Answer. Heat from the Earth’s core and radiation from the Sun is transferred to the surface of the Earth by conduction. Contact of the atmosphere with these warm surfaces transfers thermal energy, which then heats upthe rest of the air through convection.

There are three ways heat is transferred into and through the atmosphere:

• radiation.
• conduction.
• convection.

Air expands on heating because the particles of air on becoming warm, move away from each other and take up more space. So we can say that air on becoming hot occupies more space. Since the particles move away from each other, the air becomes less dense and lighter in weight.

Hot air is lighter than cold air. The reason fr this is when air gets heated up it expands and becomes less dense than the air surrounding it also the distance between the molecules increases. So the less dense air floats in the much denser air just like ice floats on water as ice is less dense than water.

As air warms up, the molecules start to vibrate and bump into each other, increasing the space around each molecule. Because each molecule uses more space for motion, the air expands and becomes less dense (lighter). The amount of space the air takes up shrinks, or reduces the air pressure.

As the air grows colder the average speeds of all of the gasses in the air slow down, but there is still plenty of room for water vapor. In a similar way, some vapor molecules in the air are going slowly enough to be pulled into the water by intermolecular forces when they hit the water; they condense into liquid.

What happens to air temperature when work is done on the air to compress it? When air is allowed to expand it cools, when is compresses it warms. the decrease of air temperature with altitude, or of water temperature with depth.

Water reflects most solar radiation that reaches its surface back to the atmosphere. Since land absorbs more solar radiation the land surface retains more heat as do the vegetation for energy. Thus, land surfaces warm more quickly than water.

The specific heat of water is greater than that of dry soil, therefore water both absorbs and releases heat more slowly than land. Large bodies of water tend to moderate the temperature of nearby land due to the high heat capacity of water.

It takes less energy to change the temperature of land compared to water. This means that land heats and cools more quickly than water and this difference affects the climate of different areas on Earth.

Compared to air or land, water is a slow conductor of heat. That means it needs to gain more energy than a comparable amount of air or land to increase its temperature. That means that, once heated, a body of water will hold onto that heat for a much longer period of time than either air or land.

• Tijuana, Mexico, the most murderous city in the world per capita.
• Cape Town, South Africa, the most murderous city in the world by death toll.
• Caracas, Venezuela, the most murderous city in South America.

However, darkness can make the risks of swimming in the ocean significantly more dangerous. It isn’t safe to swim in the ocean at night. Swimming in the ocean at night can pose a greater risk than swimming during daylight hours, especially for inexperienced swimmers.
