Age of Rocks
Determines the age of rock layers from youngest to oldest
What is relative dating?
The three types of rocks are
What are sedimentary, igneous, and metamorphic?
The Earth is composed of these main layers
What is crust, mantle, and core?
There are three main plate boundaries.....
What are convergent, divergent, and transform boundaries?
Give an example of metamorphic rock
What is marble, quartzite, or gneiss?
Uses radioactive material to determine the age of rocks
What is absolute dating?
What is sedimentary rock?
On this layer, you will find the thin surface of the Earth
What is the crust?
If two plate collide with each other, this type of boundary happens
What is convergent?
This period is part of the Mesozoic Era, and contained most of the dinosaurs that we know of
What is the Jurassic period?
The Law of Superposition states
What is "each rock layer is older than the one above it"
This type of rock is formed from extreme temperature and pressure
What is metamorphic rock?
This layer is made of iron and nickel, and is the hottest layer in the Earth
What is the core?
If two plates move away from each other, this type of plate happen
What is divergent?
Scientists use these to determine the age of the Earth
What are fossils?
Granite, a rock made from cooling magma, is an example of this type of rock
What is igneous rock?
You will find the lithosphere and asthenosphere, where convection currents occur, in this layer of the Earth
What is the mantle?
IF two plates move against or rub against each other, this type of boundary happens
What is transform?
The geologic time scale is
What is the “calendar” for events in Earth history?
The rock cycle is a ___________ cycle....
What is continuous?
We can compare the layers of the Earth to the layers of this object
What is an egg?
The theory of plate tectonics states that the movement of Earth causes___________
What is "slow and rapid changes in Earth's surface, including volcanic eruptions, earthquakes and mountain building"
