Question

which layer of the earth is responsible for generating earths magnetic field?○ mantle○ outer core○ inner core○ crustplate tectonics is often associated with the formation of mountain ranges. which of the following best explains how the movement of tectonic plates results in the creation of mountains?○ plates collide, forcing the land upward and creating mountains.○ plates slide past each other, eroding the land and forming valleys.○ plates move away from each other, causing the land to sink and form mountains.○ plate tectonics has no direct connection to mountain formation.

Explanation:

For the first question: Earth's outer core is a layer of liquid iron and nickel that flows, creating electric currents which generate the planet's magnetic field. The other layers do not have the necessary properties to produce this field.
For the second question: Mountain ranges form primarily when tectonic plates collide; the compressive force pushes the crust upward, folding and uplifting rock to create mountains. The other options describe plate movements that form valleys, rifts, or are incorrect statements.

Answer:

1. Outer Core
2. Plates collide, forcing the land upward and creating mountains.
