Question

A. Define the following terms.
1. Heat :
2. Land breeze:
3 Nutrition :
4 troposphere :
5 Atmospheric pressure :
6 thunderstorm :
7 cyclones :​

Answer 1

Answer:

1. Heat is a form of energy. It flows from a body at a higher temperature to a body at a lower temperature.

2. A breeze blowing towards the sea from the land, especially at night, owing to the relative warmth of the sea is called land breeze.

3. Nutrition is nourishment or energy that is obtained from food consumed or the process of consuming the proper amount of nourishment and energy.

4. The lowest layer of the earth’s atmosphere, between the surface of the earth and about 6 to 10 kilometres above the surface is known as troposphere.

5. The pressure exerted by the weight of the atmosphere, which at sea level has a mean value of 101,325 pascals (roughly 14.6959 pounds per square inch) is known as atmospheric pressure.

6. A storm of heavy rain accompanied by lightning, thunder, wind, and sometimes hail is called thunderstorm.

7. A cyclone refers to any low pressure area with winds spiralling inwards. Cyclones rotate clockwise in the Southern Hemisphere and anti-clockwise in the Northern Hemisphere.

Answer 2

Answer:

1) heat is energy in transfer to or from a thermodynamic system, by mechanisms other than thermodynamic work or transfer of matter. The mechanisms include conduction, through direct contact of immobile bodies, or through a wall or barrier that is impermeable to matter; or radiation between separated bodies; or isochoric mechanical work done by the surroundings on the system of interest; or Joule heating by an electric current driven through the system of interest by an external system; or a combination of these.

Heat, energy that is transferred from one body to another as the result of a difference in temperature. If two bodies at different temperatures are brought together, energy is transferred—i.e., heat flows—from the hotter body to the colder.

2) Land breeze, a local wind system characterized by a flow from land to water late at night. Land breezes alternate with sea breezes along coastlines adjacent to large bodies of water. Both are induced by differences that occur between the heating or cooling of the water surface and the adjacent land surface.

3)Nutrition is nourishment or energy that is obtained from food consumed or the process of consuming the proper amount of nourishment and energy. An example of nutrition is the nutrients found in fruits and vegetables. An example of nutrition is eating a healthy diet.

| The process of taking in food and using it for growth, metabolism, and repair. Nutritional stages are ingestion, digestion, absorption, transport, ...

4) The troposphere is the lowest layer of Earth's atmosphere, and is also where nearly all weather conditions take place. ... The total average height of the troposphere is 13 km. The lowest part of the troposphere, where friction with the Earth's surface influences air flow, is the planetary boundary layer.

5) One atmosphere (101.325 kPa or 14.7 psi) is also the pressure caused by the weight of a column of fresh water of approximately 10.3 m (33.8 ft). Thus, a diver 10.3 m underwater experiences a pressure of about 2 atmospheres (1 atm of air plus 1 atm of water). Atmospheric pressure, also called barometric pressure, force per unit area exerted by an atmospheric column (that is, the entire body of air above the specified area). ... Near Earth's surface the pressure decreases with height at a rate of about 3.5 millibars for every 30 metres (100 feet).

6) A thunderstorm, also known as an electrical storm or a lightning storm, is a storm characterized by the presence of lightning and its acoustic effect on the Earth's atmosphere, known as thunder. Relatively weak thunderstorms are sometimes called thundershowers. Thunderstorms result from the rapid upward movement of warm, moist air, sometimes along a front. As the warm, moist air moves upward, it cools, condenses, and forms a cumulonimbus cloud that can reach heights of over 20 kilometres (12 mi).

7) In meteorology, a cyclone is a large scale air mass that rotates around a strong center of low atmospheric pressure. ... Warm-core cyclones such as tropical cyclones and subtropical cyclones also lie within the synoptic scale. Mesocyclones, tornadoes, and dust devils lie within smaller mesoscale.Tropical cyclones form only over warm ocean waters near the equator. ... So basically as the warm air rises, it causes an area of lower air pressure below.
