Rock Cycle Basics
The series of processes that continually change one rock type into another is called what?
Rock Cycle
Igneous rocks form when what cools?
Magma or lava
How many main types of sedimentary rocks are there?
Three
What is the original rock that changes into a metamorphic rock called?
Parent Rock
What process moves large amounts of rock toward Earth's surface and higher elevations?
Uplift
What are the three major types of rocks?
Igneous, sedimentary, and metamorphic rocks
Igneous rocks with small crystals are described as what?
Fine-grained
What process lays sediment down in a new location?
Deposition
Do metamorphic rocks melt when they form?
No. They remain solid.
What causes tectonic plates to move?
Earth's internal thermal energy and convection in the mantle
True or False: The rock cycle has a beginning and an end.
False — it is continuous.
Igneous rocks with large crystals are described as what?
Coarse-grained
What are the three main types of sedimentary rocks?
Clastic, chemical, and biochemical
Metamorphic rocks form when rocks are subjected to high temperature and what?
Pressure
What theory states that Earth's surface is broken into rigid plates?
Theory of plate tectonics
Name two processes that occur at Earth's surface as part of the rock cycle.
Weathering, erosion, deposition, compaction, or cementation
Igneous rocks that form when lava cools on Earth's surface are called what?
Extrusive rocks
What process pushes sediment grains closer together because of the weight of layers above them?
Compaction
What is nonfoliated rocks?
nonfoliated rocks have randomly arranged, interlocking grains.
What process moves large amounts of rock toward Earth's surface and higher elevations?
Uplift
What are two processes that can occur beneath Earth's surface and change rocks?
Extreme heat/temperature, pressure, or melting
Igneous rocks that form when magma cools inside Earth are called what?
Intrusive rocks
What is the process through which sediment turns into rock?
Lithification
What is Foliated rocks?
Foliated rocks have minerals lined up in layers
Earthquakes, volcanoes, and the formation of new crust commonly occur where?
Plate boundaries
