What are the chemicals that cause ozone depletion?

Ozone depleting substances are chemicals that destroy the earth’s protective ozone layer….They include:

  • chlorofluorocarbons (CFCs)
  • halon.
  • carbon tetrachloride (CCl4)
  • methyl chloroform (CH3CCl3)
  • hydrobromofluorocarbons (HBFCs)
  • hydrochlorofluorocarbons (HCFCs)
  • methyl bromide (CH3Br)
  • bromochloromethane (CH2BrCl)

Which chemical is mainly linked to drop in ozone in the atmosphere?

Chlorofluorocarbons (CFCs)

Is the inside of the Earth mostly solid or liquid?

The Earth’s interior is composed of four layers, three solid and one liquid—not magma but molten metal, nearly as hot as the surface of the sun. The deepest layer is a solid iron ball, about 1,500 miles (2,400 kilometers) in diameter. Although this inner core is white hot, the pressure is so high the iron cannot melt.

What four things increase the deeper you go into Earth?

4 Density increases the deeper in Earth you go. This is because as you go deeper into the earth, pressure, and temperature increase. The inner core is the most dense layer because of its composition.

How thick is the upper mantle?

about 640 km

What are 5 facts about the mantle?

Planet Earth

  • The Mantle is the second layer of the Earth.
  • The mantle is divided into two sections.
  • The average temperature of the mantle is 3000° Celsius.
  • The mantle is composed of silicates of iron and magnesium, sulphides and oxides of silicon and magnesium.
  • The mantle is about 2900 km thick.

What is the most abundant rock in the mantle?

Silicates

What temperature is the mantle?

The temperature of the mantle varies greatly, from 1000° Celsius (1832° Fahrenheit) near its boundary with the crust, to 3700° Celsius (6692° Fahrenheit) near its boundary with the core. In the mantle, heat and pressure generally increase with depth.

Is Earth’s mantle hotter than the crust?

New data suggests that the upper parts of Earth’s mantle are around 60°C (108°F) hotter than previously expected. Previous estimates have put temperatures ranging from anywhere between 500 to 900°C (932 to 1,652°F) near the crust, to 4,000°C (7,230°F) closer to Earth’s core.

What is the depth of the mantle?

2,890 km

Why is the mantle so hot?

There are three main sources of heat in the deep earth: (1) heat from when the planet formed and accreted, which has not yet been lost; (2) frictional heating, caused by denser core material sinking to the center of the planet; and (3) heat from the decay of radioactive elements.
