Earths Surface

• How do we know what Earths surface looks like?

Astronaut

• An astronaut is a person who travels in space to
  explore.
• On July 2, 1969,Neil Armstrong and Edwin Aldrin
  were the first two people to walk on the moon.
• Scientists have studied rocks and photographs
  these astronauts brought back.

4
Stars

• A star is a big ball of hot gases which give off
  light.
• How bright a star is depends on . . .
• - the size of the star
• - how hot the star is
• - how close the star is to Earth

5
Why do people in the cities see fewer stars than
people who live in the country?

• There are too many lights in the city. These
  lights prevent people from seeing thousands of
  stars each night.

6
Constellations

• A constellation is a group of stars that form a
  star picture.

7
Sun

• The sun is the closest star to Earth.
• The sun is a big ball of hot gases.
• The sun gives off two kinds of energy light and
  heat. This is called solar energy.
• The sun never moves.
• All nine planets orbit, or move, around the sun.
• The sun is so large that more than a million
  Earths could fit inside it.

8
With out the sun, there would be no life. Why?

• Plants use the suns light to make food.
• Animals and people use the suns light to see in
  the daytime.
• Plants and animals need light and heat to live
  and grow.
• The suns heat warms water, land, and air.
• The suns heat warms all living things on Earth.
• All the other planets go around the sun, too, but
  Earth is the only planet where we can live. The
  sun gives us just the right amount of heat and
  light.

9
Planet

• A planet is a large ball of rock or gas that
  follows a path round the sun.
• There are nine planets.

Sun ? Mercury, Venus, Earth, Mars, Jupiter,
Saturn, Uranus, Neptune, Pluto ( My Very Eager
Mother Just Served Us Nine Pizzas! )
10
The solar system includes the sun and nine
planets.
11
Earth

• Earth is the planet that we live on. It is the
  3rd planet from the sun.It is called a Rocky
  Planet, because it is made of rocks.
• Sometimes Earth is called the Water Planet,
  because it is the only planet with the water we
  need to live.
• Earth orbits, or circles, the sun in 365 days, or
  one year.
• While it is orbiting the sun, it also spins like
  a top! It spins 1 time in 24 hours, and that is
  why Earths day lasts for 24 hours.
• Earth is the only planet where plants and animals
  live

12
Earth has day and night.

• Rotation is when something spins round in round.
• It takes about 24 hours for the Earth to rotate,
  or spin. This is one full day.
• This rotation causes the Earth to have day and
  night.

Seasons

• A season is a time of year that has a certain
  kind of weather.
• - winter, spring, summer, and fall (autumn)
• Earth follows a path around the sun. This path is
  called an orbit.
• As the earth moves around the sun, Earth has
  different seasons.
• The sun shines on different parts of the Earth
  at different times which cause the seasons.

14
Revolution

• Remember that the Earth is tilted all the time
  that it is moving around the Sun.
• It takes the Earth one year to move around the
  sun. This is called a revolution. It follows an
  orbit, or path.

15
The Moon

• The moon is the largest object you can see in
  the night sky.
• The Earth has one moon. The moon travels around
  the Earth. It takes the moon about 4 weeks, one
  month, to travel around the Earth.
• A crater is a hole, valley, or indentation on a
  planet or moon made by a large rock.
• There is no life on the moon because there is no
  air.
• Moonlight is the light of the moon. This light
  comes from the sun. Which part of the moon is
  lighted by the sun?
• - The part of the moon that is facing the sun.

16
Phases of the Moon

• We have all noticed that the Moon looks
  different from night to night. Sometimes it is in
  a different position in the sky or has a
  different shape or phase.
