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
