Question

question 3 (multiple choice worth 3 points)
which of these earth systems is most responsible for the increases in global warming?

• biosphere
• geosphere
• cryosphere
• exosphere

question 4 (multiple choice worth 3 points)
which of these is an example of how the ocean influences climate?

• the gulf stream current carries warm ocean water toward europe.
• the gulf stream carries heat away from regions in southern florida.
• during night time, oceans carry heat away from locations in coastal florida.
• during day time, oceans carry heat towards locations in coastal florida.

Explanation:

Question 3

Global warming's increase is linked to the biosphere (human activities like deforestation, fossil fuel use) releasing greenhouse gases. Geosphere (solid Earth) has minor impact, cryosphere (ice) is affected by warming, exosphere is outer space. So biosphere is most responsible.

The Gulf Stream carries warm water to Europe, influencing its climate (making it milder). The other options have errors: Gulf Stream warms Florida, oceans at night release heat (don't carry away), during day absorb heat.

Answer:

A. Biosphere
