1 Hubble Telescope

2  Space and Universe  Universe is made up of all existing things, including space and earth  Space is filled with objects called stars. Most are found in galaxies.  Milky Way

3 Milky Way

4  Planets- major bodies that orbit a star  Four inner planets: Mercury, Venus, Earth, Mars  Terrestrial- which means solid, rocky surfaces  Five outer planets: Jupiter, Saturn, Uranus, Neptune, Pluto  Mainly gaseous, with the exception of Pluto which has a rocky core

5  Sun, Earth, and Moon  Diameter of sun = 865,000 miles, more than 100 times greater than the earth  Earth’s diameter=8,000 miles  Earth is the third planet from the sun  Fifth largest planet  Earth’s orbit is elliptical  Moon is 240,000 miles away  ¼ the size of earth  Influences the earth’s ocean tides

6  Solar energy- energy that comes from the sun, which all of the earth’s energy comes from  Affects weather, plants, animals, and human  Rotation  One complete spin of earth on its axis  Takes 24 hours  Rotates in a west to east direction  See the effects as the sun rises in the east and sets in the west  Allows the entire planet to receive the warming effect of daylight and the cooling effect of darkness

7  Revolution  Earth also revolves around the sun  Elliptical orbit every 365 ¼ days, 1 year  Every 4 th year, have an extra day in February

8  Tilt  Tilted 23 ½ degrees from perpendicular  Affects the amount of solar energy that different places receive during the year

9  Solar energy and Latitude  Different places on the earth receive different amounts of solar energy  Near the equator receives a lot yearly  Tropics- warm low latitude areas near the equator  Polar regions- areas of high latitude and colder regions near the North and South Poles receive less solar energy

10  The Seasons  Times with greater or lesser heat  Winter, spring, summer, fall  Summer  Solar energy is stronger, warmer and longer days  Winter  Solar energy is weaker, colder and shorter days  Spring/Fall  Solar energy is more evenly distributed  Daylight and darkness are more equal

11

12  Tilt of the earth causes Northern and Southern Hemispheres to have opposite seasons  Solstice  The time that the Earth’s poles point at their greatest angle toward or away from the Sun  Occur each year around Dec. 21, and June 21  Winter Solstice (Dec 21)  Northern Hemisphere- shortest day, first day of winter  Sun most direct rays strike the Tropic of Capricorn  Antarctic Circle- receives 24 hours of daylight  Arctic Circle- recieves 24 hrs of darkness

13

14  4 major parts of Earth’s System that are all linked together  Atmosphere  Lithosphere  Hydrosphere  biosphere

15  Shell of gases that surround the Earth  Extends from the earths surface to space  Gravity holds the atmosphere in place  78%nitrogen, 21%oxygen, and rest is made up of CO2, and other gases  Protects the Earth from the Sun’s harmful radiation OT92wuD8

16  Solid Crust of the planet  All the land on the earth  Forms, continents, islands and ocean floors

17  All the Earth’s water  Liquid, solid, and gaseous forms  Covers about 70% of the earth’s surface  Part of the Earth that includes all life forms  Includes plants and animals  Extends deep in the ocean to the atmosphere  Overlaps the other 3
