Question

The liquid outer core of the earth is 2300 km thick. A scale model of the layers of the earth has a scale of 1 inch: 500km. How thick is the liquid outer core of the model?

Answer 1

The liquid outer core of the model is 4.6 inches thick.

Step-by-step explanation:

To determine the thickness of the liquid outer core of the model, we need to use the given scale. The scale of the model is 1 inch: 500km. The liquid outer core of the Earth is 2300km thick. We can set up a proportion to find the thickness of the liquid outer core in the model:

1 inch / 500km = x inches / 2300km

Cross-multiplying and solving for x, we get:

x = (1 inch)(2300km) / (500km) = 4.6 inches

Therefore, the liquid outer core of the model is 4.6 inches thick.

Answer 2

Earth's outer core is a fluid layer about 2,400 km (1,500 mi) thick and composed of mostly iron and nickel that lies above Earth's solid inner core and below its mantle. Its outer boundary lies 2,890 km (1,800 mi) beneath Earth's surface.

about 2,400 km
