Which statement distinguishes between the two basic types of igneous rock?
Two igneous rocks are granite and basalt.
Different rocks have different size grains and different textures.
One type forms on Earth’s surface and the other forms below Earth’s surface.
The slower the rock cools and hardens, the larger its mineral grains will be.
What is the rock cycle?
the continuous process of volcanoes erupting
the continuous process of change in which rocks are created, destroyed, and recreated
the continuous process of sedimentary rock changing to become igneous rock
the continuous process of mineral grains making rocks smooth and shiny
metamorphic rock
the building blocks of rocks that consist of solid, nonliving substances
sedimentary rock
any process or force that moves sediments to new locations
minerals
a rock that forms when magma cools and solidifies; the most abundant class of rocks
erosion
a type of rock that forms when either igneous or sedimentary rock is changed due to extreme heat and pressure
igneous rock
a type of rock made of tiny bits of rock and sand mixed with small pieces of things that were once alive
sedimentary rock
a type of sedimentary rock that often has many fossils and shells of tiny ocean creatures
metamorphic rock
basalt, granite, and obsidian are examples of this class of rock
limestone
serpentine, marble, and gneiss are examples of this class of rock
igneous rock
sandstone, limestone, and mudstone are examples of this class of rock
