What is the most abundant type of intrusive igneous rock found in the continental crust?
granite
100
What can heat and pressure beneath Earth's surface turn any rock into?
Metamorphic rock
100
What is the rock cycle?
A series of process that describes the continuous process of rock formation.
100
What is deposition?
The process by which sediment settles out of the water or wind carrying to the sea floor.
200
Which layer of Earth are the convection currents found?
Middle Mantle
200
How are extrusive igneous rocks formed?
Magma cools quickly on Earth's surface.
200
Where would you find rocks that have large crystalized grains?
Below the surface of Earth
200
Describe weathering and give me some examples of agents that causes weathering.
Weathering is the process of breaking down rocks caused by water, wind, ice, and gravity.
200
According to the rock cycle, metamorphic rocks can form from what type of rocks?
Igneous, Sedimentary, and Metamorphic
300
What can geologists use to map (study) the deep interior of the Earth?
a. seismic waves
b. sonar
c. ocean waves
d. information from drilling expeditions
Seismic waves
300
What characteristics do geologist use to describe a rock's texture?
The size, shape, and pattern of the rock's grains
300
Explain why metamorphic rocks are rarely formed at Earth's surface.
Metamorphic rocks are rarely formed at Earth's surface because most of them required the processes of intense heat and pressure that is found below or under the surface of Earth.
300
Explain the role of weathering in the formation of sedimentary rocks.
The weathered sediments are exposed to agents such as water or wind that can carry them and then deposit them in various places.
300
Explain the role of deposition in the rock cycle?
The sediments or pieces of rocks and soil are carried and dropped at the bottom of sea floor. Over a long period of time these sediments will be compacted and cemented and become sedimentary rocks.
400
In which layer would you expect pressure to be the greatest? Explain or support your answer.
The most amount of pressure would be found in the inner core. Pressure increases with depth towards the center.
400
What type of evidence can be found if holes are drilled into Earth's crust?
rock samples
400
What are two types of metamorphic rocks that are commonly used for building?
Marble and slate
400
What is the role of heat and pressure in the rock cycle?
It changes rocks into metamorphic rocks.
400
What are three processes that changed your rock during the journey activity last week?
Answers will vary: weathering, erosion, deposition, heat and pressure, melting etc....
500
Why do the plates of the lithosphere float on the asthenosphere?
The plates of the lithosphere are less dense than the asthenosphere.
500
In order list the processes of sedimentary rock formation.
Describe each process.
Weathering- breaking down of rocks
Erosion- the movement of weathered materials
Compaction - the sediments get flattened and pressed together
Cementation- the sediments and minerals are glued together
500
Why are chess pieces sometimes made of marble?
The even grain of marble allows it to be carved into many different shapes of the chess pieces.
500
What step in the rock cycle would be required to change granite (igneous rock) into a sandstone (sedimentary)?
Granite particles would have to be weathered (broken down), carried and deposited on the ocean floor.
500
In detail how can small pieces of the Himalayas mountains form new rocks?
What processes shape canyons?
small pieces are deposited on the sea floor, compacted, and cemented together
weathering and erosion
