Earth History Volcanoes Earthquakes Plates

Earth's Layers

100

This is the outer most layer of the earth and is where we live. 

What is the crust 

200

These are the two types of crust 

What are oceanic crust and continental crust 

300

this layer of the earth is semisolid, and its movement causes the movement of the tectonic plates 

what is the mantle 

400

this is the inner most layer of the earth 

inner core 

500

this is the third layer of the earth 

what is the outer core 

rocks

100

this is melted rock with in the earth's crust 

what is magma

200

this type of rock is formed by magma cooling 

what is igneous 

300

this type of igneous rock has crystals 

what is intrusive 

400

this type of igneous rock does not have crystals

what is extrusive 

500

this is the difference between intrusive and extrusive 

what is intrusive forms inside the earth's crust and extrusive forms outside of the earth's crust 

earthquakes

100

this is the layer of the earth where most earthquakes occur 

what is the crust 

200

this is the line or part of the earth's crust where most earthquakes happen 

what is plate boundaries 

300

this is what causes earthquakes to happen 

what is tectonic plates moving and interacting with each other

400

this is what causes the tectonic plates of the crust to move 

what is convection in the mantle 

500

this is the term used to identify the strength of an earthquake 

what is magnitude 

volcanoes

100

this is the line or area of earths crust where most volcanoes occur 

what is plate boundaries 

200

this is the type of rock that you will mostly find near volcanoes 

what is igneous 

300

this is the hot molten rock that comes from volcanoes 

what is magma 

400

This island is made from erupting volcanoes 

What is Hawaii 

500

This is the reason volcanoes occur near fault lines

what is the plates hit together causing the rock t melt and form volcanoes

Crust

100

these are the large chucks that the crust is broken into 

what are plates

200

there are only plates on the continents not the ocean (true or false) 

false 

300

this is the mega continent that is believed to be the starting point of today's continents  

what is Pangea 

400

this happens when two plates interact with each other 

what is earthquake or volcano 

500

this is the evidence Wegener had to prove Pangaea was real.

what is fossils found on different continents, the continents seemed to fit like a puzzle, and glacier markings
