These are the 2 characteristics we use to classify igneous rocks.
What is color and texture?
100
This layer of earth is the youngest if there are no cross cuts.
What is the top layer?
100
This causes a rift valley.
What is diverging plates?
100
This is all of the ash and lava ejected from a volanco.
What is a tephra plume?
100
Plate tectonics are located in this layer of the Earth.
What is the lithosphere?
200
This is how metamorphic rocks are formed.
What is through heat and pressure?
200
This is the name for a fracture in the earth.
What is a fault?
200
This is where most volcanoes are found.
What is at a plate boundary?
200
This is the volcanic hazard that travels the farthest.
What is ash?
200
This is thought to provide the energy that moves tectonic plates.
What is convection currents within the mantle?
300
This type of sedimentary rock forms from broken pieces of rocks compacted or cemented together.
What is clastic sedimentary?
300
This is the type of fault that occurs when the top layer of earth slide down relative to the bottom layer.
What is a normal fault?
300
This type of magma has a high viscosity and does not flow well.
What is high silica magma?
300
A tiltmeter is used to predict volcanic eruptions. This is also used to predict eruptions.
What is an increase in earthquake activity?
300
This is why most of the mountain ranges form on the planet.
What is because of colliding plates?
400
This type of sedimentary rock forms from dead plants and animals.
What is organic sedimentary?
400
This is the direction North America is moving.
What is west?
400
This type of magma produces shield volcanoes.
What is low silica magma?
400
This is why we monitor volcanoes.
What is to save lives?
400
This is the type of seismic wave that moves like an accordion through the Earth.
What is a primary wave?
500
This is how chemical sedimentary rocks form.
What is by precipation of water leaving behind minerals?
500
This is a force that causes folding.
What is compression?
500
Slope and silica affect this.
What is the rate of lava flow?
500
This is the type of boundary that creates new ocean floor.
What is at a divergent boundary?
500
This type of seismic wave cannot travel through the liquid parts of the earth.
What is a secondary wave?
