Back

Inertia is the tendency of an object to remain at rest or in uniform motion in a straight line unless acted upon by an external force.

Front

What layer includes the crust (rocky)?

Back

The lithosphere includes the crust and the uppermost part of the mantle.

Front

What two factors impact the strength of the force of gravity between two objects?

Back

The strength of the force of gravity between two objects is impacted by their mass and the distance between them.

Front

True or False: Sea-floor Spreading adds new material to the ocean floor?

Back

True, sea-floor spreading does add new material to the ocean floor.

Front

What is the phase of the moon for letter f?

Back

Waning Gibbous.

Front

Define mass.

Back

Mass is a measure of the amount of matter in an object, typically measured in kilograms.

Front

What is the definition of gravity?

Back

Gravity is the force that attracts two bodies towards each other, depending on their masses and the distance between them.

Front

What is the difference between the lithosphere and asthenosphere?

Back

The lithosphere is the rigid outer layer of the Earth, while the asthenosphere is the semi-fluid layer beneath it that allows for tectonic movement.

Front

What is the role of the mantle in Earth's structure?

Back

The mantle is the thick layer of rock between the Earth's crust and core, playing a crucial role in tectonic activity and heat transfer.

Front

What is a lunar phase?

Back

A lunar phase is the appearance of the illuminated portion of the Moon as seen from Earth, which changes over a cycle of about 29.5 days.
