Astronomy simple Q
Answer the Q simply.

1. Explain why a high tide occurs on the side of Earth opposite the Moon. On the side of Earth near the Moon, why is high tide not directly under the Moon?

2. Describe one of the methods astronomers use to detect exoplanets. What type of planet can this method most easily detect (for example, what size, mass, distance
from star)?

3. When they formed, Venus and Earth probably both had thick, carbon dioxide rich atmospheres. Today the atmospheres of Venus and Earth are very different even though
their sizes and masses are quite similar. Describe how most of the CO2 from Earth’s early atmosphere was removed. Where is all that CO2 today?

4. Heat in the interior of the Jovian planets drives convection in the planets’ atmospheres. The Jovian planets also have strong jet streams that circle the planets.
Describe how convective motion is converted into strong jet streams. Draw a picture showing how this occurs. What is a consequence of fast jet streams moving in
opposite directions next to each other?
