THE MOONS SURFACE
1. Craters The surface of the Moon is covered
with craters that vary in size from small pits to
giant basins more than 200 km across. Because the
Moon with no atmosphere to protect its surface,
all objects hurtling toward it make a deep impact.

of molten lava. They were caused by huge flows of
lava from volcanoes. Now they are solid plains of
hardened lava.
