Plate Boundaries

What is a Convergent Boundary?

• A type of plate boundary where two tectonic plates are moving away from each other.

• A type of plate boundary where two tectonic plates are moving toward each other, often resulting in subduction or collision.

• A type of plate boundary where tectonic plates slide past each other without significant vertical movement.

• A type of plate boundary that forms when tectonic plates are stationary.

Continent-Ocean Convergent Boundary

• A boundary where two continental plates collide and form mountains.

• A boundary where a dense oceanic plate collides with and subducts beneath a less dense continental plate, forming volcanoes.

• A boundary where tectonic plates slide past each other without significant interaction.

• A boundary where an oceanic plate pulls away from a continental plate, creating new ocean floor.

What is a Divergent Boundary?

• A type of plate boundary where two tectonic plates are moving away from each other, resulting in the creation of new crust.

• A type of plate boundary where two tectonic plates collide, causing one plate to be forced under the other.

• A type of plate boundary where two tectonic plates slide past each other without significant movement up or down.

• A type of plate boundary that occurs when tectonic plates are stationary and do not interact.

What is a Subduction Zone?

• The region where two tectonic plates collide and one is forced beneath the other.

• The area where tectonic plates slide past each other without significant vertical movement.

• The location where tectonic plates are moving apart, creating new crust.

• The zone where tectonic plates are stationary and do not interact.

What is the lithosphere?

• The rigid outer part of the Earth, consisting of the crust and upper mantle, which is broken into tectonic plates.

• The layer of the Earth that is molten and flows beneath the lithosphere.

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

• The atmosphere surrounding the Earth that contains gases essential for life.

What is Subduction?

• The geological process at convergent boundaries where one tectonic plate moves under another and is forced down into the mantle.

• The process of two tectonic plates moving away from each other.

• The formation of mountains due to the collision of tectonic plates.

• The movement of tectonic plates along a transform boundary.

What is Plate Tectonics?

• The scientific theory that Earth's outer shell is divided into several large plates that glide over the mantle.

• A method of measuring the Earth's temperature.

• A type of rock formation found in mountains.

• The study of weather patterns and climate change.

What is a Transform Boundary?

• A type of plate boundary where two tectonic plates slide horizontally past one another without creating or destroying crust.

• A type of plate boundary where tectonic plates move away from each other, creating new crust.

• A type of plate boundary where tectonic plates collide, causing one plate to be forced under another.

• A type of plate boundary where tectonic plates are stationary and do not interact.

What is Seafloor Spreading?

• The process at mid-ocean ridges where new oceanic crust is formed through volcanic activity and then gradually moves away.

• The movement of tectonic plates towards each other, causing earthquakes.

• The process of erosion of oceanic crust due to wave action.

• The formation of new oceanic islands through volcanic eruptions.

What is the Continental Crust?

• The thin, dense part of Earth's crust that forms the ocean floor.

• The relatively thick, less dense part of Earth's crust that forms the large landmasses and is primarily composed of granite.

• The layer of the Earth that is molten and flows beneath the crust.

• The outermost layer of the Earth that is composed entirely of basalt.
