Consider the global 'Greenhouse Effect", where thermal energy from the sun is naturally trapped by 'greenhouse gases' present within the Earth's atmosphere. A majority of heat generated from this process is then absorbed by the world's oceans, where it is sequestered and stored. What are some of the predictable consequences recently observed over the past 40-50 years with the observed rise in Global Mean Temperature, correlate with an increase in greenhouse gas emissions from burning of fossil fuels across that same period?
a. retreat of winter and summer sea ice, decreasing the amount of solar energy directly absorbed into the oceans
b. warming of deep ocean water and increased evaporation at the surface
c. warming of oceanic surface temperatures, driving the formation of more powerful hurricanes & rainstorms
d. thermal expansion of oceanic water, leading to mean global sea level rise
e. melting of Himalayan glaciers and collapse of Antarctic ice shelves into the sea

Answers

Answer: it would be C e is correct however but that’s already happened. So that wouldn’t be much of a prediction. Hope this helped :)

Explanation:

Thermal expansion of oceanic water leads to a main global sea level rise. So the correct option is D.

What is the greenhouse effect?

Because it absorbs heat in the form of infrared light from the Sun, a greenhouse gas circulates that heat throughout the atmosphere before losing it to space. Although it has a considerably smaller impact on global temperatures, greenhouse gases also speed up the pace at which the environment can collect short-wave radiation emitted by the Sun.

More heat from the Sun is being trapped in our atmosphere thanks to the accumulation of CO2 that is emitted after the combustion of fossil fuels. Human-made acts are referred to as anthropogenic actions, and the emission of CO2 is one such anthropogenic activity that adds to the current heightened greenhouse effect.

A greenhouse gas's contribution to the greenhouse effect is determined by how much energy it absorbs, how much it reflects back, and how much of it is present in the atmosphere.

Therefore the correct option is D.

Tell the story of the predator/prey loop.
If the owl population goes up, then ...


Answers

Answer:

Below : )

Explanation:

Well, in most cases if the predator population rises most likely the prey population decreases this is because there is a big population of the predator which allows more of them to eat the prey so the prey decreases. Now when the prey decreases this again affects the predators because now the predators are limited to food so that causes many of them to decrease.

In this scenario, if the owl is the predator, as the population rises, its prey will decrease.

If the owl is the prey, the predators would most likely increase.
