Answer:
Sea floor spreading-> <u><em>Oceanic ridge and Magma pushing two plates apart</em></u>
Continental drift-> <u><em>Concept of pangaea and Oceanic plates sliding under continental crust</em></u>
Explanation:
Due to the divergent plate movement, the magma come out to the surface, forming the mid oceanic ridge and this separation of plates on the sea floor is known as the sea floor spreading. The magma here pushes the two plates to move apart because of the convection current that generates in the mantle. One example of mid oceanic ridge is the Mid-Atlantic Ridge.
Continental drift refers to the slow and gradual movement of the lithospheric plates over the viscous asthenosphere layer. This motion of continents takes place because of the plate tectonic movement. Due to this plate motion, the denser plate gets subducts beneath the less denser plates. For example, the oceanic crust when collides with a continental crust, it gets subducted because of its higher density. The great supercontinent "pangaea" also formed and separated due to this plate motion.
What happens to the ocean water as it moves from Antarctica to the equator is : ( B ) It becomes less dense and rises to the surface.
<h3>Concept conveyor belt </h3>
The conveyor belt is a system of oceans which transports water and propel deep current of water bodies across the globe based on the differences in water densities.
As the ocean water moves from the Antarctica to the equator the cold ocean water mixes with the warm ocean water at the equator, which makes the water less dense and rises to the surface.
Hence we can conclude that What happens to the ocean water as it moves from Antarctica to the equator is It becomes less dense and rises to the surface.

Answer:
Disruptive selection
Explanation:
According to the infographic that is attached below showing different the three main types of selection that occurs as a result of natural selection taking its course on any population, we can draw our conclusion regarding the information given to us from the question.
From the question above, it states that the finches studied by Darwin are majorly finches with either small beak or large beak which are all adapted to suit the type of food available for the finches in the islands. Whereas, finches with intermediate beaks are favored against.
According to the infographic, disruptive selection can be said to have taken place as extreme traits are favored against intermediate traits on the islands.
During interphase, cell growth occurs
Answer:
Due to the large number of fossils being discovered at that time Darwin proposed that species change over long periods of time.
Explanation:
The theory of Darwin was that the species change in accordance to their environment, thus they develop advantageous traits so that they can be more competitive.
