  2. Table of Contents

  3. EQ 8 p.8 • Q: What is the atmosphere and why is it important? • Earth’s atmosphere is the layer of gases that surrounds the planet. • It makes conditions on Earth suitable for living things.

  4. EQ 9 p.9 • Q: What is the sequence of Earth’s atmospheric layers? • Troposphere • Stratosphere • Mesosphere • Thermosphere • Exosphere • THINK: EaT MoST

  5. EQ 9 p.9 Q: Now go back to EQ 9 & explain the prefixes of Earth’s atmospheric layers. 1. Troposphere: tropo = changing 2. Stratosphere: strato = layer 3. Mesosphere: meso = middle 4. Thermosphere: thermo = heat 5. Exosphere: exo = outer

  6. EQ 10 p.10 • Q: How are the atmospheric layers alike/different in regards to gases? • Nitrogen (78%) & Oxygen (21%) are the two most common gases; found in all the layers. • Ozone is a form of oxygen (o-o-o) found in the ozone layer in the stratosphere. • Water vapor & Carbon dioxide are important gases for weather conditions; found in the troposphere. • Trace gases play an insignificant role

  7. EQ 11 p.11 Q: Explain the relationship between air pressure and the atmospheric layers. Air pressure is a force exerted by the gases in the atmosphere. It is greatest in the troposphere & least in the exosphere. Air pressure DECREASES with altitude because Earth’s gravitational pull decreases.

  8. EQ 12 p.12 Q: Explain the relationship between temperature and the atmospheric layers. Troposphere: As altitude increases temperature decreases. Stratosphere: Cold, but gets warmer near ozone layer. Mesosphere: Coldest layer Thermosphere: Hottest layer Exosphere: Cold regions of outer space

  9. EQ 13 p.13 • Q: What is solar energy? • The sun (solar energy) is the driving energy source for heating the Earth. • Circulation in the Earth’s atmosphere comes from the sun.

  10. EQ 14 p.14 • Q: What happens to the sun’s energy coming through the atmosphere? • It is absorbed or reflected by the gases & clouds in the atmosphere.

  11. EQ 15 p.15 • Q: What is the difference in how land & water absorb solar energy? • The LAND absorbs solar energy quicker and it cools off quicker than water. • The WATER absorbs solar energy slower and it cools off slower than land. • It is the WATER that helps regulate the temperature range of Earth’s atmosphere.

  12. EQ 16 p.16 • Q: What is the ‘greenhouse effect”? • When gases in the atmosphere trap heat that is reflected from Earth’s surface, this is called the ‘greenhouse effect’.
