Scientist learn about the earth's interior by studying?

Answer 1

Scientist learn about the earth's interior by studying seismic waves. 'P' waves travel all the way through Earth's crust, mantle, outer and inner core and give scientists a glimpse of the interior.

Answer 2

Geologists learn about the Earth's interior by studying seismic waves. As the waves pass through the Earth's layers, inferences about the composition and temperature of these layers are made, based on the velocities of the waves.

Answer 3

If scientists have never studied any materials from a depth below 7 miles, then how is it that we know what is in the center of the Earth? How can we know what the core of the Earth is made of, if we have never seen it?

The answer is actually quite simple. While it is true that we can not study the Earth's core using visible light, we can study it using other senses. The most important thing we use to sense the Earth's core are seismic waves. Seismic waves are waves of energy caused either by earthquakes, or by massive manmade explosions.

Scientists are able to measure these waves as they pass through the Earth. As these waves encounter different materials, they change in important ways, becoming longer, shorter, faster, or slower. Geologists study these changes in the waves, and are able to draw conclusions about what the core of the Earth must look like.

Geologists also can learn a lot about the core of our planet by looking at Earth's magnetic field. The Magnetic field is created by massive circulations of hot liquid mantel beneath the Earth's surface.

So to simplify Seismic waves and The Earth's Magnetic Field

Answer 4

They use seismic waves

Answer 5

Scientists study the interior of earth by analyzing seismic waves, which are linked energy waves like sound, light and water waves.

Answer 6

"sound waves"

Answer 7

how geologists now about the interior earth
