Description
"What's inside the Earth" PPT
Part One: Exploring the Earth
Exploration: What’s inside the Earth?
Human exploration of the Earth’s interior
It is about 6,400 kilometers from the ground to the center of the earth, and the most advanced drilling rigs can only drill to a depth of more than a dozen kilometers. If the earth is compared to an apple, it is equivalent to not even drilling through the skin.
How can we know what’s going on inside the earth?
Seismic waves can propagate in all directions, and some can reach all the way to the center of the earth. When seismic waves encounter different materials during propagation, they will be reflected and refracted differently. By recording this information with instruments, and then conducting analysis and research, you can know the state and distribution of underground materials.
Scientists use information provided by seismic waves, magnetism, etc. to explore and study the internal conditions of the earth.
