Answer:
The solution slowly descends into the cave and deposits the dissolved calcium carbonate, sometimes including impurities of iron and other minerals. On reaching the cave, the water droplets fall to the floor, leaving behind a tiny deposit of calcite crystal.

Answer:
Negative
Explanation:
Aerosol -
It is the suspension of the solid or liquid particles in the air , is known as the aerosol .
The effect of aerosol is , that it reduces the amount of the solar radiations incident on the surface of the Earth , and due to this capacity to reflect the solar radiations , it has a negative impact on the Earth .
As we known solar energy are of huge importance for the human beings .
Hence , the answer is negative .
Answer:
d). It is easier to make a large reflecting telescope than a large refracting telescope.
f). A reflector can collect more light than a refractor.
Explanation:
A telescope is a device that is used to observe distant objects by the use of lenses and mirrors. It is also used to observe different distant objects by their reflection, absorption, emission or the reflection of the electromagnetic radiations.
Most of the professional telescopes are reflectors because :
1. The reflected telescope is able to receive more of the light when it reflects all the light falling on surface. And it is easier for making a large telescope rather then making large lenses for the refracting telescope. So it is easier to make large reflecting telescope than a large refracting telescope.
2. A reflected telescope receives all the wavelength of the light and it reflects all the light falling on the surfaces where it is refracted telescope that contains lenses cannot absorbs all the light and causes the chromatic aberration.

Answer:
- shows isobars
- was probably used by meteorologists
Explanation:
The map that is show was a map that was probably made and used by meteorologists. It is a map that that shows isobars, thus it is a map that represents the air pressures across the US and Canada. We can see the air pressure zones, some of which high, some of which low. These maps are often used when the weather information is concluded about certain areas, as the air pressure is directly connected with the temperature, and the movement of the air masses.
