Question 1

Which layer of Earth is composed primarily of iron and nickel and is responsible for generating Earth's magnetic field?

Accepted Answer

Outer core

Answer

Earth's outer core is a liquid layer of iron and nickel whose movement generates the planet's magnetic field through convection currents.

Question 2

What type of rock is formed when molten magma cools and solidifies?

Accepted Answer

Igneous

Answer

Igneous rock forms directly from the cooling and solidification of magma or lava, making it the primary rock type formed from molten material.

Question 3

The theory of plate tectonics explains that Earth's lithosphere is divided into large sections called:

Accepted Answer

Tectonic plates

Answer

The lithosphere is divided into tectonic plates that float on the semi-fluid asthenosphere and move relative to one another, driving geologic activity.

Question 4

Which type of boundary occurs when two tectonic plates move away from each other?

Accepted Answer

Divergent boundary

Answer

A divergent boundary is where two plates separate from each other, allowing magma to rise and form new crust, as seen at the Mid-Atlantic Ridge.

Question 5

What is the primary cause of the seasons on Earth?

Accepted Answer

Earth's axial tilt of 23.5°

Answer

Earth's axial tilt of 23.5° causes different hemispheres to receive varying amounts of direct sunlight throughout the year, creating seasonal changes.
