Front

How do mountains form?

Back

Mountains form when converging plates collide, buckling and forcing rock from inside Earth to rise. This process can continue, allowing mountains to grow, such as the Himalayans.

Front

What is the result of pulling an object with 50 N to the right and 110 N to the left?

Back

The net force is 60 N to the left.

Front

What type of force is present when two sides in a tug of war pull with equal force?

Back

This is an example of balanced forces.

Front

Identify three ways convection occurs on Earth.

Back

Convection occurs in the oceans as currents, in the atmosphere as wind, and in the mantle as magma currents.

Front

What is the difference between weather and climate?

Back

Weather refers to short-term atmospheric conditions, while climate refers to long-term patterns of temperature and precipitation in a region.

Front

What is sedimentary rock?

Back

Sedimentary rock is formed from the accumulation and compaction of mineral and organic particles.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by natural processes such as wind or water flow.

Front

What is deposition?

Back

Deposition is the geological process where material is added to a landform or land mass.

Front

What is the role of magma in mountain formation?

Back

Magma can push up through the Earth's crust to form volcanic mountains.

Front

What is a balanced force?

Back

A balanced force occurs when two forces acting on an object are equal in size but opposite in direction, resulting in no change in motion.
