SCIENCE (help me please) 1. What substances make up the inner core?

2. What is the structure of the inner core?

3. What is the structure of the outer core?

4. Explain the composition of the mantle.

5. What is the role of the asthenosphere?

1. The core is made almost entirely of metal specifically, iron and nickel.

2. The structure of the inner core iron and nickel.

3.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.

4.In terms of its constituent elements, the mantle is made up of 44.8% oxygen, 21.5% silicon, and 22.8% magnesium. There's also iron, aluminum, calcium, sodium, and potassium. These elements are all bound together in the form of silicate rocks, all of which take the form of oxides.

5.The asthenosphere is now thought to play a critical role in the movement of plates across the face of Earth's surface.

Explanation:

explanation:

the universal gravitation equation. since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. if the mass of one of the objects is doubled, then the force of gravity between them is doubled.
