The heating of the Earth’s surface and atmosphere by the sun drives convection within the atmosphere and ocean. This convection produces winds and ocean currents. The greater the pressure differences between a low-pressure area and a high-pressure area, the stronger the winds.

Conduction, radiation and convection all play a role in moving heat between Earth’s surface and the atmosphere. Conduction directly affects air temperature only a few centimeters into the atmosphere. During the day, sunlight heats the ground, which in turn heats the air directly above it via conduction.

Heat radiates from the ground into the lower atmosphere. In conduction, heat moves from areas of more heat to areas of less heat by direct contact. Warmer molecules vibrate rapidly and collide with other nearby molecules, transferring their energy. Heat transfer by movement of heated materials is called convection.

Due to the chemical composition of the earth’s atmosphere, most of the infrared radiation emitted by the warm surface never reaches space. Instead the radiation is reflected or absorbed by compounds known as greenhouse gasses. When these compounds absorb the infrared radiation from the surface, the atmosphere heats up.

Without any greenhouse gases, Earth would be an icy wasteland. Greenhouse gases keep our planet livable by holding onto some of Earth’s heat energy so that it doesn’t all escape into space. This heat trapping is known as the greenhouse effect. Putting so much new CO2 into the air has made Earth warmer.

Make sure the lights are off if you are the last to leave the classroom, take shorter showers, and consume less meat and dairy products are all good ways you can reduce your personal footprint. Taking the time to get involved in conservation efforts in your area is a great way you can help fight climate change.

Practical tips for schools

• Teach children about the three R’s: reduce waste, reuse resources, and recycle materials.
• Organise tree planting days at school and tell children why trees are important to the environment.
• Encourage children to switch off all appliances and lights when not in use.

How does convection affect the weather? Convection within the atmosphere can often be observed in our weather. Stronger convection can result in much larger clouds developing as the air rises higher before it is cooled, sometimes producing Cumulonimbus clouds and even thunderstorms.

Radiation from the warmed upper atmosphere, along with a small amount from the Earth’s surface, radiates out to space. Most of the emitted longwave radiation warms the lower atmosphere, which in turn warms our planet’s surface.

The energy transferred by radiation propagates with the speed of light . In radiation , heat is transferred by electromagnetic waves , which have the fastest speed , so it is the fastest mode of heat transmission .

The correct option is A) Radiation. Radiation is the fastest mode of heat transfer while conduction is the slowest mode of heat transfer.

Heat transfer through convection is a rapid process 3. Out of these three processes radiation is the fastest one. 4. Radiation is the fastest because in this case, the transfer of heat takes place at the speed of light.

Ans: The faster form of payment depends on the urgency and the amount of your transaction. If you have a transaction above Rs. 2 lakh, RTGS is a faster and more effective mode of payment. However, for any payments which are of lower amounts, NEFT is a more efficient mode of payment.

Answer. The direct memory access or DMA mode of data transfer is faster amongst all the mode of data transfer . The device request the cpu through a DMA controller to hold its data ,address and control bus so that the device may transfer data directly to or from memory.

IMPS (Immediate Payment Service) Using IMPS, you can transfer comparatively lower amounts, up to Rs. 2 lakhs, instantly. So, you can think of IMPS as the fund transfer mode that has the best features of both RTGS and NEFT. The IMPS service is offered by the National Payments Corporation of India (NPCI).

This extends Paytm’s leadership in the payments market where UPI P2P (peer-to-peer) apps such as Phone Pe and Google Pay are restricted to ₹2 lakh per transaction. “We offer all-important payment methods and are the only platform where users can pay instantly using NEFT, IMPS, UPI, Wallet, and cards.

Account holders don’t have to wait for days to receive money in their bank accounts as with the help of the latest digital payment systems like NEFT, RTGS, and IMPS, money can be sent and received in an instant anytime from anywhere.

Amount: The maximum amount that can be transferred through IMPS is ₹ 2 lakh. However, there is no prescribed limit for the minimum amount allowed to make an IMPS transaction. Charges: SBI charges ₹ 1 rupee plus GST on transactions valued from ₹ 1,001 to ₹ 10,000.

Yes, you can able to deposit or transfer money (1 Crore) through RTGS system. What is RTGS: The Real Time Gross Settlement, or RTGS, is for high-value transactions. The minimum amount is Rs 2 lakh.

NEFT, RTGS, IMPS Fund Transfer

NEFT transactions done after banking hours will be automated using ‘Straight Through Processing (STP)’ modes by the banks. The existing rule of crediting the beneficiary’s account or returning the transaction (within 2 hours of settlement of the respective batch) to originating bank will continue, RBI said.
