1 Earths Structure and Motions By: Abigail Ruiz And Vanessa Umaña

2 Formation of Solar System Cloud of spinning gas and dust. 4.6 billion years ago Planets (Earth) formed from compression of the gasses.

3 Earths Layers Crust. Mantle. Outer Core. Inner Core.

4 Three Sources of Internal Heat Friction Radiation Meteor Impact

5 The axis is tilted and one hemisphere faces towards the sun and it causes warmer longer days. The other hemisphere barely gets sunlight and has cooler shorter days How Earth causes Seasons

6 How Earth Causes Days rotates on its axis. 24 hours to rotate When one side faces the sun its day. When the other side faces the moon its night.

7 How did the Solar System First start? A. a cloud of spinning gas and dust. B. Meteors and Asteroids. C. Dust particles and magic.

8 How did the solar system first start? A. a cloud of spinning gas and dust. B. Meteors and Asteroids. C. Dust particles and magic.

9 What are Earths layers in order from outer to Inner? A. Outer Core, Crust, Mantle, and Inner Core B. Crust, Outer Core, Inner Core, and Mantle C. Crust, Mantle, Outer Core, and Inner Core.

10 What are Earths layers in order from outer to Inner? A. Outer Core, Crust, Mantle, and Inner Core B. Crust, Outer Core, Inner Core, and Mantle C. Crust, Mantle, Outer Core, and Inner Core.

11 How does Earth cause days? A. Earth has a light switch to turn days and nights off and on. B. When one side faces the sun its day and when the other side faces the moon its night. C. rotates on its axis and it takes 24 hours to rotate. D. Both B and C E. Both A and B

12 How does Earth cause days? A. Earth has a light switch to turn days and nights off and on. B. When one side faces the sun its day and when the other side faces the moon its night. C. rotates on its axis and it takes 24 hours to rotate. D. Both B and C E. Both A and B

13 !!!!!!Answers!!!!!!

14 1. How Does Science explain the Formation of our Solar System? A cloud of spinning gas begins to pull together because of gravity 4.6 billion years ago and created all our planets.

15 2. Describe the Earths Layers Down To Its Core. A. Crust B. Mantle C. Outer Core D. Inner Core

16 3. List Three Sources Of Internals Heat. A. Friction B. Radiation C. Meteor Impact

17 4. Explain how Earths motions cause days, and seasons. Days and nights Earths rotation is the daily change from day to night. From the north pole, earth rotates clockwise. The sun appears to rise in the East and set in the West. Seasons The hemisphere tilted towards the sun receives more sunlight and has warmer and longer days. The hemisphere tilted away from the sun receives indirect sunlight and it has cooler and shorter days.
