Answer:
The marshes are defined as the type of wetland where the water covers the ground surface for a long period of time. Here, the trees are absent and are mostly dominated by the grasses and other small herbivore plants. They are commonly formed in delta type of environment where the rivers adds water into the seas. It forms an isolated and distinct ecosystem.
The marshes in nature, behaves like a filtration process as the vegetation that are present in marshes takes up more amount of nutrients for their growth and expansion. But, if it does not use up these excess nutrients then it cause water pollution comprising of nitrogen and phosphorous.
They also plays an important role in the reduction of damages that are caused by a flood.
The marshes are sometimes seasonal and it occurs when the height of the river level is relatively high, and it floods the grassland areas.
The marshes are of three types-
(1) Tidal salt marshes
(2) Tidal freshwater marshes
(3) Inland freshwater marshes.
Plants have these because root nodules<span> are formed when nitrogen fixing bacteria called "rhizobia" start to enter the cells of a host </span>plant<span>. Rhizobia normally live inside of the soil and they </span>can<span> exist without a host </span>plant<span>.</span>
Answer:
The landform that will form is a mid-ocean ridge.
Explanation:
When tectonic plates move away from each other they form a divergent plate boundary. At this type of boundary, as the plates move away, a gap starts to open up gradually. This gap becomes wider and wider over time and the crust is made much less thick, which in turn presents a good opportunity for the magma to come out on the surface.
Because the crust is weaker and thinner, the magma manages to rise through it and rich the surface relatively easily. As it does, the magma reaching the surface, or rather the bottom of the ocean, it solidifies in the water and as more and more magma comes out it piles up. By piling up and constantly creating new rock an underwater mountain chain starts to form and this type of mountain chain is known as a mid-ocean ridge.
