Convection
Explanation:
Heat is a form of thermal energy borne as result of thermal energy. It is observed as temperature differences between places.
There are different types of heat transfer:
- Conduction
- Convection
- Radiation
Conduction is a heat transfer which involves the actual movement of the collision of the molecules of the medium.
Convection is a heat transfer in fluids by their movement from areas of higher to places of lower heat.
Radiation is heat transfer using electromagnetism and does not involve molecules of the medium
The process of heat transfer from ground to the air touching it is convection. It involves particles of the air.

Injecting salt crystals over the ocean to grow cloud droplets has been proposed in efforts to make the clouds brighter thereby affecting the radiation budget. The light of the sun shines on Earth, some of that light is reflected by the clouds back to space and some of the light reaches the earth and warms our planet. The earth and the hot oceans emit infrared radiation (IR), which we feel as heat. That IR "light"; returns to space through the atmosphere. Most are trapped by greenhouse gases, which keep the earth warm. Soon after, the IR radiation returns to space. Scientists call this "energy budget of the Earth" this cycle of incoming and outgoing energy.

Complete question is;
Which of the following object would take you the greatest amount of force to accelerate.
A) a soccer ball with a mass of 0.5 kg
B) a refrigerator with a mass of 200 kg, C) a bike with a mass of 25 kg
D) a car with a mass of 5,000 kg,
Answer:
D) a car with a mass of 5,000 kg
Explanation:
Formula for force is;
F = ma
Where;
F is force
m is mass
a is acceleration
Now, Force is directly proportional to the acceleration and mass.
Thus, the higher the mass, the greater the force.
Thus, the object that will require the most force is the one that has the highest mass.
Looking at the options, the one with the highest mass is option D.
It obtains a neutral pH (7). The combination of a strong acid and a strong base results in a neutral pH. The pH of HCl is about 1, and the pH of NaOH is 14.
