Substances called Response area are important because they act as a blanket to keep Response area in our atmosphere. However, human activities can Response area the concentrations of greenhouse gases in the atmosphere so much that they keep too much thermal energy in the atmosphere. This causes global temperatures to Response area, which is a phenomenon called Response area. This phenomenon is one contributing factor to changes in long-term weather patterns known as Response area.

How does each fact impact greenhouse gas concentrations?
(4 points)
increase greenhouse gases decrease greenhouse gases
Dead trees decay.
Living trees hold lots of carbon in their trunks, branches, roots, and leaves.
Dead trees stop performing photosynthesis.
Living trees perform photosynthesis.
The impact of each fact on greenhouse gas concentrations is as follows:
- Dead trees decay: This fact would increase greenhouse gases.
- Living trees hold lots of carbon in their trunks, branches, roots, and leaves: This fact would decrease greenhouse gases.
- Dead trees stop performing photosynthesis: This fact would increase greenhouse gases.
- Living trees perform photosynthesis: This fact would decrease greenhouse gases.
Many aquifers are at risk of running dry. Explain this critical situation to a friend by putting the following facts in the most logical order. Drag each statement into the correct order, going from the first step at the top to the last step at the bottom.(2 points)
Arrange responses in the correct order to answer the question. Select a response, navigate to the desired position and insert response at that position. Responses can be selected and inserted using the space bar, enter key, left mouse button or touchpad. Responses can be moved using the up and down arrow keys or by dragging with a mouse.
When this pumping exceeds the recharge rate, the aquifer can run dry.
Humans pump water out of aquifers for household, industrial, and agricultural use.
Water collects in silt, sand, and gravel located in underground regions called aquifers.
Water from precipitation and snowmelt seeps through the ground.
