Short Answer Questions:
(26.)
Compare the temperatures, thicknesses, and compositions of Earth’s, Venus’, and Mars’
atmospheres.
Earth's atmosphere is about 4/5 nitrogen and 1/5 oxygen. Venus atmosphere is mostly carbon
dioxide with a pressure about 90 times higher than earth. Mars atmosphere is also mostly carbon
dioxide with a pressure only about 100th that of earth.
(27.)
Describe two ways that Mars is similar to Earth and two ways that Mars is different from
Earth.
Earth is much larger Denser and heavier than Mars earth also has a stronger gravitational pull and a
thicker atmosphere. Mars is much colder than earth and has a longer orbit around the sun.
(28.)
Describe two characteristics of Venus that make it extremely hostile to Earth life.
Venus has no surface water. The atmosphere is also very heavy and almost entirely made up of
carbon dioxide which would be very hostile to the life we have on earth.

Your friend tells you that a Total Solar Eclipse can only happen when the Moon is in a New
Moon phase. Explain why your friend is correct or incorrect.
A total solar eclipse can only occur during a new moon when the sun is between the earth and sun.
This would make my friend correct.
(30.)
Describe at least three differences between the Moon's maria and highlands.
Maria is the solidified lava and contains a high density which produce a darker color. The highlands
are light colored areas above the Maria. The highlands are largely made of low density rocks rich in
aluminum. The highlands are much older than the Maria and are heavily cratered.
