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.

<u>Answer:</u>
The steps which were involved in the impact theory of lunar formation is a <em>prevailing theory of finding which was supported by all the members of the scientist’s community. </em>
<u>Explanation:</u>
The theory suggested and gave an explanation that the lunar formation was origin or formed when bigger objects smashed into earth. Like any other planet the story of formation of earth is also the same.
<em>Earth was just created by the left overs huge masses of cloud dust and the gasses which were orbiting the young sun at that period.</em>
Answer:
<h3>Ocean salt primarily comes from rocks on land. ... Rocks on land are the major source of salts dissolved in seawater. Rainwater that falls on land is slightly acidic, so it erodes rocks. This releases ions that are carried away to streams and rivers that eventually feed into the ocean.</h3>
