Plate Motion Quiz- Amplify Lesson 2.4

Imagine Oliver, Priya, and Mia are on a thrilling adventure to understand the mysteries of our planet. They stumble upon a question: What causes the plate motion on Earth?

• Is it due to tectonic activity and volcanic eruptions?

• Could it be convection currents in the Earth's mantle and gravitational forces from the Moon and the Sun?

• Maybe it's earthquakes and meteorite impacts?

• Or could it be magnetic forces and ocean currents?

Answer explanation

The primary cause of plate motion is due to convection currents in the Earth's mantle. As the mantle heats up from the core's heat, it rises until it hits the crust, where it cools, sinks, and is then reheated by the core, creating a cycle that moves the plates. Gravitational forces from the Moon and the Sun also plays a minor role.

Imagine Charlotte, James, and Anika are on a thrilling adventure to understand the mysteries of our planet. They stumble upon a strange phenomenon. Can you guess what it could be, given it's an effect of plate motion?

• volcanic eruptions

• tsunamis

• earthquakes

• landslides

Answer explanation

The question asks about the effects of plate motion. One effect is earthquakes. This is due to the fact that when tectonic plates move, they can cause the earth's crust to shake, resulting in earthquakes. Other effects like volcanic eruptions, tsunamis, and landslides can also occur but the correct answer in this context is earthquakes.

Imagine Abigail, Mason, and Aiden are on a thrilling adventure, exploring the Earth's crust. They stumble upon a place where two plates collide. Can you tell what type of boundary they have discovered?

• convergent boundary

• transform boundary

• divergent boundary

• subduction boundary

Answer explanation

A convergent boundary is formed when two plates collide. This process is due to the motion of tectonic plates. The term 'convergent' means 'coming together', which refers to the action of the two plates. The other options, transform and divergent boundaries, are associated with plates sliding past each other and moving apart, respectively. A subduction boundary is a type of convergent boundary where one plate moves under another.

Imagine Michael, Aria, and Oliver are on a thrilling adventure, exploring the Earth's crust. They come across a place where two plates are moving apart. Can you guess what type of boundary they have discovered?

• divergent boundary

• convergent boundary

• subduction boundary

• transform boundary

Answer explanation

The question asks about the type of boundary formed when two plates move apart. The correct option is 'divergent boundary'. This is because a divergent boundary represents a geological boundary where tectonic plates move away from each other, causing an upwelling of material from the mantle to create new sea floor and continental crust.

Anika, Luna, and Lily are on a thrilling adventure to a volcano! They see molten rock reaching the Earth's surface. What is this process called?

• tectonic shift

• lava flow

• volcanic eruption

• earthquake

Answer explanation

The question asks for the term that describes molten rock reaching the Earth's surface. This process is specifically called a 'volcanic eruption'. It involves the expulsion of molten rock (lava), ash, and gases from a volcano. 'Lava flow' refers to the movement of lava once it has reached the surface, while 'tectonic shift' and 'earthquake' are unrelated to the process described in the question.

Imagine Michael, Ava, and Abigail are superheroes with different powers. Michael has tectonic force, Ava has frictional force, and Abigail has magnetic force. If one of them is responsible for plate motion on Earth, who would it be?

• Michael (tectonic force)

• Ava (frictional force)

• Abigail (magnetic force)

• None of them (gravitational force)

Answer explanation

The force responsible for plate motion is the tectonic force. This is not caused by frictional, magnetic, or gravitational force. Tectonic forces are generated from within the Earth due to the movements in the Earth's lithosphere and asthenosphere, causing the plates to move.

What happens when two plates slide past each other horizontally?

• Transform boundary

• Subduction zone

• Divergent boundary

• Convergent boundary

Answer explanation

The question is asking about the geological event that occurs when two tectonic plates slide past each other horizontally. The correct answer is 'Transform boundary'. This is because at a transform boundary, tectonic plates are neither created nor destroyed, instead, they slide past each other horizontally, causing earthquakes.

Imagine Jackson, James, and Benjamin are on a thrilling adventure to understand the mysteries of our planet. They stumble upon a phenomenon where one tectonic plate is sinking beneath another. What is this exciting process called?

• collision

• uplift

• subduction

• rift

Answer explanation

The process of one tectonic plate sinking beneath another is called subduction. This term describes the movement in the earth's crust where one plate moves under another and sinks into the mantle. The other options, collision, uplift, and rift, are also related to tectonic plates but do not accurately describe this specific process.

Ethan, Oliver, and David are on a thrilling adventure to understand the mysteries of the Earth's crust. They stumble upon a place where two plates are moving towards each other. Can you help them identify what this boundary is called?

• convergent boundary

• subduction zone

• transform boundary

• divergent boundary

Answer explanation

The term for the boundary where two plates are moving towards each other is known as a 'convergent boundary'. It is the place where two or more tectonic plates of the Earth's crust are colliding with each other. It is not a subduction zone, transform boundary or divergent boundary.

Imagine Kai, Anika, and Grace are on a thrilling adventure to explore the Earth's crust. They stumble upon a boundary where two plates are moving away from each other. Can you guess what this boundary is called?

• transform boundary

• divergent boundary

• subduction zone

• convergent boundary

Answer explanation

The term for the boundary where two plates are moving away from each other is known as a divergent boundary. This differs from a transform boundary where the plates slide past each other, a convergent boundary where two plates come towards each other, and a subduction zone where one plate goes beneath another.
