Question 1
• The pressure at the surface of Venus is about 90 atmospheres, or 90x the pressure at Earth sea level.
• It receives about twice the amount of solar energy as the Earth.
• The clouds of Venus are made from sulfuric acid droplets.
• The temperature at the surface is remarkably close to that of the Earth, about 300 K.
• It is rotating in the opposite direction of the other planets, also called a retrograde rotation.
Question 2
Surface area
Question 3
Yes
Question 4
Its iron core has cooled and is completely solid now.
Question 5
carbon dioxide, CO2
Question 6
gentle flows from a plume or upwelling magma, along the very flat surface.
Question 7
The hydrogen and helium that is found near the surface, is probably being emitted through volcanic vents on the surface.
Question 8
• They all have an iron core, silicate mantle and crust.
• They all have roughly the same size mantles in comparison to their cores.
Question 9
phosphine, PH3
Question 10
• cratering
• weathering
• differentiation
Part B
Question 1
earth
Question 2
Yes, because Mars has an axial tilt of about 25 degrees.
Question 3
underground liquid “lakes” of water
Question 4
1% of Earth’s pressure at the surface, and composed almost entirely of CO2
Question 5
It was absorbed by the ocean water. This is why the ocean has bubbles in it.
Question 6
it will be smaller
Question 7
In mythology, Mars is the god of war and his sons were Deimos, the god of dread, and Phobos, the god of fear.
Question 8
Bugs Bunny found the Martian in the cartoons.
Question 9
primarily carbon dioxide (CO2) ice at the surface and water (H2O) ice beneath the surface
Question 10
They are not massive enough for their gravitational force to pull them into the shape of a sphere.
