Types of Rocks
What are the three types of rocks?
Metamorphic, Igneous, Sedimentary
What is natural, non-living and makes up rocks?
Minerals
What makes rocks change?
heat, weathering/erosion and cooling and pressure
What is the process where the rock is dissolved, worn away, or broken down into smaller pieces?
weathering
If igneous rocks have small grains, small crystals, and a smooth texture, did it cool quickly or slowly?
What type of rocks form from magma that has cooled and hardened?
Igneous Rocks
Minerals have different __________, or ways to describe something.
properties
How long does it take for a rock to go through a rock cycle?
millions of years
What happens when rocks and sediments are picked up and moved to another place by ice, water, wind or gravity?
If an igneous rock has large grains, large crystals, and rough texture, then it cooled quickly or slowly?
slowly
These rocks form from layers of sediment that are pressed together.
Sedimentary Rocks
How many properties are there for minerals?
5
When igneous rocks go through weathering and compaction, what type of rock does it become?
sedimentary
mechanical, chemical, and organic
The rock cycle is _____________.
continuous
What type of rock start as another type of rock, and change because of extreme heat and pressure?
Metamorphic rocks
What are the 5 types of properties of minerals?
color, hardness, luster, streak, cleavage.
When sedimentary rocks get heat and pressure added to them, they become what type of rock?
This happens when plants break up rocks with their growing roots or plant acids help dissolved the rock.
Which of those examples are NOT an example of sediment?
Sleet
