1.
The formation of igneous rock is related to magma. How is magma different from lava?
a)
Lava is magma that erupts onto Earth's surface.
b)
Lava is hot, liquid rock and magma is solidified lava.
c)
Lava forms intrusive rocks and magma forms extrusive rocks.
d)
Lava forms foliated rocks and magma forms nonfoliated rock.
2.
Clastic sedimentary rock and organic sedimentary rocks are both kinds of sedimentary rocks. What do they have in common?
a)
They are made up of the same kinds of minerals.
b)
They are formed when melted rock cools and hardens.
c)
They are made up of the remains of plants and animals.
d)
They are formed from layers of sediment.
3.
Which of the following best describes how sedimentary rock forms?
a)
molten rock beneath the surface of the Earth cools and becomes solid
b)
layers of material become compressed to form rock
c)
chemical processes or changes in pressure or temperature change the texture and composition of a rock
d)
molten rock reaches Earth's surface and cools to become solid rock
4.

sifting and floating
b)
heating and cooling
c)
uplift and subsidence
d)
erosion and deposition
