What determines the Earth’s temperature?
sunlight Air and water temperatures are primarily determined by the amount of sunlight that is absorbed by the surface of the Earth, and the amount of heat that is re-radiated in the atmosphere by the greenhouse gases.
Which regulate the temperature of the Earth?
Water vapor and clouds are the major contributors to Earth's greenhouse effect, but a new atmosphere-ocean climate modeling study shows that the planet's temperature ultimately depends on the atmospheric level of carbon dioxide.
What moderates changes in temperature on the surface?
Water moderates changes in temperature on the surface.
What role does our atmosphere play in moderating earth’s temperature?
The Atmosphere and Earth's Temperature Gases in the atmosphere surround Earth like a blanket. They keep the temperature in a range that can support life. The gases keep out some of the Sun's scorching heat during the day. At night, they hold the heat close to the surface, so it doesn't radiate out into space.
What are the three main factors that determine the temperature of Earth?
For the most part, the temperature of Earth is determined by three factors: the amount of sunlight Earth receives the amount of sunlight Earth reflects, and therefore does not absorb, and atmospheric retention of re radiated heat. 8.
How does carbon regulate Earth’s temperature?
According to the theory, carbon dioxide controls temperature because the carbon dioxide molecules in the air absorb infrared radiation. The carbon dioxide and other gases in the atmosphere are virtually transparent to the visible radiation that delivers the sun's energy to the earth.
Which layer regulates Earth’s temperatures by absorbing heat?
The Troposphere The air is very well mixed and the temperature decreases with altitude. Air in the troposphere is heated from the ground up. The surface of the Earth absorbs energy and heats up faster than the air does. The heat is spread through the troposphere because the air is slightly unstable.
How does the Earth self regulate temperature?
The carbon cycle plays a key role in regulating Earth's global temperature and climate by controlling the amount of carbon dioxide in the atmosphere. The greenhouse effect itself is a naturally occurring phenomenon that makes Earth warm enough for life to exist.
What factors control temperature variation around the globe?
The four natural factors which cause temperature fluctuation are latitude, altitude, distance from the sea, and ocean currents.
- Latitude. Latitude is an important factor in distinguishing the variation of temperature from place to place. …
- Altitude. …
- Distance From The Sea. …
- Oceanic Current.

How does the atmosphere keep the Earth warm?
Climate Change > What is the Greenhouse Effect? Earth's atmosphere keeps much of the Sun's energy from escaping into space. This process, called the greenhouse effect, keeps the planet warm enough for life to exist. The atmosphere allows about half of the Sun's heat energy (50%) to reach Earth's surface.
What factors affect temperature in the atmosphere?
Factors Affecting the Air Temperature

- Clouds and rains:
What are the main factors that influence temperature?
The temperature characteristics of a region are influenced by natural factors such as latitude, elevation and the presence of ocean currents. The precipitation characteristics of a region are influenced by factors such as proximity to mountain ranges and prevailing winds.
What are the 4 main factors that affect Earth’s temperature?
Sun provides energy for living organisms, and it drives our planet's weather and climate by creating temperature gradients in the atmosphere and oceans.
- Atmospheric Circulation. …
- Ocean Currents. …
- Global Climate. …
- Biogeography.
How does water regulate the Earth’s temperature?
Ocean currents act much like a conveyer belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth's surface.
What is in the ionosphere?
The ionosphere is a shell of electrons and electrically charged atoms and molecules that surrounds the Earth, stretching from a height of about 50 km (30 mi) to more than 1,000 km (600 mi). It exists primarily due to ultraviolet radiation from the Sun.
What is the role of troposphere?
The troposphere provides several important benefits: it holds nearly all of the water vapor in the Earth's atmosphere, regulates temperature and produces weather. All weather phenomena occurs here, like Wind belts, Precipitation, Cyclone etc which are the source for life on Earth.
What is regulation of the Earth?
'Regulation' introduces the ways in which the biogeochemical cycles of the Earth system are self-regulated, how they are coupled to the Earth's climate, and how scientists study this regulation.
How does the global carbon cycle regulate temperature?
The carbon cycle plays a key role in regulating Earth's global temperature and climate by controlling the amount of carbon dioxide in the atmosphere. The greenhouse effect itself is a naturally occurring phenomenon that makes Earth warm enough for life to exist.
Which is a control of temperature?
Thermostats (or temperature controls) are devices that are used to sense and regulate the temperature of the air, a liquid such as water, or another process.
What are controls of temperature of weather?
The controls of temperature are: Latitude (angle of Sun) – Chapter 2. Differential heating of land and water (they heat up/cool down differently) Ocean Currents.
Which gas keeps the Earth warm?
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).
What causes the Earth’s temperature to rise?
Greenhouse Gases Carbon dioxide, methane, and nitrous oxide concentrations are now more abundant in the earth's atmosphere than any time in the last 800,000 years. These greenhouse gas emissions have increased the greenhouse effect and caused the earth's surface temperature to rise.
What are the factors that control temperature distribution on Earth?
Factors that Affecting Controlling Temperature Control
- The latitude of the place.
- The altitude of the place.
- Distance from the sea.
- The air- mass circulation.
- The presence of warm and cold ocean currents.
- Local aspects.

What is temperature affected by?
The temperature of the air is caused by the combination of air, water, and land working together. Those three factors heat and cool areas at different rates. Temperature also varies by the time of day, the season, or even the year. When weather people talk about temperature, they are talking about a mean temperature.
How does water maintain temperature?
The body water has an important role as a thermoregulator, regulating the overall body temperature by helping dissipate heat. If the body becomes too hot, water is lost through sweat and the evaporation of this sweat from the skin surface removes heat from the body.
What do El Nino mean?
El Niño means Little Boy, or Christ Child in Spanish. South American fishermen first noticed periods of unusually warm water in the Pacific Ocean in the 1600s. The full name they used was El Niño de Navidad, because El Niño typically peaks around December. El Niño can affect our weather significantly.
What is the temperature in the ionosphere?
In the ionosphere, radiation from the sun is so powerful that it ionizes, or breaks electrons free from different atoms present in the atmosphere. Due to fluxes in solar radiation, temperatures in the ionosphere vary from 200 Kelvin (or -99 degrees Fahrenheit) to 500K (or 440 degrees Fahrenheit).
Is thermosphere and ionosphere same?
The thermosphere is the layer in the Earth's atmosphere directly above the mesosphere and below the exosphere. Within this layer of the atmosphere, ultraviolet radiation causes photoionization/photodissociation of molecules, creating ions; the thermosphere thus constitutes the larger part of the ionosphere.
What is the role of stratosphere?
The stratosphere is where you'll find the very important ozone layer. The ozone layer helps protect us from ultraviolet radiation (UV) from the sun. In fact, the ozone layer absorbs most of the UV radiation the sun sends to us. Life as we know it wouldn't be possible without this layer of protection.
