Ms. Chelsea

 Take good notes in class. Put titles on everything  Read through your notes and book when you are going through the Study Guide  If you don’t have a section, ask a friend for notes  Have a family member or friend ask you questions about the information  PAY ATTENTION IN CLASS! ASK QUESTIONS WHEN YOU DON’T UNDERSTAND!

 Talk to someone next to you…

 We need the sun to survive Solar energy: the energy from the sun  The Earth’s rotation, revolution, tilt, and latitude affect the amount of solar energy different parts of the Earth receive

 Axis: the rod or pole running through it from the North to the South Pole  Rotation: one complete spin of the Earth on its axis

 One complete rotation takes 24 hours  Causes day and night  The sun appears to move in the sky, but doesn’t

 At the same time the Earth is spinning on its axis, it also follows a path around the sun Orbit: the Earth’s path around the sun  On this path, sometimes the Earth is closer to the sun and sometimes it is farther away

 Revolution: one trip around the sun 365 ½ days (a year)

 The Earth is not straight up and down in the sky  It is on a tilt (angle) 23.5 degrees  Some locations are always tilting away from sun and some are always tilting toward it  QA QA

 A location’s latitude also affects its amount of solar energy Latitude: distance North or South of the Earth’s Equator  Let’s look at a map

 Season: period during the year that have a particular type of weather Winter, Spring, Summer, Fall  Seasons are characterized by their temperature and length of day (and sometimes amount of rainfall)

 Northern and Southern hemispheres experience opposite seasons.

 Summer: Earth tilted towards the Sun Direct solar energy Warmer temperatures Longer periods of daylight  Winter: Earth tilted away from the Sun Colder temperatures Shorter periods of daylight

 In Spring and Fall, the poles don’t tilt toward or away from the Sun  Spring: part of the Earth begins to tilt toward the Sun  Fall: part of the Earth begins to tilt away from the Sun

Flap 1: Rotation  Define rotation  Label the time it takes for one Earth rotation  Draw a picture/diagram to show Earth’s rotation Flap2: Revolution  Define revolution  Label the time it takes for one Earth revolution  Draw a picture/diagram to show Earth’s revolution Inside Flap: Seasons  Explain the cause of Earth’s Seasons (Tilt?)  Draw 4 pictures to show the climate/characteristics of each season  Fill in the blank: Summer in North America = ________ in Australia Spring in North America = _____ in Australia Autumn in North America = _____ in Australia Winter in North America = _____ in Australia
