Plate Boundary/Tectonics

What is the difference between oceanic and continental plates?

• Oceanic plates are denser and thinner than continental plates, which are thicker and less dense.

• Oceanic plates are lighter and thicker than continental plates, which are thinner and denser.

• Oceanic plates are the same density as continental plates, but larger in size.

• Oceanic plates are less dense and thinner than continental plates, which are thicker and denser.

What is a divergent plate boundary?

• A type of boundary where two tectonic plates move towards each other, leading to the formation of mountains.

• A type of boundary where two tectonic plates move away from each other, often resulting in the formation of new crust, such as mid-ocean ridges.

• A boundary where tectonic plates slide past each other, causing earthquakes.

• A boundary that forms when tectonic plates remain stationary and do not interact.

What is the Himalayan mountain range an example of?

• A transform boundary

• A continent-ocean convergent boundary

• A continent-continent convergent boundary

• A divergent boundary

What forms at a convergent boundary between a continental plate and an oceanic plate?

• Earthquakes

• Volcanoes

• Mountain ranges

• Ocean trenches

What is a convergent plate boundary?

• A boundary where two tectonic plates move away from each other, leading to the formation of new crust.

• A boundary where two tectonic plates slide past each other without significant vertical movement.

• A boundary where two tectonic plates move towards each other, leading to one plate being forced below another, which can create mountains or volcanic activity.

• A boundary where tectonic plates remain stationary and do not interact.

What is a fault?

• A fault is a type of rock formation found in mountains.

• A fault is a fracture in the Earth's crust along which movement has occurred, commonly found at transform boundaries.

• A fault is a geological feature that indicates the presence of water underground.

• A fault is a volcanic eruption that occurs beneath the Earth's surface.

What is subduction?

• Subduction is the process where one tectonic plate moves under another plate and sinks into the mantle.

• Subduction is the process where two tectonic plates collide and create mountains.

• Subduction is the process of tectonic plates sliding past each other without interaction.

• Subduction is the process where tectonic plates break apart and form new oceanic crust.

What is a rift valley?

• A lowland region formed by the movement of tectonic plates apart, often at divergent boundaries.

• A highland area formed by the collision of tectonic plates.

• A flat plain created by volcanic activity.

• A mountainous region formed by the uplift of tectonic plates.

What is the asthenosphere?

• A solid layer of the Earth's crust that supports tectonic plates.

• The semi-fluid layer of the Earth's mantle that lies beneath the lithosphere, allowing tectonic plates to move.

• The outermost layer of the Earth that is composed of solid rock.

• A layer of the Earth's atmosphere that contains weather patterns.

What is the lithosphere?

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

• The inner core of the Earth that is liquid and composed mainly of iron and nickel.

• The layer of the Earth that is primarily composed of gases and is found above the atmosphere.

• The semi-fluid layer beneath the lithosphere that allows tectonic plates to move.
