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.
