Q

Origin of the Universe:
This theory proposes that the overall structure of the universe is always the same at any point in time and space. This structure is maintained even when certain events, such as birth of new stars, occur. It is balanced by the death of old stars.

52
Q

Part of the earth that life exist.

A

Biosphere

53
Q

It forms from the cooling of melted rock （either lava or magma into solid form.

A

Igneous rocks

54
Q

Form when existing rocks are subjective to intense heat and pressure, usually deep below the earth’s surface.

A

Metamorphic rocks

55
Q

These conditions change the original minerals of the rock into new minerals.

A

Metamorphic rocks

56
Q

Are either detrital or chemical.

Sedimentary rocks

57
Q

formed by the compaction of separate particles, or sediments, into a rock.

A

Detrital rocks

58
