The climate system is powered by radiation from the sun, of which approximately 49% is absorbed by the Earth’s surface, and 20% is absorbed by the atmosphere (Kiehl & Trenberth 1997).
What causes the Earth’s major climate bands?
Sun angle plays a major role in creating Earth’s climate zones. … Prevailing winds and ocean currents then transport this solar heat energy throughout the globe. Factors such as elevation and proximity to the coast help to explain climate variations within a climate zone.
What is responsible for Earth’s climate?
Geological records show that there have been a number of large variations in the Earth’s climate. These have been caused by many natural factors, including changes in the sun, emissions from volcanoes, variations in Earth’s orbit and levels of carbon dioxide (CO2).
What are the 3 factors that affect Earth’s climate?
Introduction: Climate is determined by the temperature and precipitation characteristics of a region over time. The temperature characteristics of a region are influenced by natural factors such as latitude, elevation, and the presence of ocean currents.
What is climate ks2?
Climate is the average measurements of temperature, wind, humidity, snow, and rain in a place over the course of years. Climate is like the weather, but over a long time.
What happens in the Americas during El Niño?
During an El Niño event, the surface waters in the central and eastern Pacific Ocean become significantly warmer than usual. … It also reduces the upwelling of cooler, nutrient-rich waters from the deep—shutting down or reversing ocean currents along the equator and along the west coast of South and Central America.
What caused climate change?
The evidence is clear: the main cause of climate change is burning fossil fuels such as oil, gas, and coal. When burnt, fossil fuels release carbon dioxide into the air, causing the planet to heat up.
What creates a climate system?
Earth’s climate arises from the interaction of five major climate system components: the atmosphere (air), the hydrosphere (water), the cryosphere (ice and permafrost), the lithosphere (earth’s upper rocky layer) and the biosphere (living things).
What are the five major causes of climate?
The National found out the five main culprits for this increase in greenhouse gases.
- Fossil fuels. Expand Autoplay. …
- Deforestation. …
- Increasing livestock farming. …
- Fertilisers containing nitrogen. …
- Fluorinated gases.
Which factor has the most influence on Earth’s climate?
On the surface, the greatest factor affecting Earth is sunlight. Sun provides energy for living organisms, and it drives our planet’s weather and climate by creating temperature gradients in the atmosphere and oceans.
