Answer:

1.

2.Mercury thermometer

Mercury thermometerMercury thermometer shows a faster rise in temperature. It works on the basis that mercury being an element which expands more as the heat increases can detect the change more quickly.

3.Greenhouse gases are trapping more heat in the Earth's atmosphere, which is causing average temperatures to rise all over the world.

4.How does the wall of the aquarium relate to greenhouse gases? The wall of the aquarium prevents heat from flowing out of the aquarium. In the same manner, the greenhouse gases absorb heat and keep it from flowing out of the atmosphere.

5.The greenhouse effect is a natural process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases. ... The absorbed energy warms the atmosphere and the surface of the Earth.

6.Earth's greenhouse gases trap heat in the atmosphere and warm the planet. The main gases responsible for the greenhouse effect include carbon dioxide, methane, nitrous oxide, and water vapor (which all occur naturally), and fluorinated gases (which are synthetic).

7.A greenhouse gas (GHG) is any gas in the atmosphere that absorbs and emits radiation in the thermal infrared range. These are the fundamental cause of the greenhouse effect, which results in increased temperatures on Earth. ... Less heat radiates into space, and Earth is warmer.
