Earth's Layers
The outermost layer of the earth
What is the crust?
The study of earthquakes
What is seismology?
Sheets of rocks that include part of the Earth's crust
What are plates?
Thick liquid that resists flowing, such as magma
What is viscous?
I consist of rocks, sand and soil. I am also all the layers of the Earth.
What is the geosphere?
Plates that are moving towards each other and meet, often forming mountains
What is a convergent boundary?
The smell of rotten eggs, an increase in heat, and newly formed smoke are all signs of this
What is a volcanic eruption?
People who are trained to work in any of the geologic sciences are called.
What is a geologist?
A series of ocean waves often triggered by an underwater earthquake
What is a tsunami?
Areas around the edge of the Earth's plates
What are boundaries?
An explosive hot rising column of magma
What is a plume?
All living things on Earth
What is the biosphere?
At a convergent boundary, one plate may move under another plate, which is also where many volcanoes form
What is a subduction zone?
This current carries heat energy from one location to another within a fluid (Hint: they are located in the mantle)
What is a convection current?
The center part of the Earth, composed of iron and nickel
What is the core?
The point underground where the rocks break and the earthquake begins
What is the focus?
Crustal plates move and float on this
What is the mantle?
A scientist who studies volcanoes
What is a volcanologist?
Gases that surround the Earth, such as oxygen and ozone
What is the atmosphere?
When two plates are sliding past each other
What is a transform boundary?
Observations and reasoning lead to making these (Hint: You make these in ELA)
What is an inference?
All magma comes from here
What is the mantle?
A devise used to measure the strength of earthquakes
What is a seismograph?
A continuously growing mountain range located under the oceans
What is the mid-ocean ridge?
The release of material from under the Earth's crust rising to and breaking through the surface
What is a volcanic eruption?
Icebergs and glaciers
What is the cryosphere?
At transform boundaries, the stress of sliding past one another often causes these
What is an earthquake?
According to this theory the Earth is made of plates that interact with each other
What is the theory of plate tectonics?
The rigid part of the Earth made up of the crust and solid uppermost part of the mantle
What is the lithosphere?
The magnitude of an earthquake measures its?
What is strength?
Areas in the middle of plates where hot plumes of magma form volcanoes
What is a hot spot?
A volcano that is currently erupting or soon expected to erupt
What is an active volcano?
All water, including lakes, oceans, ponds and rivers
What is the hydrosphere?
This is a force that 1) squeezes rocks together 2) pulls rocks apart and 3) pushes rocks in different directions. (Hint: You may cause this for all your teachers...)
What is stress?
We are all going to score this on our test
What is 100?
