Questions: A scientist wishes to learn about volcanoes and earthquakes. Which of the following spheres should she most directly study? (2 points) Atmosphere Biosphere Cryosphere Geosphere

The answer is the fourth one (Geosphere): the original text in the question...

Explanation for each option:

• Atmosphere: This refers to the layer of gases surrounding the Earth. It is not directly related to the study of volcanoes and earthquakes.
• Biosphere: This encompasses all living organisms on Earth. While it can be affected by volcanic eruptions and earthquakes, it is not the primary sphere to study these phenomena.
• Cryosphere: This includes all the frozen water parts of the Earth, such as glaciers and ice caps. It is not directly related to the study of volcanoes and earthquakes.
• Geosphere: This includes the Earth's solid rocks and the processes that shape the Earth's surface, such as volcanic activity and tectonic movements, making it the most relevant sphere for studying volcanoes and earthquakes.

Summary: The scientist should most directly study the Geosphere to learn about volcanoes and earthquakes.
