Question

1. asteroids and volcanoes were responsible for which of the following phenomena?

○ cooling the earth by cycling it through warm and cold
○ shaping our oceans by creating more islands
○ changing the atmosphere
○ changing the earths rotation

Explanation:

Asteroid impacts release dust/gases, and volcanoes emit gases (e.g., CO₂, sulfur) that alter atmospheric composition. The other options are incorrect: Earth's cooling cycles relate to orbital changes, island formation is mainly from tectonic activity, and Earth's rotation change requires massive forces not typical of these events.

Answer:

changing the atmosphere
