The correct answer is (a) Solar Energy

The difference in temperature between the equator and pole of the earth results in formation of wind patterns. The difference in absorption of solar energy leads to buoyancy forces which results in rotation of earth. This rotation of earth causes the wind flow. Hence, the solar energy causes wind to flow which ultimately serves as a source of mechanical energy in wind.

How can a rise in temperature cause a change in a polar ecosystem
Dvinal [7]

Sea levels would rise.

Increase in temperature (for example due to global warming) increases the rate of melting of polar ice.

Consequently, the sea levels of the polar ecosystem would increase.

In addition, the melting of the ice caps also increases the temperature of the water in the oceans. As a result, the water expands which also increases the sea levels.

sesenic [268]

Answer:

A. 50, 88, 145, 227

Explanation:

The correct option would be option A.

<u>When something grows exponentially, it means the growth increased at a high rate. More specifically, each rate of increase results in more or less doubling of the preceding rate. For example, if the current value of growth rate is 2 for a substance that is growing exponentially, the next growth rates will be 4, 8, 16, etc.</u>

<em>In this particular illustration, the only option that best fit into an exponential system is option A in which the growth rate more or less doubles each time from 50 to 88, from 88 to 145, and then from 145 to 227.</em>

What is the difference between a true rib.a false rib and a floating rib
ivann1987 [24]

True rib : the first seven ribs attach to the sternum (the breast bone) in the front and are known as true ribs (or sternal ribs)

False ribs: the lower five ribs do not directly connect to the sternum and are known as false ribs  

Floating ribs :The floating ribs are less stable and risk breaking because they have only one attachment  

Dorsally to the vertebrae and have very thin bone tissue locked in muscle as they extend  

Laterally.
