The Inner Planets are Out of this World: The Inner Planets are Out of this World
Slide2: The sun is the center of the solar system. The energy from the sun, which is called solar energy, gives light and heat to the planets. The closer a planet is to the sun, the more light and heat it gets.
Slide3: Now… Onto the
Inner Planets
Slide4: The closest planet to the sun is Mercury. It is very small. A night on Mercury is much colder than the coldest night on Earth. A day on Mercury is much hotter than the hottest day on Earth. No living things could survive in such cold or such heat! It takes Mercury only 88 Earth days to travel once around the sun.
Slide5: The second planet from the sun is Venus. Venus is about as big as Earth. It also has mountains and plains like Earth. However, Venus is different from Earth in many ways. It is covered by thick clouds of acid. The clouds hold in the sun's heat, so it is very, very hot on Venus. It is too hot and dry there for plants or animals to live. It takes Venus 225 Earth days to travel once around the sun.
Slide6: Earth is the third planet from the sun. Almost three-fourths of Earth's surface is covered by water. Water allows plants and animals to live. As far as we know, no other planet has liquid water. Earth has one moon. It takes Earth 365 days -- one year -- to travel once around the sun.
Slide7: The fourth planet from the sun is Mars. It is smaller than Earth. Mars is much colder than Earth. Mars does not have blue patches of liquid water like Earth, but does have some ice that is solid water below its soil. Mars has ice "caps" like those at the North and South Poles of Earth on its surface. Mars has been nicknamed "the red planet, because it has red soil. Mars has at least 2 moons and takes 2 Earth years to travel once around the sun.
