Rock

Question 1

How far have geologist drill holes in the Earth?

Answer 1

12.3 km

Question 2

What do these drills do?

Answer 2

they bring back rock samples to help geologist learn about the earths interior

Question 3

What other things do geologist use to help them?

Answer 3

Seismic waves created by things like earthquakes

Question 4

What do the path of these waves show?

Answer 4

They show how they travel through the Earth as well as the make up how rocks change over time

Question 5

What are the three layers of the Earth?

Answer 5

Crust mantle, and core

Question 6

What do these layers vary in?

Answer 6

Thickness, composition, temperature, and pressure

Question 7

What is pressure created by?

Answer 7

Force being pressed on something and rocks pressing down from above causes more and more pressure the deeper you travel in the core

Question 8

True or false is temperature increase the farther you go into the earth core

Answer 8

True

Question 9

How does temperature rise inside the Earth?

Answer 9

Fairly rapidly a deeper you go, but it does start to slow its rate of change as the core gets closer

Question 10

What does this high temperature release in the core?

Answer 10

Most likely the release of energy from radioactive substances near the core

Question 11

What is the outer layer of the Earth surface?

Answer 11

The crust and its main elements in the layer are oxygen and silicon this layer Is also much thinner

Question 12

True or false is the crust thick

Answer 12

No, the crust is thinner than the other layers of the Earth. Between five and 40 km in the Earth.

Question 13

What are the two types of crust

Answer 13

Oceanic and continental

Question 14

What is Oceana crust made of?

Answer 14

A fine-grained rock called basalt

Question 15

What does continental crust contain?

Answer 15

Granite

Question 16

What is the mantle made of?

Answer 16

Magnesium and iron and is a layer of hot rock that’s 3000 km thick

Question 17

What is the upper mantle?

Answer 17

The upper mantle is a firm and rigid like the crust scientist combine the crust and upper mantle in a layer called the lithosphere

Question 18

What is the layer below the lithosphere?

Answer 18

The layer below the lithosphere is increasingly hotter. It’s less rigid. It’s in the part of the mantle. It’s able to be bent like a metal spoon even though it may be a solid. This layer is called asthenosphere

Question 19

What is beneath the asthenosphere?

Answer 19

A hot rigid layer that is under a great amount of pressure this layer the lower crust and reaches the core

Question 20

where is the the core?

Answer 20

Below the mantle, our stance core at the center of the planet

Question 21

What is the outer core?

Answer 21

The outer core is liquid molten metal surrounding the solid inner core even though there is enormous pressure. The temperature allows this layer to be liquid.

Question 22

What is the inner core?

Answer 22

The inner core is a dense ball of solid metal. The pressure here is so high at the atoms of iron and nickel cannot expand due to the high temperatures.

Question 23

What does the outer core cause the Earth?

Answer 23

The outer core causes the magnetic field of earth to develop, and the magnetic field of earth allows us to orbit the sun

Question 24

What do convection currents do to the mantle

Answer 24

Since heat moves hot to cold, the heat moves outward toward the surface because of its liquid like steak of these layers and the cycle back again when it cools down and hot springs are a good example of this at the surface

Question 25

What are minerals?

Answer 25

Minerals are naturally occurring solids that can form by inorganic processes and have a crystal structure and a definite chemical composition

Question 26

What are the properties of minerals?

Answer 26

hardness color density and crystal structure

Question 27

True or false can minerals form from living things

Answer 27

True, your bones are made out of minerals

Question 28

How does water help make crystals?

Answer 28

Some minerals are left behind after water, absorbs different elements and leave behind minerals when the water evaporates because of the pressure crystallization can occur

Question 29

How do minerals form from magma and lava?

Answer 29

Minerals can form when hot, magma cools higher up in the crusts or on the surface. This liquid turned into a solid state and then forms crystals, slow, cool cooling magma results in large crystals and fast cooling magma results in small crystals.

Question 30

What are altered minerals?

Answer 30

Changes in temperature and pressure can alter one mineral into another graphite is a good example cause it’s made of pure carbon when he impress rise. This carbon can turn into diamonds.

Question 31

What happens when rocks change their appearance

Answer 31

Weathering, erosion, transportation and deposition are ways. Rocks can change their appearance, geologist, describe rocks and three main ways and they are mineral compositions texture, and the origin of the rocks.

Question 32

What is mineral composition in rocks

Answer 32

Some rocks are made of a single mineral others are made of a combination of minerals 20 minerals make up the majority of our crust. These minerals are known as rock forming minerals.

Question 33

What is the texture of rock

Answer 33

Most rocks are made of particles that geologist called grains when describing texture geologist use terms based on a size shaping pattern of the grains

Question 34

What is the origin of rocks?

Answer 34

When geologist use composition, color and texture, they can find the origin of the rock. There are three main groups of which rocks originate. They are igneous rock, sedimentary rock, and metamorphic rock.

Question 35

How does igneous rock form?

Answer 35

Igneous rock forms from cool, magma or lava igneous rock looks different from each other based on the temperature. It was formed at and the composition of the rock igneous rock has two main forms extrusive, which is the type of igneous rock or lava erupted, and then cooled and intrusive the igneous rock that hardens below the surface of the Earth

Question 36

How to sedimentary rock form

Answer 36

Sedimentary rock is formed in small particles of rock or the remains of plants and animals are pressed together by themselves. They are raw material called sediment and they are pressed together. They become sedimentary rock sedimentary rock moves through a sequence of processes like weathering and erosion transportation, deposition, compaction, and cementation create the sedimentary rock.

Question 37

How does metamorphic rock form

Answer 37

Metamorphic rock forms when rocket has changed by heat pressure or chemical reactions when heat or pressure. I replied to rock the shape, texture, composition and change most metamorphic rock is formed deep inside the Earth for heat and pressure is much greater than at the Earth surface

Question 38

True or false energy drives rocks

Answer 38

True, no matter what kind of rocks forms is all result of the energy that flows through earth systems

Question 39

What is sedimentary rock in the rock cycle?

Answer 39

Weathering, erosion, transportation, deposition, compaction, and cementation are all part of the rock cycle when creating the sedimentary rock

Question 40

What is the rock cycle?

Answer 40

The rock cycle has no particular order and is constantly building, destroying and changing rocks and sediment this cycle mainly takes place on the Earth surface and inside of the crusted energy also plays a big factor in the rock cycle. That’s why there are many pathways to this cycle

Question 41

How is the rock cycle driven?

Answer 41

The rock cycle is driven and part By plate, tectonics huge plates are formed in the lithosphere because of the mantle convection currents the solid plates move around with when they move. They carry sediment with them. These movements help drive the rock cycle while helping for magma, especially on the surface.

Question 42

True or false our materials in the rock cycle lost or gained

Answer 42

False just like the water cycle materials in the rock cycle are not lost or gained. They are recycled it away and use for different purposes.

Question 43

When rocks recycle do they can they form new and different types of rocks?

Answer 43

Yes,new and different types of rock happens frequently throughout the rock cycle
