Answer:

The early atmosphere was comprised of a high amount of carbon dioxide and water vapor. These water vapors have undergone the process of condensation and resulted in the formation of oceans. The carbon dioxide gas was mostly consumed by primitive lives such as the blue-green algae, and cyanobacteria, and by carrying out the process of photosynthesis, it liberated oxygen.

Some amount of carbon dioxide was also brought down from the atmosphere by mixing up with the rainwater (acid rain), and are mostly concentrated in the deeper zone of the oceans forming limestones.

Currently, a total of about 0.03% of CO₂ is present in the atmosphere in today's world.

Describe the position of the sun when an equinox is experienced​
damaskus [11]

Answer:

At the equator, the sun is directly overhead at noon on these two equinoxes. The "nearly" equal hours of day and night is due to refraction of sunlight or a bending of the light's rays that causes the sun to appear above the horizon when the actual position of the sun is below the horizon.

Hope this helps!!!

Have a blessed day:)

Love you alllllll

The earth is closer to the sun during summer in the northern hemisphere than it is during winter.
Nataly_w [17]
Salutations!

The Earth is closer to the sun during summer in the Northern Hemisphere than it is during winter. True or False?

True. The Earth is closer to the sun because during the summer, the sun rays are directly hitting towards the Northern Hemisphere which makes it hot. During the winter, the sun rays are not directly hitting, thus, its cooler in winter than in the summer.

Hope I helped :D
