How does the 4 subsystems of the Earth connect with each other?

• These subsystems interact with each other to influence the climate, trigger geological processes, and affect life all over the Earth.

• There is no connection in the four subsystems of the Earth.

• The subsystems of the Earth are called spheres because they are round, just like the Earth.

How have scientists been able to infer the internal structure of Earth without being able to directly observe inside the Earth?

• Scientists analyze how earthquake waves move through Earth's interior.

• Scientists use satellite radar and sonar technologies to map Earth's internal layers.

• Scientists make educated guesses about Earth's internal structure based on previous hypothesis.

• Scientists study different types of rocks from many different locations on Earth's surface.
