Density/Seismic Waves/Earth's Interior

Front

What is density?

Back

Density is the mass of an object divided by its volume, typically expressed in grams per milliliter (g/mL) or kilograms per cubic meter (kg/m³).

Front

What is the formula for calculating density?

Back

Density = Mass / Volume.

Front

What are seismic waves?

Back

Seismic waves are waves of energy that travel through the Earth, typically generated by earthquakes or other geological activity.

Front

What are the two main types of seismic waves?

Back

The two main types of seismic waves are body waves (P-waves and S-waves) and surface waves.

Front

What are P-waves?

Back

P-waves, or primary waves, are compressional waves that travel through solids, liquids, and gases. They are the fastest seismic waves.

Front

What are S-waves?

Back

S-waves, or secondary waves, are shear waves that can only travel through solids. They are slower than P-waves.

Front

What are surface waves?

Back

Surface waves travel along the Earth's surface and typically cause the most damage during an earthquake.

Front

What is the inner core of the Earth made of?

Back

The inner core is primarily composed of iron and nickel and is solid due to the immense pressure.

Front

Why is the inner core solid despite high temperatures?

Back

The inner core is solid because the pressure at the Earth's center is extremely high, preventing the iron and nickel from melting.

What happens to an object with a density less than water when placed in water?

Back

An object with a density less than water will float.
