Geologic Time
100

This layer is where all life is found. 

What is the crust?

100

This structure zone is all solid rock on the crust and top part of the mantle 

What is the lithosphere?

100

Lines of lontitude are called this. 

What are meridians?

100

These are the lines drawn on a topographic map. 

What is a contour line?
100

This measurment of time is tens of millions of years. 

What is an epoch?

200

This layer is the largest 

What is the mantle?

200

This structural zone is made from solid mantle rock 

What is the mesosphere?

200

Lines of latitude are called this

What are parallels?

200

This number represents the difference in elevation between contour lines. 

What is a contour interval?

200

This measurment of time is hundreds of millions of years. 

What is a period?

300

This layer is made from solid nickel and iron. 

What is the inner core?

300

This not quite solid, but not quite liquid layer is below the crust. 

What is the asthenosphere?

300

This imaginary line divides the earth into the eastern and western hemispheres

What is the prime meridian?

300

On a map, this shows where north is. 

What is a compass rose? 

300

This measurment of time includes billions of years. 

What is an eon?

400

This is the reason the inner core is solid, while the outer core is liquid. 

What is pressure?

400

The asthenosphere is found in which Earth layer?

What is the mantle?

400

This is the location at 90 degrees north 

What is the northpole?

400

These show a hole or a pit. 

What is hacture marks? (depression contour lines)

400

This is the geological time measurments from the shorest to the longest. 

What is epoch, period, era, and eon. 
500

This is all the layers of the Earth starting from the center of the Earth. 

What is inner core, outer core, mantle, and crust. 

500

The asthenosphere is responsible for these type of earth's movements. 

What is plate tectonincs? (Earthquakes, etc)

500

This is the maximum amount of degrees for longitude. 

What is 180?

500

A steep slope on a topographic map is shown by this. 

What are lines close together?

500

This is what determines a set of geologic time. 

What is major geologic events and fossils?
