How do scientists know the structure of the interior of the earth?

scientists have drilled a hole deep in the earth to the mantle.

scientist have used telescopes to record data about the earth's layers.

scientists use seismic waves and how they move through the earth.

Scientists use seismic waves and how they move through the Earth.

Explanation:

The core was discovered in 1936 by monitoring the internal rumbles of earthquakes, which send seismic waves rippling through the planet. The waves, which are much like sound waves, are bent when they pass through layers of differing densities, just as light is bent as it enters water.

The correct answer is: the third option: Scientists use seismic waves and how they move through the Earth.

Explanation:

Hello! Let's solve this!

Scientists have investigated the structure of the center of the earth, using earthquakes for it.

When an earthquake strikes, it produces many seismic waves. These waves are observed by scientists and recorded with their tools. From them they can know what is in the center of the earth and in each of its layers.

We conclude that the correct answer is: the third option: Scientists use seismic waves and how they move through the Earth.

lysosomes contain a variety of enzymes, enabling the cell to break down various biomolecules it engulfs, including peptides, nucleic acids, carbohydrates, and lipids (lysosomal lipase). the enzymes responsible for this hydrolysis require an acidic environment for optimal activity. hope i !
