Front

What is sea floor spreading?

Back

Sea floor spreading is the process by which new oceanic crust is formed at mid-ocean ridges as magma rises from the mantle, causing the ocean floor to expand.

Front

What causes sea floor spreading?

Back

Convection of heat within the mantle results in less dense magma rising at mid-ocean ridges, building new sea floor.

Front

What would happen to planets without the Sun's gravity?

Back

The planets would drift away from the Sun into outer space.

Front

What is the role of gravity in planetary motion?

Back

Gravity from the Sun keeps the planets in orbit, preventing them from drifting into space.

Front

What does a tornado data graph show?

Back

A tornado data graph displays the frequency and intensity of tornado occurrences over a specified period.

Front

What can be inferred from tornado data showing less frequency in the morning?

Back

Back

Condensation is the process by which water vapor cools and changes into liquid water.

Front

What is the importance of detailed records in scientific investigations?

Back
