Earth's Interior new review

Front

What is the outer core of the Earth composed of?

Back

The outer core is composed of liquid material, primarily iron and nickel.

Front

What evidence supports the theory that the outer core is liquid?

Back

Seismic studies indicate that shear waves do not pass through the outer core, suggesting it is liquid.

Front

Which color of visible light has the shortest wavelength?

Back

Violet has the shortest wavelength among visible light colors.

Front

What zone of the Earth has the greatest density?

Back

The inner core has the greatest density of all Earth's layers.

Front

List the four planets of the solar system in order from smallest to largest.

Back

Neptune, Uranus, Saturn, Jupiter.

Front

What happens to objects with a density greater than water?

Back

Objects with a density greater than water will sink.

Front

What is the density of water in g/cm³?

Back

The density of water is approximately 1 g/cm³.

Front

How does density affect whether an object floats or sinks?

Back

An object will float if its density is less than the fluid it is in; it will sink if its density is greater.

Front

What is the primary composition of the Earth's inner core?

Back

The inner core is primarily composed of solid iron and nickel.

Front

What is the difference between shear waves and compressional waves?

Back

Shear waves cannot travel through liquids, while compressional waves can travel through both liquids and solids.
