Question: Which statement best explains why Earth’s outer core is in liquid form?
The iron-nickel alloy melts due to hot temperatures.
The outer core has a tarry consistency.
This region is less dense when compared to the mantle.
This region is under extreme pressure from the weight of other layers.
Answer:
The statement here that bet describes the Earth's outer core is in liquid form " The iron-nickel alloy melts due to hot temperatures."
Explanation:
The outer core of the Earth's is made up of fluid layer which is about 2400 km thick and basically made from iron as well as nickel alloy. This layer lies just above the solid inner core and below it mantle is present. The core of the Earth works like a furnace for the whole composition. It holds the intense heat as well as pressure that helps is maintaining the iron and nickel in the molten state.
Answer: human beings make their very own area of pastime and defy organic and organic selection, in part, via doing so. Alex, beavers are in assessment to human beings. we don't definitely make the comparable dams and nests throughout the time of time. We thoroughly substitute our surroundings.

<u>Answer:</u>
For example, the dinosaurs' fossils helped the scientists to learn about their habits, habitats, etc.
<u>Explanation:</u>
Scientists greatly depend upon existing biological evidences of extinct organisms in the form of 'fossils' to study the earlier life existed within the biosphere and the geosphere.
Fossil research allows researchers to learn a great deal not only about the organisms' live form and behaviour but also the Earth's geosphere and biosphere at that time. Specially, transitional fossils are more apt to study as they demonstrate the transitional states of a fossil between the ancestral type and the descendants' recent form.
