Answer:
Surface currents in the ocean are driven by global wind systems that are fueled by energy from the sun. Patterns of surface currents are determined by wind direction, Coriolis forces from the Earth’s rotation, and the position of landforms that interact with the currents. Surface wind-driven currents generate upwelling currents in conjunction with landforms, creating deepwater currents.
Currents may also be caused by density differences in water masses due to temperature (thermo) and salinity (haline) variations via a process known as thermohaline circulation. These currents move water masses through the deep ocean—taking nutrients, oxygen, and heat with them.
Occasional events such as huge storms and underwater earthquakes can also trigger serious ocean currents, moving masses of water inland when they reach shallow water and coastlines. Earthquakes may also trigger rapid downslope movement of water-saturated sediments, creating strong turbidity currents.
Finally, when a current that is moving over a broad area is forced into a confined space, it may become very strong. On the ocean floor, water masses forced through narrow openings in a ridge system or flowing around a seamount may create currents that are far greater than in the surrounding water, affecting the distribution and abundance of organisms as well as the scientists and their equipment seeking to study these organisms.

Answer: The city was the place where everything first started.
<h2>
Following theories can be put up about how hominids evolved:</h2>
- <u>The theory of unused organs:</u>
As the methods that the hominids used to find their food changed, they stopped using some organs of their bodies. As the use of these organs stopped, their bodies evolved to eliminate those organs.
- <u>The theory of improved posture:</u>
As the hominids started relying on their legs for the purpose of locomotion and started using their hands for other purposes, their posture went on becoming more and more erect.
- <u>The theory of improved comprehension:</u>
Along with the development of other body parts, the brain of the hominids also developed to become more efficient. This made the hominids develop the ability of comprehension.

Answer:
b. lower price increases the real incomes of buyers, enabling them to buy more.
Explanation:
The law of demand states that;
-the higher the price, the lower the quantity demanded.
- the lower the price, the higher the quantity demanded.
This law is true considering the fact that consumers tends to buy more when the price is low and vice versa.
One of the most important factor in determining the quantity demanded of a product is the price of the product itself. It means consumers tends to demand for more when the price is low.
When price of a product reduces, the real income of buyers will have effect thus enable them to buy more.
