Rock Types
Name the three types of rocks.
Sedimentary, Metamorphic, and Igneous Rocks
Define weathering.
Breaking or dissolving of rock into pieces by wind, water, ice, or gravity.
The natural process of moving soil, rock, and sand from one place to another using wind, water, or ice.
When this is weathered and eroded, it turns into small pieces of pebble, silt, sand, etc.
What is sediments?
Magma is _____________ Earth's surface.
What is below?
This rock forms from melting magma or lava and then cools.
What is an igneous rock?
Define deposition.
Dropping or settling of sediment/rocks in a new location by wind, water, gravity, and ice.
Hard, solid materials made of naturally occurring minerals that form the Earth's crust.
What is a rock?
This type of rock is created within a volcano, melting and then cooling to solidify.
What is an igneous rock?
Lava is _____________ Earth's surface.
What is above?
This rock type needs heat and pressure from underneath Earth's surface.
What is a metamorphic rock?
Define erosion.
Movement of sediment/rock from one place to another.
The settling or dropping of sediments (sand, soil, rocks) by wind, water, or ice to create new landforms.
What is deposition?
This type of rock is weathered and eroded, and then is compacted and cemented together.
What is a sedimentary rock?
This rock type can contain many crystals or holes, depending on where it cools.
What is a igneous rock?
This rock type is compacted and cemented to make it.
What is a sedimentary rock?
Define compaction.
Layers of sediment are being pushed together from top to bottom.
The natural, slow process of breaking down rocks, minerals, and soil on Earth’s surface into smaller pieces using wind, water, ice, and plants.
What is weathering?
This rock type is pushed underneath the Earth's surface, where intense heat and pressure are applied to it.
What is a metamorphic rock?
List the layers of Earth in order from top to within Earth's surface. (Inner core, Crust, Upper mantle, Lower mantle, Outer core)
Crust, Upper mantle, lower mantle, outer core, and inner core
This rock is the only rock that contains fossils.
What is Sedimentary Rock?
Define cementation.
Sediments getting cemented or stuck together.
Natural, solid, inorganic materials found in Earth’s rocks, soil, and water.
What is a mineral?
What is true?
What rock type would take the most time to be formed?
What is a sedimentary rock?
Sedimentary rocks have to go through weathering and erosion to turn into sediments. After, sediments are compacted and cemented together to make a sedimentary rock.
