Rock Cycle (level 3)

How is the rock cycle related to plate tectonics?

• the two are not related

• convection in the mantle

• the plates move causing rocks to rise to earth's surface where they erode or bring rocks down where they are metamorphosed. The motion causes the rocks to melt then turn them solid

• weathering and erosion

Intrusive and extrusive only happen for _________ rocks?

What has to happen to a sedimentary rock in order for it to form into an igneous rock?

• it must be weathered and eroded

• it must become cemented to other rocks

• it must be put under pressure

• it must melt, then cool, then harden

• it must allow new minerals to form in it

Why does the rock cycle have no order?

What is present in sedimentary rocks?

• fossils

• holes/air bubbles

• different rocks and minerals

• crystals

• colorful layers

what are some ways rocks change over time?

• weathering, deposition, and erosion

• burial, heating, pressure

• all of the above

• melting and cooling

Could this statement be true? Igneous rock is eroded to form metamorphic rock.

What type of rock is formed when broken pieces of any kind of rock are deposited into layers and cemented together?

• sedimentary rock

• metamorphic rock

• igneous rock

• delta

The uppermost part of the mantle is part of Earth's ______________.

"metamorphic" means

• a melting process

• transformation of existing rock types

• a change in form

• to be broken down
