The Atmosphere

Question 1

Troposphere?

Answer 1

Troposphere:
*0 to 12 km, contain 75% of gasses.
*here living and weather occurs
*height 👆,Temperature 👇
➕Tropopause: located at top, the layer separates it from stratosphere. 
☑️jet stream found here, Strong winds.

Question 2

Stratosphere?

Answer 2

🔸12 to 50 km,
🔸constant temp -60•c
🔸contain Ozone layer.
🔸absorb UV rays cause ⬆️ temp

Question 3

MESOSPHERE:

Answer 3

🔹50 to 80 km, temp ⬇️ -100•c
🔹coldest region
🔹layer that protect earth from meteroids by burning it down

Question 4

Thermosphere:

Answer 4

▫️80km to up.
▫️it means heat sphere.
▫️temperature ⬆️ coz UV radiation, it reaches 2000•c
➕IONOSPHERE: Lower part, 80 to 550km,
🔻Gas particle absorb UV & X-Ray radiation
🔻helps in radio communi coz radio waves bounced off the ions back to earth.
➕EXOSPHERE: upper part of thermo
🔺550km ↗️1000 km
🔺thin air
🔺area where satellites orbit earth.

Question 5

EXOSPHERE?

Answer 5

▪️upper part of thermospehere

Question 6

Atmosphere?

Answer 6

• Divided into layers
• Gravity pushes layers of air down on earth’s surface(air pressure)
• 99% of atmosp’s mass in below 32km
