Answer 18

i mean a

Answer 19

D was right.

Answer 20

oh ok :3

Answer 21

Answer 22

i think b

Answer 23

Yes

Answer 24

Can any type of rock become igneous rock?

No, one type of rock cannot change into another type of rock
Yes, rocks at the surface can change from any type to igneous
Yes, if they are pressed down into the Earth's core and melt and cool to become igneous rocks
No, only volcanoes produce igneous rocks

Answer 25

i think d

Answer 26

Metamorphic rock can change into igneous or sedimentary rock. Igneous rock forms when magma cools and makes crystals. Magma is a hot liquid made of melted minerals. The minerals can form crystals when they cool.

Answer 27

so b

Answer 28

Igneous Rocks: form by crystallizing melted material (magma). They can form either on the surface (extrusive igneous rocks), or deep in the crust (intrusive or plutonic igneous rocks).

Answer 29

Answer 36

No and Yes

Answer 37

no its yes and yes bc on my lesson it said the weathering to break down a rock is wind and water so its wind and rain

Answer 38

Mechanical/physical weathering - physical disintegration of a rock into smaller fragments, each with the same properties as the original. Occurs mainly by temperature and pressure changes. Chemical weathering - process by which the internal structure of a mineral is altered by the addition or removal of elements.
