Earth's Layers
This layer is where all life is found.
What is the crust?
This structure zone is all solid rock on the crust and top part of the mantle
What is the lithosphere?
Lines of lontitude are called this.
What are meridians?
These are the lines drawn on a topographic map.
This measurment of time is tens of millions of years.
What is an epoch?
This layer is the largest
What is the mantle?
This structural zone is made from solid mantle rock
What is the mesosphere?
Lines of latitude are called this
What are parallels?
This number represents the difference in elevation between contour lines.
What is a contour interval?
This measurment of time is hundreds of millions of years.
What is a period?
This layer is made from solid nickel and iron.
What is the inner core?
This not quite solid, but not quite liquid layer is below the crust.
What is the asthenosphere?
This imaginary line divides the earth into the eastern and western hemispheres
What is the prime meridian?
On a map, this shows where north is.
What is a compass rose?
This measurment of time includes billions of years.
What is an eon?
This is the reason the inner core is solid, while the outer core is liquid.
What is pressure?
The asthenosphere is found in which Earth layer?
What is the mantle?
This is the location at 90 degrees north
What is the northpole?
These show a hole or a pit.
What is hacture marks? (depression contour lines)
This is the geological time measurments from the shorest to the longest.
This is all the layers of the Earth starting from the center of the Earth.
What is inner core, outer core, mantle, and crust.
The asthenosphere is responsible for these type of earth's movements.
What is plate tectonincs? (Earthquakes, etc)
This is the maximum amount of degrees for longitude.
What is 180?
A steep slope on a topographic map is shown by this.
What are lines close together?
This is what determines a set of geologic time.
What is major geologic events and fossils?
