1 Earth in Space

2 The Solar System

3  Major Planets:  Inner planets – Mercury, Venus, Earth, Mars  Relatively small and solid.  Outer planets – Jupiter, Saturn, Uranus, Neptune  Large and composed mostly or entirely of gas.  Orbit is the path that the planets travel around the sun.  They follow nearly circular, elliptical paths.  The planets complete an orbit at different speeds.  88 days for Mercury, 165 years for Neptune

4 Earth’s Movement  Revolution – one circuit around the sun  Rotation – the Earth spinning on its axis  Axis – an imaginary line that passes through the Earth from Pole to Pole  Why do we not feel the Earth Move?  Size  Atmosphere – layer of oxygen and gases that move with it

5 What causes the seasons?

6 Sun and Seasons  The tilt of the Earth and its revolution around the sun causes the seasons to change throughout the year.  Page 37  The summer solstice – the day with the most hours of sunlight in the Northern hemisphere, and the beginning of summer  The sun’s rays directly hit the Tropic of Cancer  The winter solstice – the day with the fewest hours of sunlight, and the beginning of winter  The sun’s rays directly hit the Tropic of Capricorn  Equinox – days when there are equal hours of day and night  The beginnings of spring and autumn, and the sun shines directly on the Equator

7 Effects of Latitude  The further away from the Equator and the Tropics, the colder the temperatures.  The areas around the Arctic and Antarctic circles sometimes go days without receiving any sunlight,  They also go days without any night.
