metamorphic rocks are formed inside the Earth's.... | crust |
what two things turn rock into metamorphic rock? | Intense heat and pressure |
what are examples of metamorphic rocks (3) | 1. slate 2. marble 3. gneiss |
be able to draw what a metamorphic rock looks like | yes |
define rocks | a natural and non-living solid formation of one or more minerals |
define metamorphic rocks | rocks that are formed deep inside the Earth's crust from intense heat and pressure |
type of rock that is formed when magma or lava cools down | igneous rocks |
rocks that are formed after weathering and over time cement together to form into one rock | sedimentary rocks |
the continuous process in which rocks are changed from one type of rock to another type of rock | the rock cycle |
describe the rock cycle that changes metamorphic rock to sedimentary rock | weathering turns the metamorphic rock into sediments, then cementation turns the sediment into sedimentary rock |
describe how a metamorphic rock turns into an igneous rock | the metamorphic rock melts in the presence of lava/magma then cools to form igneous rock |
Igneous rocks are are formed when melted rocks do what? | cool and then harden into solid rock |
melted rocks below the Earth's surface are called | magma |
give 3 examples of igneous rock | 1) granite 2) diorite 3)magma |
why does magma cool slower than lava | because lava is not as hot as magma |
melted rocks that are under the earth's surface | magma |
type of rock that is formed when magma or lava cools down | igneous rocks |
the continuous process in which rocks are changed from one type of rock to another type of rock | the rock cycle |
3 examples of igneous rocks are | granite/ diorite/ magma |
why does magma cool slower than lava? | because it is hotter than lava to begin with. Its under the earth's surface. Once it reaches the surface, it's called lava- which cools more rapidly because it's exposed to the atmosphere |
igneous rocks are formed when melted rocks do what | cool and then harden |
melted rocks beneath the earth's surface are called | magma |
the moving of weathered rocks by wind or water | deposition |
the process of moving weathered rock | erosion |
small pieces of broken apart rocks | sediments |
when rocks break apart slowly due to the effects of the | weather |
rocks that are formed after weathering creates sediments and the sediments cement and form into one rock | sedimentary rock |
traces of dead plants or animals | fossils |
