17
Q

What clues would help you determine the type of igneous rock is where it was formed?

A

Weather is coarse or fine-grained as well as the type of rock.

18
Q

How is sand formed?

A

Formed by the result of weathering of all three rock types.

19
Q

What is weathering?

A

It is wind, water, ice, sunlight, and gravity.

20
Q

What does weathering do to rocks?

A

It causes sediment.

21
Q

What does erosion do?

A

It causes sediments.

22
Q

What is deposition do?

A

It is where sediments finally land.

23
Q

What turns sediments into sedimentary rock?

A

It compaction and cementation.

24
Q

What is found in sedimentary rocks?

A

fossils.

25
Q

What is an example of sedimentary rocks?

A

Limestone.

26
Q

What is always happening to rocks?

A

rocks are always being recycled.

27
Q

What is mechanical weathering?

A

It is the process that breaks rocks apart without changing their chemical composition.

28
Q

What are examples of mechanical weathering?

A

It is freezing water, deep rocks in the earth under pressure, plants making cracks in cement, water wearing down rocks.

29
Q

What are chemical waves?

A

It is water causes chemical weathering water/oxygen combines with iron to cause rust.

30
Q

What are the sand colors?

A

orange, grey, violet, red. black, green, dark brown, pink, white, and tan.

31
Q

What are some of the beach materials?

A

glass, shale, shells, volcanic minerals, and sand.

32
Q

where are igneous rocks formed?

A

They are formed on volcanic surfaces or inside the crust.

33
Q

What prosses create igneous rocks?

A

cooling of magma.

34
Q

Where are sedimentary rocks formed?

A

They are formed near water.

35
Q

What prosses create sedimentary rocks?

A

It is formed by compaction.

36
Q

Where are metamorphic rocks formed?

A

It is formed on mountain ranges and deep in the earth.

37
Q

What prosses create metamorphic rocks?

A

Heat and pressure from sedimentary rocks create metamorphic rocks.

38
Q

What was the first part of the starburst lab?

A

Pulling it apart and making it sediments.

39
Q

What was the second part of the starburst lab?

A

Applying heat and pressure makes it metamorphic rocks.

40
Q

What was the third step in the starburst lab?

A

The third step was to heat for thirty seconds, making it into an igneous rock.

41
Q

What is magma?

A

Magma is found beneath the surface of the Earth.
