Igneous rocks are formed when this melted rock cools.
What is magma/lava?
100
These are little pieces of rocks that are smushed together.
What are sediments?
100
This is how igneous rocks are formed
What is magma/lava from volcanoes cooling?
100
In a rock layer, the oldest rocks are here.
What is the bottom?
100
This rock layer is the oldest (say the color of the layer)
What is the dark gray?
200
Rocks formed from sediments being smushed together
What is a sedimentary rock?
200
This is the process of wearing down rocks into sediments.
What is weathering?
200
These types of sedimentary rocks are formed when dissolved minerals come out of a solution.
What is a chemical sedimentary rock?
200
These types of fossils only lived on Earth for a really short amount of time.
What are index fossils?
200
This type of rock (be as specific as possible)
What is intrusive igneous rock?
300
These types of rocks are formed from extreme heat and pressure.
What is a metamorphic rock?
300
This is the process of carrying off sediments via wind or water.
What is erosion?
300
These types of sedimentary rocks are made from sediments being smushed together.
What is a detrital sedimentary rock?
300
The top layer of rocks are this.
What is the newest layer of rock?
300
These are two ways that geologists can figure out the age of rocks.
What are looking at rock layers and index fossils?
400
These types of igneous rocks are formed on the surface of the Earth from lava.
What is an extrusive igneous rock?
400
These two things are needed to change any type of rock into a metamorphic rock.
What are heat and pressure?
400
These types of sedimentary rocks are made up of things that were once living
What are organic sedimentary rocks?
400
The Earth is this many years old.
What is 4.6 billion years?
400
These are the three types of rock.
What are sedimentary, metamorphic and igneous?
500
These types of rocks are only found deep within the Earth's crust
What is a metamorphic rock?
500
These types of rocks can turn into one another.
What are ALL of them?!
500
These are the two differences between intrusive and extrusive igneous rock
What is the location they were made (intrusive beneath Earth, extrusive on Earth's surface) and their appearance (intrusive rocks are big and coarse, extrusive rocks are small and shiny)?
500
These three things must be true for fossils to be a good indication of the rock's age
What is abundance, spread over a wide geographical area, and lived for a short period of time?
500
This is how igneous rocks can become new igneous rocks.
What is melting, being forced under the earth, turning into magma and hardening again?
