Earth’s atmosphere is a mixture of nitrogen (79%), oxygen (20%), and a small fraction of carbon dioxide, water vapours and other gases. This makes the existence of life possible on Earth. However, the atmospheres on Venus and Mars mainly consist of carbon dioxide. The amount of carbon dioxide on these planets can range from 95% to 97%. This may be the reason no life exists on these planets.
The atmosphere of Venus is about 96 per cent carbon dioxide, with surface temperatures around 737 K (464 °C, or 867 °F).
Venus itself rotates only once every 243 Earth days.
Mars, in contrast, has a thin atmosphere composed of about 95 per cent carbon dioxide, with the remainder being mostly diatomic nitrogen.
Hey there!
The thin layer on Earth’s surface would be the CRUST.
Hope this helps!
<span>The answer is spin clockwise.
</span>In the northern hemisphere, gyres spin clockwise due to Coriolis effect. Coriolis effect is the effect of the Earth's rotation on the oceans and atmosphere. It is the cause of deflection to the right in the northern hemisphere and to the left in the southern hemisphere. Thus, in the northern hemisphere, gyres spin clockwise, and in the southern hemisphere, they spin counter-clockwise.<span>

Answer:
The geocentric model of the solar system has Earth at the center.
Explanation:
Throughout history, there have been multiple different models that humans thought of or created through observation. The two most famous ones from the past are the geocentric and heliocentric, with the geocentric coming earlier and for a very long time being the model that was accepted by the majority.
The geocentric model is a model that puts Earth in the center of the universe. Earth is presented as the most important and largest object in the universe. All of the space bodies, the Sun, stars, Moon, planets, were thought to revolve around Earth. As it turned out, this model was full of mistakes. Everything about it was wrong, with the only correct thing being that the Moon is actually revolving around Earth.
Answer: The period known as classical antiquity began with the emergence of the city-states of ancient Greece. Later, the Roman Empire came to dominate the entire Mediterranean basin. The fall of the Roman Empire in AD 476 traditionally marks the start of the Middle Ages.
