1) The phase of the Moon during a total solar eclipse is a new moon. In a solar eclipse, the Moon is in between the Sun and the Earth. The Moon blocks some sunlight creating a the Earth to become dark for a few minutes at specific locations. The phase of the Moon during a total lunar eclipse is a full moon. In a lunar eclipse, the Earth is in between the Sun and the Moon. The Earth blocks the Moon from the Sun. The Earth casts its shadow on the Moon, giving it a red color.

2) Earth’s core is spilt into two sections, the outer core and inner core. The liquid outer core is made up of iron, nickel, and perhaps sulfur. The solid inner core is made of iron and nickel. The mantle is made up of silicates. We know this because of seismic waves that are generated by earthquakes. The seismic waves move at a certain speed depending on the material which they travel through. …show more content…
Rocks were brought back from the Moon by the Apollo Astronauts. They applied the techniques to date rocks on Earth to the Moon rocks. Radioactive day was used to determine the age of the rocks. The radioactive atoms decay into daughter atoms. Therefore, the more daughter atoms there are the older the rock is. Radioactive elements with half-lives we have determined can help scientist get a more accurate nuclear clock. We have used this data to determine the age of the Moon as well as the Earth. They both formed about 4.5 billion years ago. We also concluded that colliding planetesimals formed the Earth’s moon. Earth and another body collided and the Moon formed from the left over
