SCCA ESB. Unit 2 QUIZ ...Am I Ready?

The sun's radiation IONIZES atoms & molecules in our atmosphere. Which 2 layers have the most ionization occurring?

• Exosphere

  & Thermosphere

• Thermosphere & Mesosphere

• Thermosphere & Stratosphere

• Stratosphere & Ionisphere

A protective layer of OZONE forms by ionization in which layer of our atmosphere?

• Exosphere

• Thermosphere

• Mesosphere

• Stratosphere

Answer explanation

Ozone can be good or bad! We need this layer to help shield us from the Sun's harmful radiation.

Which has HIGHER Albedo?

• Asphalt

• Plants

How does a HIGHER Albedo help insulate a building or protect Earth's surface?

• Higher Albedo surfaces REFLECT heat & light more

• Higher Albedo surfaces ABSORB heat & light more

• Higher Albedo has no impact on the surface and its heat

WET sand or WET air holds heat better than dry (higher heat capacity). Knowing this, how can plants contribute to cooling the air around them?

• Plants absorb water vapor from the air, dry it and make it hotter

• Plants release water vapor back into the air, which absorbs the heat and cools the air

• The color of plants absorbs heat & light. That is the only way it impacts Earth's heat

• Plants have no effect on the heat in our atmosphere

Thermal energy also moves around our planet by water. 3 of the 4 statements are true. Which statement is INCORRECT about how i moves in the oceans?

• At the Equator, thermal energy is mostly ABSORBED by the oceans

• At the Poles, thermal energy is mostly RADIATED from the oceans back to the atmosphere

• Surface currents are most responsible for moving energy FROM the equator to the poles

• Deep ocean currents are most responsible for moving energy FROM the equator to the poles

Answer explanation

GYRES (which are Surface Currents) are responsible for MOST of the thermal energy being moved from Equator to Poles!

How do GYRES typically move water in our oceans?

• From the Pacific to the Atlantic Ocean

• Move warm waters from the Equator to Poles

• Move cold waters from the Poles to Equator

• Cold to Warm - from the bottom of the ocean to the top

Ocean Currents have an effect on weather & air temperature on the coast. Which is NOT a way they affect the weather & temperature?

• Warm Ocean Waters directly fuel hurricanes

• Cold Water Upwellings dry the air and decrease rainfall on the coast

• Cold Water Upwellings add moisture and increase rainfall on the coast

• Surface waters called GYRES move warm water from the equator to the poles

Deep Ocean Currents (the Thermohaline Conveyor Belt) moves COLD water in this way....

• On the bottom of the ocean..from the Atlantic to the Pacific

• On the bottom of the ocean..from the Pacific to the Atlantic

• On the top of the ocean..from the Pacific to the Atlantic

• On the top of the ocean..from the Atlantic to the Pacific

Answer explanation

WHY from the Atlantic to the Pacific? the Atlantic ocean is known to be saltier than the Pacific. So water moves from saltier to less salty. The cold, salty water SINKS to the bottom due to density...so that is where it is moved.
