rocks that have been changed from their original form by immense heat or pressure. There are two classes: foliated and nonfoliated

55
New cards

What is a foliation?

Aligning of elongated minerals perpendicular to the direction of the pressure that is applied

56
New cards

What are igneous rocks?

Rocks formed when molten hot material cools and solidifies

57
New cards

What are intrusive (plutonic) igneous rocks

Rocks formed inside the Earth

58
New cards

What are extrusive (volcanic) igneous rocks?

Rocks formed outside of or on top of the Earth’s crust.

59
New cards

How are mountains formed?

  1. The collision or overlapping of plates

  2. The raising or tilting of a fault-block

  3. Volcanos

60
New cards

How are canyons formed?

The movement of rivers and a combination of weathering and erosion

61
New cards

How are ocean trenches formed?

Subduction: Two or more tectonic plates collide and the older and denser plate is pushed beneath the liter plate deep into the mantle which causes the seafloor and outermost crust to bend and forma steep V-shaped depression.
