Geosphere (E.7A)

The GEOSPHERE starts at the ground and extends all the way down to earth's core. We rely on the geosphere to provide natural resources and a place to grow food. Volcanos, mountain ranges, and deserts are all part of the geosphere. Without the geosphere, there would be no Earth!

What does the prefix "geo" mean?

• soft

• stone

• ground

• life

The Earth's geosphere is divided into three main sections - Check ALL that apply ...

• mantle

• crust

• core

• atmosphere

The LITHOSPHERE is the rigid outer part of the earth’s crust and upper mantle, divided into tectonic plates. Collisions and separations of the plates result in landforms.

What does the prefix "litho" mean?

• stone

• soft

• ground

• life

The ASTHENOSPHERE is the upper layer of the earth's mantle, below the lithosphere, much hotter and more fluid than the lithosphere. Convection currents in the asthenosphere move tectonic plates.

What does the prefix "astheno" mean?

• stone

• soft

• ground

• life

The hard outer layer of Earth, composed of different types of solid rocks is called the -

• outer core

• inner core

• mantle

• crust

That is hot and mostly-solid bulk of Earth’s interior, that is made up of silicate rocks and other elements -

• outer core

• inner core

• mantle

• crust

Part of the geosphere that is mostly composed of liquid iron and nickel and is very hot. It is easily deformed and malleable -

• outer core

• inner core

• mantle

• crust

Part of the geosphere that is a hot, dense ball of (mostly) iron -

• outer core

• inner core

• mantle

• crust

What are the two types of Earth's crust?

• continental

• oceanic

• atmospheric

• biotic

In which part of Earth's geosphere do convection currents, due to the heat coming from the core, drive plate tectonic movement and contribute to volcanoes, seafloor spreading, earthquakes, and orogeny (mountain-building)? 

• crust

• mantle

• outer core

• inner core
