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."

It holds the intense heat as well as pressure that helps is maintaining the iron and nickel in the molten state.

Explanation:
Otter attacks on humans are rare. Prophylactic antibiotic therapy after an animal bite is indicated for clinically significant injuries and a weakened immune response. '
The otter's main barrier against heat loss is an airtight barrier. The otter vigorously rubs its paws together to seal the air next to its skin. It can also breathe air through its fur. Underwater, they look silver because of the oxygen in Turkey. Sea otters swim on their backs when they sleep.
They can wrap themselves in seaweed or hold each other's hands while they sleep to stay there and float out to sea. Sea otters have three main strategies to escape from predators: run, hide in the kelp where they live, or surface. They can also use their powerful teeth when they encounter other sea otters.
