CIA #4 Review (Earth's Structure)

Which of the following are components of the biosphere?

• bacteria

• air

• water vapor

• clouds

Which of the following statements is true of the four spheres of Earth?

• The hydrosphere and biosphere are closely linked, but the atmosphere and

  geosphere are not.

• The four spheres of Earth are very closely connected and a change in one

  often affects another.

• The geosphere, atmosphere, and hydrosphere are very co-dependent, but the

  biosphere is unrelated to the others.

• The four spheres of Earth are strictly independent entities and no interactions

  take place between them.

An alligator who lives in a swamp is an interaction between which of Earth's spheres

• biosphere and atmosphere

• hydrosphere and biosphere

• atmosphere and geosphere

• geosphere and biosphere

When volcanoes erupt, dust and ash particles spread through much of the air blocking the sun.  Which two spheres are interacting? 

• Hydrosphere and atmosphere 
• Geosphere and atmosphere 
• Biosphere and atmosphere 
• Atmosphere and atmosphere 

This diagram shows layers of Earth's structure. Place the layers in the correct order, from outside to inside, as shown by the

arrows.

• inner core -> outer core -> mantle -> crust

• mantle -> crust -> outer core ->inner core

• Crust -> Mantle -> Outer Core -> Inner core

• crust -> inner core

  -> mantle -> outer core

Why is the inner core made from solid metal, while the outer core is made of

molten metal?

• The temperature of the inner core is higher than the outer core

• The temperature of the inner core is lower than the outer core

• The pressure of the inner core is higher than the outer core

• The pressure of the inner core is lower than the outer core

Which layer of the Earth is made up of liquid iron?

• inner core

• outer core

• mantle

• crust

When rock particles settle at the bottom of the ocean, they can continue to be buried by other particles. The process of cementation of these particles forms 

• molten rock

• igneous rock

• sedimentary rock

• metamorphic rock

Which of the following best explains the interaction between the geosphere and

hydrosphere?

• Water accumulates and creates lakes.

• Water precipitates down on mountains and valleys.

• Water is evaporated out of oceans.

• Water shapes the physical landscape through weathering and erosion.

Place the processes in the formation of sedimentary rock in correct order.
