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!

What are spacecrafts called?</h3>
- The following are the main distinctions between rockets and spacecraft: The spacecraft is propelled into orbit by rockets before returning to earth.
- Although spacecraft can be either manned or unmanned, rockets are always unmanned. Additionally, spacecraft lack the power that rockets possess.
- Although not all satellites can be spacecraft, all spacecraft can be satellites.
- An object that orbits the Earth, the moon, or another celestial body is referred to as a satellite, whereas a spacecraft is a vehicle or technology designed for travel or operation outside the Earth's atmosphere.
- A device built to go across space is called a spaceship. They are capable of being utilized for Earth observation, communication, navigation, and space exploration.

Answer: Coastal Recession / Erosion
Explanation:
An Estuary is that part of the river that is semi closed and yet mixes with the sea or ocean.
Research has shown that rivers that have Dams built on them have led to rapid coastal erosion. This is because rivers usually carry sediments of SA and other particles with them but these sediments will instead be trapped by the dam instead of being deposited at the Estuary.
This Coastal erosion is a problem because it leads to serious Environmental problems such as the loss of habitat for some organisms, the loss of Coastal protection, loss of biodiversity as well as the reduction in livelihood of people living in Estuarine environments.
