EAS SEM A 2023 Final Exam/Semester Test Review

Front

What force pulls planets into a curved path when they are orbiting the sun?

Back

Gravity is the force that pulls planets into a curved path around the sun, keeping them in orbit.

Front

Which layer is farthest from Earth's center?

Back

The lithosphere is the outermost layer of the Earth, farthest from its center.

Front

At which continental feature would you expect to find metamorphic rock?

Back

Metamorphic rock is typically found in mountains, where intense pressure and heat cause the transformation of existing rock.

Front

What does it mean to say that objects in our solar system have eccentric orbits?

Back

Eccentric orbits refer to orbits that are slightly oval-shaped rather than perfect circles.

Front

What is the order of the flow of energy from its production within the sun until it reaches Earth?

Back

The order is: nuclear fusion; radiation; convection currents; radiation.

Front

Define nuclear fusion.

Back

Nuclear fusion is the process by which two light atomic nuclei combine to form a heavier nucleus, releasing energy.

Front

What is the lithosphere?

Back

The lithosphere is the rigid outer layer of the Earth, consisting of the crust and the upper mantle.

Front

Explain the concept of convection currents in the Earth's mantle.

Back

Convection currents are the movement of molten rock in the mantle caused by heat from the Earth's core, driving plate tectonics.

Front

What is the difference between the inner core and outer core of the Earth?

Back

The inner core is solid and composed mainly of iron and nickel, while the outer core is liquid and also made of iron and nickel.

Front

What is an example of a continental feature formed by tectonic activity?

Back

Mountains are a common example of continental features formed by tectonic activity, such as the collision of tectonic plates.
