Earth’s rotation is the main reason for the Coriolis effect. The effect deflects anything that flies or flows over a long distance above the ground, proportionate to Earth’s spin direction. Even storms can be a result of the rotation; hence, they do not form similarly everywhere on Earth.

Solar heating of the Earth’s surface is uneven because land heats faster than water, and this causes air to warm, expand and rise over land while it cools and sinks over the cooler water surfaces.

The answer is due to uneven heating of the Earth by the sun. When the earth orbits the sun, the center of the Earth gets more direct sunlight than the poles. This is exacerbated by the Earth’s tilt. Since the center of the Earth gets more sunlight, it is consistently hotter than other parts of the Earth.

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.

Convection currents in the magma drive plate tectonics. Heat generated from the radioactive decay of elements deep in the interior of the Earth creates magma (molten rock) in the aesthenosphere. The crust is recycled back into the aesthenosphere.

Convection works by areas of a liquid or gas heating or cooling greater than their surroundings, causing differences in temperature. These temperature differences then cause the areas to move as the hotter, less dense areas rise, and the cooler, more dense areas sink.

Convection currents transfer heat from one place to another by mass motion of a fluid such as water, air or molten rock. The heat transfer function of convection currents drives the earth’s ocean currents, atmospheric weather and geology.

Heat is a concept that is important to understand in various engineering fields. It is particularly relevant for civil, mechanical and chemical engineers because heat transfer plays a key role in material selection, machinery efficiency and reaction kinetics, respectively.

Controlling the temperature of food is extremely important in ensuring that food is safe to eat, and you must ensure that food is always cooked, cooled, chilled or reheated properly to minimise the risk of harmful levels of bacteria in the food that you sell.

The measurement of body temperature can help detect illness. It can also monitor whether or not treatment is working. A high temperature is a fever.

Top 5 ways body heat is lost

• Evaporation – Body heat turns sweat into vapor.
• Convection – Heat loss by air or water moving across the skin surface.
• Conduction – Direct contact with an object.
• Radiation – The body radiates (like a fire — you can feel heat without being inside the fire).

The body loses heat through: Evaporation of water from your skin if it is wet (sweating). If your clothing is wet, you will also lose some body heat through evaporation and through respiration (breathing) when the body temperature is higher than 99°F (37°C). The body loses about 2% of its heat through air conduction.
