What would happen to the climate if earth took more energy than released?
Gnoma [55]

<u>ANSWER:</u>

If Earth took more energy than it released, the "climate would be warmer". This would result in more problems such as the rise in temperature and global warming due to the "greenhouse effect".

<u>EXPLANATION:</u>

  • The Earth absorbs solar energy in the form of infrared rays emitted from the sun.
  • These infrared lights are filled with harmful radiations which are bounced off from the Earth's atmosphere with the help of the ozone layer.
  • If the Ozone layers deplete, the heat and radiant from these rays have nowhere to leave and is taken by the Earth itself.
  • This results in the rise of temperature and more warmer climates that could have devastating effects on Earth.

borishaifa [10]

Answer:

B.) Take samples from the same location each time.

Explanation:

The original answer choices to this question are the following:

  • Provide details about the creatures in the "other" category.
  • Take samples from the same location each time.
  • Collect samples from nearby lakes for comparison.
  • Use a more sophisticated net to collect smaller creatures.

Phoebe should take samples from the same location, rather than four different locations. This will overall give her more accurate and reliable results. Some areas of the lake will have more or less wildlife depending on what predators and prey live. She must have a control variable in this survey, otherwise her data will not be correct.

Hope this helps :)
