Question

what is the function of the ozone layer? *
5 points
it traps heat in the atmosphere
it prevents damaging amounts of uv radiation from reaching earth\\s surface
it causes acid rain
it regulates global carbon dioxide levels

according to the text, what happens when biodiversity is reduced on a farm? * 5 points
crop yields increase
the need for pesticides increases
soil quality improves
water usage decreases

what is described as a temperature rise that might lead to climatic changes? * 5 points
acid rain
ozone depletion
global warming
biodiversity reduction

Explanation:

1. For the ozone layer question: The ozone layer absorbs most of the Sun's harmful ultraviolet (UV) radiation, protecting life on Earth's surface. Heat trapping is done by greenhouse gases, acid rain is from pollutants like sulfur dioxide, and carbon dioxide regulation is not its function.
2. For the farm biodiversity question: Reduced biodiversity removes natural pest predators, so more pesticides are needed to control pests. Yields typically decrease, soil quality worsens, and water usage does not decrease in this scenario.
3. For the temperature rise question: Global warming is defined as the long-term rise in average global temperatures, which drives climatic changes. Acid rain is acidic precipitation, ozone depletion is loss of ozone layer, and biodiversity reduction is loss of species variety.

Answer:

1. It prevents damaging amounts of UV radiation from reaching Earth's surface
2. The need for pesticides increases
3. Global warming
