Answer 1

Based on the questions provided, here are the answers following the instructions:

A) 1. Evidence of climate-forced sea level rise:

• submerging of low islands and coastlines

B) 2. Changes in carbon dioxide in the Earth's atmosphere since 1860 (select 2):

• The increases in carbon dioxide are caused by human activity.
• The rate of change in carbon dioxide is exponential.

C) 3. Item topics (the specifics aren’t provided, so let’s assume you match them based on context):

• You'll need to match each item with appropriate scientific study categories, such as climate change, biology, geology, etc., based on course materials.

D) 4. Quality of a greenhouse gas:

• absorbs and re-emits infrared radiation

E) 5. Items that directly contribute to sea level rise:

• expansion and melting of land ice

F) 6. Correct sequence of cause-and-effect relationships due to human activity:

• increased carbon dioxide in the atmosphere; increased water vapor in the atmosphere; increase in severe storms; increased flooding

G) 7. Measures governments could take to decrease the negative effects of climate change (select 2):

• Transition from power plants that burn natural gas to those that do not use fossil fuels.
• Give tax incentives for energy conservation in homes and businesses.

H) 8. [Without specific items, I can’t provide concrete answers. You will need to complete based on course material.]

I) 9. Studying the pH of oceans:

• the health of coral reefs

J) 10. Weaker jet stream causing extreme flooding:

• It would allow storm systems to stall in an area.

K) 11. Earth without the greenhouse effect:

• There would be more ice on Earth's surface.

L) 12. Link between fossil fuel use and flowers blooming earlier:

• A warmer Earth due to fossil fuel emissions has milder winters and earlier springs.

M) 13. Condition expected on Venus due to a runaway greenhouse effect:

• The planet is extremely hot.

N) 14. Gas recently increased in the mesosphere leading to high-altitude clouds:

• methane

O) 15. Fill in the blanks (assuming specific phrases are to be inserted):

• "Climate change causes warming of oceans and ice melting. This results in sea level rise, which affects coastal ecosystems. Severe storms fueled by climate change cause all of the following EXCEPT a reduction in rainfall. Ocean acidity caused by climate change causes all of the following EXCEPT increased fish populations."

P) 16. Fill in the blanks (selecting from provided options based on context):

• "Machines began replacing animals and humans for doing hard labor in the Industrial Revolution. Since then, this transformation has affected the labor market. As a result, carbon emissions have increased since 1960. Some scientists believe that all of the following have occurred as a result EXCEPT a decrease in global temperatures."

Q) 17. [Similar to earlier, without specific terms, I can’t provide answers.]

Please adjust blanks and specific details with the context you have from classroom materials.
