Discuss the technique used for studying population density and explain the strength and weakness of each technique in its application.

Answers

Answer 1

A population's size refers to the number of individuals (N) it comprises. Population density is the number of individuals within a given area or volume. Scientists usually study populations by sampling, which involves counting individuals within a certain area or volume that is part of the population's habitat.

1. It contains large amounts of frozen water
2. The temperature of its atmosphere is increased by high levels of carbon dioxide
3. It doesn't have enough gravity to have an atmosphere
4. Astronomers believe there is a good chance it contains liquid water

Answers

Final answer:

The characteristics of the respective bodies are: Earth's Moon doesn't have enough gravity to hold onto an atmosphere, Venus has an atmosphere with high levels of carbon dioxide, Europa could contain liquid water according to astronomers, and Mars contains large amounts of frozen water.

Explanation:

Matching each celestial body with its characteristic is:

Earth's moon (A) aligns with 'It doesn't have enough gravity to have an atmosphere' (3). The Earth's moon doesn't have an atmosphere because its gravity is not strong enough to hold onto one.Venus (B) matches with 'The temperature of its atmosphere is increased by high levels of carbon dioxide' (2). Venus' thick atmosphere is made up primarily of carbon dioxide, trapping heat and creating a greenhouse effect.Europa (C) is paired best with 'Astronomers believe there is a good chance it contains liquid water' (4). Europa, a moon of Jupiter, is believed to possibly have an ocean of water underneath its icy surface.Mars (D) is correctly coupled with 'It contains large amounts of frozen water' (1). Scientists have found evidence of vast amounts of ice on Mars, especially at its poles.

Currently, about 10% of Earth is covered with ice year-round. If this ice melts, what could happen to Earth's temperature?

Answers

If the ice melts, the temperature could increase.

Hope this answer helps, If you have any other questions just feel free to ask :)

The temperature of the earth will increase if the 10% of the earth ice melt.

Let understand that Ice formation especially in the Antarctica and other part plays a great role in the maintaining of the earth temperature.

Basically, the excess radiation of the Sun on the Earth surface are sent back into the Space through the Ice.

Thus, if the ice melts, then, the earth will keep absorbing all the sun radiation and heat, leading to increase in temperature.

Therefore, in conclusion, the temperature of the earth will increase if the 10% of the earth ice melt.
