Questions and Answers

Match the following terms related to earthquake events with their accurate definitions.

Focus = Region where energy is initially released during an earthquake. Epicenter = Point on the Earth's surface directly above the focus of an earthquake. Seismic Waves = Vibrations spreading outwards from the earthquake focus. Benioff Zones = Regions where deep earthquakes occur, where the crust subducts back into the mantle.

Match the following types of energy transfer with their corresponding descriptions.

Conduction = Energy transfer through a solid; the material itself does not move. Convection = Energy transfer through a fluid; hot, less dense material rises, while cooler, denser material sinks. Radiation = Energy transfer between points without requiring material.

Match the following Earth science concepts with their brief descriptions.

Plate Tectonics = Theory that the Earth's lithosphere is broken into rigid plates moving on the asthenosphere. Hotspots = Regions of continuous volcanism over time, associated with mantle plumes. Inclination = Angle from the horizontal, dependent on latitude.

Match the following definitions related to seismic waves with their respective terms.

Seismic Waves = Vibrations spreading outwards from the earthquake focus. Body Waves = Seismic waves traveling outward in all directions. Surface Waves = Seismic waves traveling along the Earth's surface. Signup and view all the answers

Match the following terms related to Earth's structure with their descriptions:

Lithosphere = The cool, rigid outermost layer of Earth (approximately 100 kilometers thick). Asthenosphere = A relatively weak layer beneath the lithosphere, allowing for gradual flow. Mesosphere = A more rigid layer beneath the asthenosphere. Divergent Boundaries = Boundaries where tectonic plates move apart. Signup and view all the answers

Match the following types of tectonic plate boundaries with their characteristics:

Convergent Boundaries = Boundaries where tectonic plates collide or one slides beneath the other, often occurring where continental crust is involved. Transform Fault Boundaries = Boundaries where plates slide past each other. Divergent Boundaries = Boundaries where tectonic plates move apart. None of the above = Not applicable.

Match the following Earth Science concepts with their definitions:

Earth System Science = The study of Earth as an interconnected system, examining interactions between its components. Atmosphere = The mixture of gases surrounding Earth. Hydrosphere = All of Earth's water (oceans, lakes, underground water, snow, and ice - cryosphere). Biosphere = All living organisms and undecomposed organic matter on Earth.

Match the following geological concepts with their descriptions:

Paleomagnetism = Using the magnetic properties of rocks to determine their latitude and orientation at the time of formation. Orientation = The direction in which magnetic minerals align themselves, pointing towards the magnetic pole. None of the above = Not applicable.

Study Notes

Earth Science Concepts

Inclination: Angle from the horizontal, depends on latitude.
Benioff zones: Regions where very deep earthquakes occur, where crust subducts back into the mantle.
Plate tectonics: Theory that Earth's lithosphere (outer, rigid shell) is broken into dozens or so rigid plates that move relative to one another on the hotter, more plastic asthenosphere.
Conduction: Movement of energy through a solid body. The material itself does not move.
Convection: Movement of energy through a fluid body. The material moves and carries the heat. Hot, less dense material rises upward through a fluid and is replaced by cooler, more dense material = convection currents.
Radiation: Movement of energy between points that does not require any material at all.
Hotspots: Places where there has been continuous volcanism for a long period of time – sites of mantle plumes.
Focus: Region where energy is first released.
Epicenter: Point on Earth's surface, directly above focus.
Seismic waves: Vibrations spreading out from focus.
Body waves: Waves which travel outward in all directions.
Surface waves: Waves which travel on Earth's solid surface.
Seismic gaps: Places where earthquakes have not occurred in a long time, and elastic strain has been increasing.
