Question

After its formation, early earth experienced several crucial events that were responsible for creating its spheres. Match each Precambrian event to the sphere it played the biggest role in creating. Which sphere was created by frequent volcanic eruptions emitting large amounts of carbon dioxide, followed by clouds forming and rains, and then molten lava solidifying into a solid crust?

Answer 1

The Precambrian period featured significant volcanic activity, which released gases such as CO₂ into the atmosphere and played a crucial role in the creation of Earth's geosphere, particularly the solid crust.

Step-by-step explanation:

The event described involving volcanic eruptions emitting large amounts of carbon dioxide and subsequent cooling and solidification processes played the biggest role in creating Earth's geosphere.

During the Precambrian period, frequent volcanic eruptions were a significant source of gases like CO₂, which contributed to the formation of Earth's early atmosphere. This atmosphere helped cool the planet, leading to the formation of water clouds, rain, and eventually, oceans once temperatures became low enough. The cooling of Earth and the establishment of solid ground from molten lava led to the creation of Earth's solid crust, a key component of the geosphere.

As the crust solidified, plate tectonics began to shape the earth's surface, contributing to the creation of the continents and ocean basins. This geologic activity, including volcanic eruptions and cooling of the Earth's surface, was crucial in establishing the geosphere, which is the solid, rocky shell of our planet.

It contains all of the crust and the outer portion of the mantle and is where most recognized geologic activity, including earthquakes and volcanic eruptions, occurs.
