crust
Which Earth system includes the layer of gases that surrounds Earth?
Atmosphere
Name the landform that is a large area of low relief and low elevation.
Plain
What force pulls material together and was responsible for the formation of the Earth?
Gravity
_______________________ is the height above sea level.
Elevation
Which layer is composed mostly of solid rock and lies directly beneath the crust?
Lithosphere/Mantle
Which Earth system includes all of Earth's solid materials (rocks, soil, landforms)?
Geosphere
Which topographic feature can be formed by tectonic uplift or volcanic activity and has HIGH elevation and LOW relief?
Plateau
What two factors affect the strength of gravity?
Mass and distance
The _______________________ is under so much pressure that it is liquid metal.
Outer core
Which layer is composed of molten (liquid) iron and nickel and lies outside the inner core?
Outer Core
Which Earth system includes all liquid water on Earth?
Hydrosphere
What term describes the surface shape and features of the land?
Topography
What happens to temperature as you go deeper into Earth?
it increases
The type of crust under the ocean is called __________________ and is more _____________________ than continental crust.
Oceanic/dense
Which layer is the very center of the Earth and is solid despite very high temperature?
Inner Core
Which Earth system includes all living organisms?
Biosphere
Which layer of the mantle is plastic-like and allows tectonic plates to move ?
Asthenosphere
What happens to pressure and density (usually) as you go deeper into Earth?
they increase
The _______________________ includes the crust and uppermost mantle.
Lithosphere
Which two elements make up most of the Earth's core?
Iron (Fe) and Nickel (Ni)
Match these descriptions to systems: a) layer of gases, b) all living organisms, c) Earth's entire solid body, d) liquid water on Earth
