Answer:
Abyssal Hill
Explanation:
The given words/phrases are directly related to the seafloor spreading process.
In the case of divergent plate motion, plates move in the opposite direction. Due to this, the thickness of the lithosphere decrease and with the increasing time, it results in the eruption of magma at the seafloor. In the ocean basin, these magmas erupt along the mid-oceanic ridge, and in the continental areas, it leads to the formation of a rift and later forms a rift valley.
Some of the segments of the mid-oceanic ridge in the oceans are quite gentle with no roughness along the slope and some segments are steep and rough. It occurs because of the differences in the spreading rate, and this is commonly known as oceanic rise. The rocks that are formed at the mid-oceanic ridge are the youngest of all other rocks.
The odd one here is the abyssal hill, which is formed generally at the seafloor. When the areas at the abyssal plains are comprised of large deposits of sediments forming a hill, then it is called an abyssal hill. It is not related to the seafloor spreading. It is simply a feature of the ocean floor.
Explanation:
The rainforests typically have high biodiversity i.e it has large covers of flora and fauna.
The tropical rainforests are considered to be the oldest biome on earth and that is why they have high biodiversity also there fact is the geographical area of these rainforests are pretty enormous and widespread across the globe.
the tropical rainforests provides equitable climate i.e good amount of rainfall and warm temperature which is a optimum conditions for plants and animal species to survive and also features the best conditions for regular food supplies and growth in natural biodiversity.
many different sources of food and types of shelters are also available in the tropical rainforest, fulfilling the conditions for a vast varieties in natural biodiversity. another important factor that the situations arises in this areas makes way for the new species such as natural disturbance and presence of mountain regions makes home for the refugee species to survive and live.
so these are the reasons why rainforests are typically so biodiversed.
plants and animals ecology in the rainforest has not been in the perfect condition which use to be some decades back it is worsening with time and is a matter of concern.
Tropical rainforests loss is a major environment concern today as because of global climate change has caused major deforestation in the tropical areas. people's influence on the rainforest is also a big problem to watch for.they have started clearing these huge forest cover for wood for furniture and for agriculture and cattle grazing. apart from these issues extinction of species due to global warming has also taken place.
Increase in green house gases and change in natural water cycle have started effecting the natural environment of these rainforests and so tropical rainforests today is big environment concern, as plants and animal's ecology has been disturbed.and losing of natural habitat.
Asthenosphere is the answer of this question. It best describes the all above mention properties.
Asthenosphere is the the upper layer of the earth's mantle, below the lithosphere, in which there is relatively low resistance to plastic flow and convection is thought to occur.
