Answer 1

Q1.

answer:

If you have spent much time at the beach during the summer at the beach, absorbing UV radiation to darken your skin or just beachcombing, you've probably noticed that at around 3:00 p.m. there often is a strong steady wind blowing in from the water. This steady wind, the sea breeze, is a result of the uneven heating during the daytime between the land and the adjacent water. At night the wind often reverses direction and blows from the land to the water (a land breeze). Land and sea breezes are referred to as direct thermal circulations. Let's examine the sea breeze.

An object will heat up or cool down depending on its total energy budget. If the object gains more energy than it looses, the object warms. How much the object's temperature increases depends on its thermal properties -- heat capacity and heat (or thermal) conductivity. During the day the land, which has a low specific heat and is a poor conductor, heats much more quickly than water. As the land warms up, the air next to it heats by conduction and rises, warming the air above the land by convection. As the air rises it generates a pressure gradient , and thus a pressure gradient force , generating the thermal circulation. To understand this, let's first imagine that the land, sea and the air above them are at the same temperature and that the isobars are parallel. As pressure is defined as the weight of the air molecules above us, the isobars must decrease in magnitude with increasing altitude (Figure 1). In this simplified model, the temperature of the ocean and the air above the ocean are not changing and thus initially no air molecules are moving. As air over the land warms (due to absorption of solar energy, and conduction to a thin air layer above) it rises and there is a vertical displacement of air molecules to a higher altitude (Figure 2). These rising thermals of air change the orientation of the initial isobars.

Answer 2

Explanation:

1) Sea and Land Breezes describe the wind that blows onshore from sea to land during the day and blows offshore in the evening. Why do I care? During the summer, the sea breezes are stronger than in winter because of the large temperature differences between land and ocean water that time of year.

4) Electrical energy is caused by moving electric charges called electrons. ... In power stations, turbines are turned using energy from sources such as heat, wind and moving water. Generators are machines for converting motion energy into electricity

5) They are found in Asia, Australia, Africa, North America and South America. Sahara is the world's largest tropical desert (desert).

6) Equator

Powered by. Any circle drawn around the Earth divides it into two equal halves called hemispheres. There are generally considered to be four hemispheres: Northern, Southern, Eastern, and Western. The Equator, or line of 0 degrees latitude, divides the Earth into the Northern and Southern hemispheres.
