Answer:
Sea breezes occur during hot, summer days because of the unequal heating rates of land and water. During the day, the land surface heats up faster than the water surface. Therefore, the air above the land is warmer than the air above the ocean. Now, recall that warmer air is lighter than cooler air. As a result, warm air rises. Therefore, the warmer air over the land surface is rising. As the warm air over the land is rising, the cooler air over the ocean is flowing over the land surface to replace the rising warm air. This is the sea breeze and can be seen at the top of the following image. The bottom of the following image illustrates the land breeze that occurs at night. Recall that the land surface cools quicker than the water surface at night. Therefore, the warmer air over the ocean is buoyant and is rising. The denser cool air over the land is flowing offshore to replenish the buoyant warm air and is called a land breeze.
Answer:
D
Explanation:
kinetic energy is motion energy, all other choices are forms of potential energy since they are not moving.
Answer:
C. High heat capacity
Explanation:
Water helps maintain temperature of communities close to it. It does this by absorbing heat emanating from the communities around the water bodies such as rivers and seas in a process known as convection current. In exchange for absorbing the heat from the land, the river or sea supplies the land with cool sea breeze. This exchange will help maintain temperature at a close range.
Answer:
The relationship between the warming of the earth’s northern latitude and ice is a practical example of a positive feedback on the earth system.
Explanation:
A positive feedback is a process that brings about an increase in the process of interaction in the earth activities The warming of the northern latitude which is responsible for generating more heat through sunlight with time, usually results in an increase in the melting of ice bodies in the ocean by movement. This activity is regarded as positive because it is associated with an increase in the process. This process is directly proportional to the exchange activities that takes place and often leads to an equilibrium in the earth system.
