What Are The Two Main Ways Scientists Learn About Earth's Interior?

Plate Tectonics There are two main ways scientists learned about Earth’s interior. During earthquakes, seismic waves form, in which scientists use. For example, seismic waves travel through earth by speed and path that travel through earth. They study how seismic waves travel through Earth by how fast and which path it goes. The second main way is the rock samples are very useful that are drilled and scientists looked at rocks that came to the surface. An example of this is that they drilled into the earth and found rocks that came to the surface. In conclusion, scientists study about the earth’s interior by using two main ways.

Crust, Mantle, Core There are three main layers of earth, the crust, mantle, and core. The first main layer is the crust which is the outer

The first type of evidence Alfred Wegener found was land features. For example, he found coal fields in North America and Europe line up. He also found mountain ranges in South America and Africa line up and he attempted to put the continents together like a puzzle. The second type of evidence Alfred Wegener found was fossils. An example of this is that he found a fern like plant called Glossopteris that he found in rocks in Africa, South America, Australia, India, and Antarctica. He found the Mesosaurus and Lystrosaurus fossils which were found on continents separated by oceans. The last type of evidence Alfred Wegener found was climate zones. An example in the textbook is that he studied fossils and rocks and looked for evidence of past climates. He found an island in the Arctic which is called Spitsbergen which once had a warm climate. He also found tropical plant fossils. He found out that South Africa has a warm climate. In glaciers, he found scratches in rocks from glaciers. In conclusion, the three types of evidence Alfred Wegener found was land features, fossils, and climate
