Layers of the Earth
What is the thickest layer of the earth?
Mantle
Which plate boundary is it that the plates are pushed together?
Convergent
How many rock types are there? and what are their names?
3 types: Igneous, Sedimentary, and Metamorphic
What is the breaking down or dissolving of rocks and minerals on Earths surface due to wind, water, and ice?
Weathering
What is something paleontologist collect from sedimentary rock to tell them about the animals or plants from past?
fossils
What is the thinnest layer of the earth?
Crust
What plate boundary has plates that slide past one another creating friction that eventually causes earthquakes?
Transform
What is it called when rocks are continually changing into other types of rock?
Rock Cycle
Igneous rocks can change into what kind of rock if they are broken down into sediments and then those sediments compact and cement together?
Sedimentary rocks
True or False: Fossils found in deeper rock layers are younger than fossils found in rock layers above them.
False
The layer of the earth that is hot, semi solid like honey.
Mantle
True or False: The effects of all the different plate boundaries (ex. mountains, volcanoes, earthquakes) are caused by underground thermal energy.
True
Which rock type is made up of layers of sand, mud and pebbles?
Sedimentary
Sedimentary rocks can change into what kind of rock if pressure and heat is applied?
Metamorphic rock
What is one way that fossils are useful?
1. Fossils help scientists understand how and where extinct plants and animals once lived
2. Fossils provide information about life and conditions of Earth’s past.
A layer of earth made of solid iron and nickel?
Inner core
Which two plate boundaries cause mountains and volcanoes?
Divergent and Convergent
Which type of rock is made from cooled magma or lava?
Igneous
What is it called when sediments are carried to another place and then accumulate or pile up?
Deposition
What are natural resources that cannot be replaced after they are used? (Nonrenewable or Renewable)
Nonrenewable
A layer of earth made of liquid iron and nickel?
Outer core
What plate boundary type formed the Mid-Atlantic Ridge?
Divergent
Metamorphic rocks are other rocks that have changed over time due to?
heat and pressure
What is the geological process in which earth materials are worn away and transported by natural forces such as wind or water.
Erosion
Wind, Solar, Wood, Water are renewable or nonrenewable materials?
Renewable
