Question
How would studying a volcanic eruption help you investigate cooler temperatures on Earth?(1 point)
Responses
Volcanic eruptions eject tsunamis, which reflect incoming energy from the sun back to space, therefore cooling the surface of Earth.
Volcanic eruptions eject tsunamis, which reflect incoming energy from the sun back to space, therefore cooling the surface of Earth.
Volcanic eruptions eject sulfur dioxide, which is converted to sulfuric acid, which then reflects incoming energy from the sun back to space, therefore cooling the surface of Earth.
Volcanic eruptions eject sulfur dioxide, which is converted to sulfuric acid, which then reflects incoming energy from the sun back to space, therefore cooling the surface of Earth.
Volcanic eruptions eject water vapor, which reflects incoming energy from the sun back to space, therefore cooling the surface of Earth.
Volcanic eruptions eject water vapor, which reflects incoming energy from the sun back to space, therefore cooling the surface of Earth.
Volcanic eruptions eject carbon dioxide, which reflects incoming energy from the sun back to space, therefore cooling the surface of Earth.
The correct answer is: Volcanic eruptions eject sulfur dioxide, which is converted to sulfuric acid, which then reflects incoming energy from the sun back to space, therefore cooling the surface of Earth.

The correct answer is: broken coral reefs
The Earth can be divided into four main spheres: the biosphere, lithosphere, hydrosphere, and atmosphere. To distinguish between these spheres, we need to understand their characteristics and composition.
The biosphere refers to all living organisms on Earth, including plants, animals, and microorganisms. It encompasses all parts of the planet where life can exist, such as the surface of land, bodies of water, and even the atmosphere where birds and insects fly.
The hydrosphere comprises all of Earth's water, including oceans, seas, lakes, rivers, groundwater, and even water vapor in the atmosphere. It is often referred to as the "water sphere" because it represents all the water on the planet.
The atmosphere is the layer of gases that surround the Earth. It consists of a mixture of nitrogen, oxygen, carbon dioxide, and other trace gases, as well as water vapor. The atmosphere plays a crucial role in regulating the planet's climate, weather patterns, and protecting life from harmful solar radiation.
Finally, the lithosphere refers to the solid outer layer of the Earth. It includes the crust and the uppermost portion of the mantle. The lithosphere is composed of solid rock and minerals and is divided into several tectonic plates. It covers the entire Earth's surface, extending from the depths of the oceans to the top of the highest mountains.
Now, to determine which sphere contains solid rock both below and at Earth's surface, we can eliminate the biosphere and hydrosphere because they mainly consist of living organisms and water. The remaining option is the lithosphere, which is composed of solid rock both below the surface (the mantle) and at the Earth's surface (the crust).
Therefore, the correct answer is: lithosphere.
