Question

10 multiple choice 2 points seasons are caused by... earths rotation on its axis. earths revolution on its axis. the tilt of earth on its axis the tilt of earth on its rotation 11 multiple choice 2 points which sphere of earth covers approximately 70% of earths surface? atmosphere lithosphere hydrosphere asthenosphere

Explanation:

• For question 10: Earth's rotation on its axis causes day - night cycle. Earth's revolution is around the Sun, not on its axis. The tilt of Earth on its axis is the main cause of seasons as it affects the angle and intensity of sunlight received at different times of the year.
• For question 11: The atmosphere is the layer of gases around Earth. The lithosphere is the rigid outer part of Earth. The hydrosphere includes all water on Earth (oceans, lakes, etc.) and covers about 70% of Earth's surface. The asthenosphere is a semi - molten layer beneath the lithosphere.

Answer:

1. The tilt of Earth on its axis
2. hydrosphere
