Rocks

Explain the difference between extrusive and intrusive igneous rocks

An extrusive rock is found on the earths surface and is formed from lava. Intrusive igneous rocks are found on the interior of earths surface is and is formed from magma. Extrusive rocks form very quickly. Intrusive rocks cool

Rock

Any solid mass of material or mineral-like matter occurring naturally as part of our planet

What are the 2 types of sedimentary rock?

Clastic and Chemical

What factor most influences crystal size in igneous rock?

Cooling rate

What the 2 types of metamorphic rock?

Foliated and nonfoliated

How can an igneous rock become a sedimentary rock, then a metamorphic rock then igneous again?

For a igneous rock to become a sedimentary rock the rock is going to have to be weathered and eroded then deposited , which will then be compacted and cemented. For a sedimentary rock to become a metamorphic rock it can get stuck between tectonic plates or heat and pressure. Then for a metamorphic rock to become and igneous rock again it will to melt and then cool for the rock to form.

What are the energy sources for the rock cycle?

Heat from within the Earth forms igneous and metamorphic rock, the sun causes weathering and movement of weathered rock(sedimentary)

What are the three agents of metamorphism?

Heat, pressure, hydrothermal solutions

What type of rock does each energy source form?

Igneous and metamorphic rock come from the heat within the earth and sedimentary comes from the sun which causes weathering and movement.

What are the two types of igneous rocks?

Intrusive igneous rock and extrusive igneous rock

How and where do the two types form?

Intrusive rocks form from magma inside the earth, and extrusive forms from lava at the earth's surface.

What does the Law of Conservation of Matter tell us about the rock cycle?

The amount of rock within the rock cycle is constant

Texture

The shape, size, and pattern of the rock grains

How are the three types of rocks classified?

They are classified by how they form

What are the 4 major erosional agents?

Water, wind, ice, and gravity

List and explain the five steps in the formation of sedimentary rock.

Weathering, erosion, deposition, compaction, and cementation

Explain the rock cycle by describing how an igneous rock can become a sedimentary rock, then a metamorphic rock and then an igneous rock again (essay question).

When an igneous rock cools and melts, weathering and erosion will break off parts of the rock and then parts igneous rock will start to form layers to make sedimentary rocks. Heat and pressure will form from the sedimentary rock can turn that rock into a metamorphic rock, then when that rock melts into magma it cools and forms an igneous rock.

Metamorphic rock

formed by pressure and heat to rock deep within the Earth from sedimentary rock or igneous rock

Igneous rock

formed from cooling magma or lava

Sedimentary rock

formed when sediments are compacted and cemented

What are the three agents of metamorphism

heat, pressure, and hydro thermal solutions

What are the three agents of metamorphism

heat, pressure, hydro thermal solutions

What factor most affects crystal size in igneous rocks

how fast the igneous rock cools

What factor most effects crystal size in igneous rocks?

how fast the igneous rock cools

Lava

magma that reaches the earth's surface

Magma

molten rock deep in the earth

In which rock type would fossils most likely be found?

sedimentary

What are the three major types of rocks

sedimentary, metamorphic, and igneous

What are the three major types of rocks?

sedimentary, metamorphic, and igneous

What are four agents of erosion

water, wind, gravity, ice
