What is the greenhouse effect BBC Bitesize?

What is the greenhouse effect BBC Bitesize?

The greenhouse effect is the name given to the natural process that causes the Earth to be warmer than it would be in the absence of an atmosphere. The surface of the Earth is heated by the Sun. Greenhouse gases in the atmosphere trap this heat, keeping the planet warm.

What is the greenhouse effect for kids?

The Short Answer: The greenhouse effect is a process that occurs when gases in Earth’s atmosphere trap the Sun’s heat. This process makes Earth much warmer than it would be without an atmosphere. The greenhouse effect is one of the things that makes Earth a comfortable place to live.

What are the 4 stages of the greenhouse effect?

AP high school/introductory university

  • sunlight in through atmosphere.
  • sunlight hits surface.
  • some sunlight reflected.
  • some sunlight absorbed as heat.
  • some of the surface heat releases infrared radiation into the air.
  • CO2 and other greenhouse gases in the air resonate with the rising IR.

What is Climate Change BBC Bitesize ks1?

Introduction. Climate change refers to the shift in the Earth’s usual weather conditions over many years. Climate change is the result of these actions and it’s already putting humans, wildlife and the planet at risk.

What is the greenhouse effect explained?

The greenhouse effect is the way in which heat is trapped close to Earth’s surface by “greenhouse gases.” These heat-trapping gases can be thought of as a blanket wrapped around Earth, keeping the planet toastier than it would be without them. Remove carbon dioxide, and the terrestrial greenhouse effect would collapse.

What is greenhouse effect GCSE?

The greenhouse effect ensures the mean global temperature is around 15oC and without greenhouse gases the surface of the Earth would swing between extreme heat and extreme cold. The enhanced greenhouse effect, due an increase in greenhouse gas concentrations, most scientists believe, is leading to global warming.

What is the greenhouse effect simple?

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 some is absorbed and re-radiated by greenhouse gases. The absorbed energy warms the atmosphere and the surface of the Earth.

What is greenhouse effect ks3?

Greenhouse effect Some thermal energy from the Earth’s surface escapes into space. However some gases in the atmosphere, called greenhouse gases , trap escaping thermal energy. This causes some of the thermal energy to pass back to the surface. This is called the greenhouse effect , and it keeps our planet warm.

How are greenhouse gases produced GCSE?

Methane, a stronger greenhouse gas than carbon dioxide, but much less abundant in the atmosphere. It is produced both through natural sources and human activities, including the decomposition of waste and agriculture, especially rice farming and animal farming.

What is Climate Change BBC Bitesize?

Climate change refers to changes in the Earth’s average temperature. These changes occur naturally over time, but most scientists think that human behaviour is increasing the amount of greenhouse gases in the atmosphere, which is causing more rapid changes to the climate.

What is a climate BBC Bitesize?

Climate means the average weather conditions in a particular location based on the average weather experienced there over 30 years or more. The weather takes into account the temperature , precipitation , humidity and atmospheric pressure of the part of atmosphere (air) closest to the surface of the earth.
