Layers of the Earth Checkpoint

Front

What is a Spring Tide?

Back

A Spring Tide is a higher than normal tide that occurs when the Earth, Moon, and Sun are aligned, resulting in greater gravitational pull.

Front

What causes the INNER core of the Earth to be solid?

Back

The INNER core is solid due to the intensely high pressure that exists at that depth, despite the high temperatures.

Front

What are Tides?

Back

Tides are the daily changes in ocean water levels caused by the gravitational pull of the Moon and the Sun.

Front

When do Neap Tides occur?

Back

Neap Tides occur when the Earth, Sun, and Moon are at a 90-degree angle to each other, resulting in lower tidal ranges.

Front

What is the Earth's Mantle?

Back

The Mantle is Layer 3 of the Earth, located between the crust and the outer core, composed of semi-solid rock.

Front

What is the difference between Spring Tides and Neap Tides?

Back

Spring Tides are higher tides that occur during full and new moons, while Neap Tides are lower tides that occur during the first and third quarters of the moon.

Front

What role does the Moon play in ocean tides?

Back

The Moon's gravitational pull is the primary force that causes ocean tides, creating bulges in water levels.

Front

What is the composition of the Earth's INNER core?

Back

The INNER core is primarily composed of iron and nickel and is solid due to extreme pressure.

Front

What is the Lithosphere?

Back

The Lithosphere is the rigid outer layer of the Earth, consisting of the crust and the uppermost part of the mantle.

Front

What is the Asthenosphere?

Back

The Asthenosphere is the semi-fluid layer of the mantle located beneath the lithosphere, allowing for tectonic plate movement.
