Answer to Question 1

Composite volcanoes form above subduction zones where the descending crust melts and the magma rises to the surface. This forms chains of volcanos along the subduction zone. A shield volcano is formed by a highly fluid lava that flows easily and creates low-profile volcanic peaks with slopes of 3 to 10 degrees.

Answer to Question 2

Liquid water cannot survive on the surface of Mars because the air pressure is too low. Any liquid water would immediately boil away; and if you stepped out of a spaceship on Mars without your spacesuit, your body heat would make your blood boil. A further problem is that Mars has no ozone layer to protect its atmosphere from ultraviolet radiation.
