Can You Pass A Quiz on Earth Science?

Earth is not a perfect sphere; it is slightly flattened at the poles and bulging at the equator due to its rotation.

The crust is the Earth’s outermost layer where all life exists and where we live.

Nitrogen makes up about 78% of Earth’s atmosphere, making it the most abundant gas.

Day and night occur because Earth rotates on its axis approximately once every 24 hours.

The gravitational pull between the Earth and the Moon keeps the Moon in orbit.

Mars is smaller and has less mass than Earth, resulting in a weaker gravitational pull.

The Earth’s outer core is made of liquid iron and nickel, and its movement generates the planet’s magnetic field.

The Pacific Ocean is the largest and deepest ocean, covering more area than all landmasses combined.

Heat from Earth’s interior causes convection currents in the mantle that move tectonic plates.

At transform boundaries, plates slide horizontally past one another, often causing earthquakes.

Igneous rocks form when magma or lava cools and solidifies, either above or below ground.

Earth’s atmosphere protects life by blocking harmful radiation and maintaining a stable climate through the greenhouse effect.

Precession is the gradual change in the orientation of Earth’s axis over thousands of years.

The 23.5° tilt of Earth’s axis causes different parts of the planet to receive more or less sunlight during its orbit, resulting in seasons.

A solar eclipse occurs when the Moon passes between the Earth and Sun, casting a shadow on Earth.
