A GeoChart is a tool used to visualize data on a map. The size of the circular
7nadin3 [17]

Explanation:

We know that the larger the circle, the more large the diameter of the circle the more the quantity being studied.

We can clearly see that the South eastern coast of Australia has more number of people diagnosed with cancer.

The South western and the Northern part also records a sizable amount of skin cancer cases.

  • In the middle part of the map where the circles are small, the number of people diagnosed  with cancer is very low
  • Other areas without the circle did not record any case of skin cancer.

_____ radiation lies at frequencies just below the frequencies of visible light.
olga2289 [7]
Infrared radiation lies at the frequency just below the frequencies of visible light.

Infrared radiation is termed as an electromagnetic radiation which has longer wavelength more than those which have visible light.
Infrared radiation excites vibrational modes in a molecule through which a change in the dipole moment. Infrared examines transmission and absorption of photons which are in the infrared range. Infrared radiation is used in scientific, military, law enforcement, in industrial, and medical applications.

Why does Ice Float on water? How does this affect life in Earth’s aquatic environments?
Sonbull [250]

This because ice is less dense than water of particular temperature range.  Water reaches its maximum density at 4 degrees. Ice is important especially for aquatic  life in the polar regions. Polar bears give birth and hunt on sea ice and they need it to travel from one region to another. The ice edge in coastal areas is an important feeding ground for the walrus that uses the ice as diving platforms to feed on clams on the sea floor. Ice algae grow at the porous bottom of sea ice and form the base of the unique marine food web connected to sea ice

As a student in an environmental science class, you have been asked to explain the greenhouse effect and the problem we face, in
ser-zykov [4K]

C) The increase in greenhouse gas emissions is like placing an extra log on the fire to produce more heat.

Explanation:

The increase in greenhouse gas emission cannot be likened to placing an extra log on the fire to produce more heat.

In essence, the earth is not receiving more heat than usual from the sun. It is not getting more heated.

  • Greenhouse gases prevents heat from being lost from the earth surface as long wave radiation.
  • This in turn will warm and heat the earth surface.
  • The more the greenhouse gases, the more heat that is trapped within the earth.
  • The greenhouse gases is the cover that prevents heat from being lost.
  • Global warming is what results.
  • An increase in heating might not cause warming of the house if the house is open.
  • So also, if the earth receives more energy from the sun, the temperature might not increase if no greenhouse cover is available.

Other analogies shows heating(global warming) and cover(greenhouse gases) except of C.
