SGM Climate Change Pre-Test- 8.11 A

Analyzing the phenomena in the picture above, please determine how greenhouse gasses contribute to climate change? (Level 3)

• They reflect sunlight back into space, cooling the Earth.

• They trap heat in the Earth's atmosphere, leading to rising temperatures.

• They promote cloud formation, which decreases rainfall.

• They absorb water vapor, increasing humidity levels.

In what way do changes in ocean currents affect global climate patterns?

• Ocean currents are unaffected by climate change and remain constant.

• Changes in ocean currents can redistribute heat around the planet, leading to changes in weather patterns and potential increases in extreme weather events.

• Ocean currents only impact the climate of coastal regions and do not influence inland areas.

• Changes in ocean currents only occur due to human activity and have no natural causes.

What were some of the short-term climate effects of the ash cloud produced by the 1991 Mt. Pinatubo eruption?

• The ash cloud blocked sunlight, leading to a temporary decrease in global temperatures.

• The eruption increased global humidity, resulting in more frequent storms.

• The ash cloud did not have a noticeable effect on the climate or local weather.

• The ash increased agricultural production in the years following the eruption.

Evaluate the potential impact of a large meteor impact on Earth's climate based on past scientific evidence. (Level 3)

• Large meteor impacts can cause the Earth's atmosphere to become warmer due to friction generated from the collision.

• Large meteor impacts can lead to global cooling by sending dust and debris into the atmosphere, blocking sunlight and disrupting photosynthesis, which can lead to mass extinctions.

• Large meteor impacts have little effect on the Earth's climate because their effects are quickly dissipated.

• Large meteor impacts increase global warming by adding kinetic energy into the atmosphere.

A monsoon is the seasonal increase in summer precipitation that occurs

during the months of June to September. Recent data shows more frequent and severe

monsoon, resulting in devastating floods and droughts in the monsoonal regions.

What could be the most probable cause for this phenomenon?

• A) A natural shift in Earth's tilt

• B) Increased deforestation

• C) Rising global temperatures due to climate change

• D) Decreased solar activity

In 2010, the world released a lot of carbon dioxide (CO2) into the air, and scientists say if we keep adding greenhouse gasses, it will be hard to keep the Earth's temperature from rising too much. What could happen if we keep putting a lot of greenhouse gasses into the air?

• Some places will get less rain.

• Summer days will be cooler.

• There will be stronger storms and more floods.

• Some areas will have colder winters.

Major surface currents of the ocean are shown in the diagram. Ocean currents affect weather patterns by —

• regulating when tides occur in coastal areas

• trapping heat at the equator to regulate the global climate

• distributing heat from the uneven absorption of solar energy

• increasing the rate of evaporation to transport water to areas experiencing droughts

Hurricane and storm activity tend to be much higher during the months of September and October because:

• ocean temperatures are at their warmest, providing more energy for storms to form and intensify.

• the days are shorter and there is less sunlight.

• there is less moisture in the air during these months.

• wind speeds are generally lower in September and October.

If humans continue their destructive actions toward planet earth, what is likely to happen to hurricane activity for future generations?

• Hurricane activity will decrease and become less intense.

• Hurricane activity will remain the same.

• Hurricane activity may become more intense and frequent.

• There will be no hurricanes in the future.

How does the ocean taking in greenhouse gasses affect Earth’s climate?

• It stops greenhouse gasses from reaching the air, so they don’t cause global warming.

• It slows down global warming for a while, but once the ocean can’t take in more, the gasses stay in the air and speed up climate change.

• It cools the Earth by getting rid of the heat trapped by greenhouse gasses.

• It doesn’t affect the climate at all.
