4. Origin and Structure of the Earth- Planet Earth

5. PRE-ASSESSMENT

6. Multiple Choice: Choose the letter of the best answer. 1. Why is Earth called “the living planet?” A. It sustains life. C. It has water at the surface B. It has atmosphere D. All of the above   2. Which among the set of planets are called terrestrial? A. Jupiter, Neptune, Uranus B. Mercury, Venus, Mars, Earth C. Earth, Venus, Mars, Jupiter D. Jupiter, Saturn, Uranus, Neptune 3. What makes the planet Earth habitable compared to other planets? A. It has soil. C. It has people. B. It has trees and water. D. It has solid rocks.

7. 4. What makes planet Earth habitable? A. It has comfortable distance from the sun. B. It has atmosphere that protects from radiation. C. The atmosphere holds carbon dioxide and other gases. D. All of the above   5. Why is Earth called a terrestrial planet? A. It has life B. It is closest to the sun   C. It is farther from the sun D. It is placed at almost the middle planets   6. Which of the following best describes the surface of the planet Earth? A. a thick layer of hydrogen gas B. cloudy and hot with lots of volcano C. cold, rocky, and covered with red dust D. mostly water surface with some areas of land

8. 7. Earth is said to be a unique planet. Which answer verifies the statement? A. It supports life. B. It is mostly covered in water. C. Its atmosphere is mostly nitrogen and oxygen. D. All of the above   8. Which is supported and sustained by planet? A. life C. a rocky core B. a moon D. an atmosphere   9. How many percent of water comprises the Earth? A. 15% C. 50% B. 30% D. 70%

9. 10. Which factors are needed for organisms to live on Earth? A. temperature and nutrient B. atmosphere and energy C. only A D. both A and B

11. What do you think are the characteristics of the planet Earth that make it different from all the other planets?

12. PLANET EARTH:THE LIVING PLANET it has the right distance from the sun it is protected from harmful solar radiation by its magnetic field it is kept warm by an insulating atmosphere it has the right amount of ingredients for life, including water and carbon .

13. DISTANCE Time = Distance/speed so Time = 150,000,000 km/ 28,000 = 5322 hours or  223 days .

14. MAGNETIC FIELD

15. INSULATING ATMOSPHERE

16. RIGHT AMOUNT OF INGREDIENTS FOR LIFE WATER : About 70 percent of the Earth's surface is water-covered because of that Earth is sometimes called “ blue planet .” CARBON DIOXIDE : Carbon dioxide atmosphere warms the planet

17. Earth, Venus, and Mars similarities They all are terrestrial planets , made of solid rocks and silicates (a salt in which the anion contains both silicon and oxygen); They all have an atmosphere ; They all almost have the same time to rotate on their axes; Earth and Mars both have water ; They all have carbon dioxide ; and All have landforms

18. Earth, Venus, and Mars have differences Venus has no water; Venus and Mars don’t have oxygen; and Earth has life forms.
