Humans have taken some steps to reverse or control the negative effects of human-led climate change. which of the following events shows one step toward reducing the impact of climate change?
a. fossil fuel consumption in the united states has risen steadily since 1900.
b. the mount kenya glacier in africa has lost 92 percent of its mass over one century.
c. use of renewable energy, like wind power, will increase 4% globally over the next few years.
d. to meet higher food demands, land for raising livestock has reached 26% of earth’s total land surface.

The correct answer is (c) Use of renewable energy, like wind power, will be increasing and will reach upto 4% globally in the coming few years.

Humans have shown efforts to reduce the effect of the human interventions  that led to climate change by increasing the use of renewable energy like wind energy, and the use of wind energy that will increase 4% globally over the next few years. The use of wind energy will help in reducing the negative effect of human led climate change.

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
