1. The First Quarter Moon always occurs
Artemon [7]

Answer:

1.- b. when the Moon is at right angles to the direction of the Sun.

2.-b. when the Moon is directly opposite the position of the Sun.

3.-b. when the Moon is closer to the Sun than the Earth is.

Explanation:

  • The First Quarter Moon is when we can see exactly half of the Moon's surface illuminated. If it is the left or right half, it depends on where you are on Earth. If we observe the diagram I added we can see than <em>the moon is at right angles to the direction of the Sun</em> when it's in this phase.
  • Full Moon happens when<em> the Moon is on the opposite side of the Earth from the Sun</em>, this makes the bright side of the Moon face the Earth. This is also observable in the diagram.
  • The New Moon always occurs when <em>the Moon is between the Earth and the Sun, therefore it's closer to the Sun than the Earth</em>, the bright side of the Moon is facing away from the Earth. You can check this in the diagram as well.

I hope you find this information useful and interesting! Good luck!

Why do tropical zones have a hot and humid climate year round and polar zones have a cold climate year round?
Ivenika [448]
Tropical places are hot because the humidity coming from the moisture of the plants and water are heated by the sun on the top layer of the tropical zone. The climate varies little in rain forest. There are five layers in the tropic trees so it's so thick that barely any light come through. This is also why vines grow up the trees so they can reach the sunlight to get nutrients. Also, the tropics are near the equator and that also causes the heat. The polars are cold because they barely get any sun heat to melt the snow or warm it up. The polars are melting due to certain chemicals and gasses in the atmosphere. also known as global warming. Hope that was helpful!
