What is a hypothesis?
An evidence-based idea that can be tested by experimentation or investigation, serving as a starting point for scientific inquiry.
A definitive conclusion drawn from a series of experiments.
A random guess made without any prior knowledge or research.
A statement that cannot be tested or proven.
What is Sea-Floor Spreading?
The process where molten rock flows up through a crack at a mid-ocean ridge, creating new ocean floor.
The movement of tectonic plates away from each other.
The sinking of oceanic plates into the mantle.
The formation of mountains due to tectonic plate collision.
What is the hypothesis of Continental Drift?
The theory that continents are fixed in place and do not move.
The hypothesis that all continents were once fused together and have slowly moved apart over time.
The idea that continents are formed by volcanic activity.
The belief that continents are created by oceanic currents.
Lava
Molten rock that has erupted from a volcano and reached Earth's surface.
A type of sedimentary rock formed from compressed sand.
A solid form of water found in glaciers.
A gaseous state of matter found in the atmosphere.
Plate Tectonics
The scientific theory that Earth's lithosphere is broken into large plates that are in slow, constant motion.
A method of measuring the Earth's temperature variations.
A type of rock formation found in mountainous regions.
The process of erosion caused by wind and water.
What does the term Magnitude refer to in geology?
A measure of the size of an earthquake based on the energy it releases.
The depth of an earthquake's focus beneath the Earth's surface.
The distance from the epicenter to the nearest city.
The duration of seismic waves during an earthquake.
What is a Seismic Wave?
A type of wave that travels through water
Vibrations that travel through Earth carrying the energy released during an earthquake or other large-scale geological event.
A sound wave produced by seismic activity
A wave that only travels through the atmosphere
What is Oceanic Crust?
The type of crust found on land, primarily composed of granite rock.
The dense type of crust that is found at the bottom of the ocean, primarily composed of basalt rock.
A type of crust that forms in the atmosphere, composed of various gases.
The outer layer of the Earth that is primarily composed of sedimentary rock.
What is Compression?
A type of stress that squeezes rock until it bends or breaks, which is common at convergent plate boundaries.
A process of increasing the volume of a substance by applying heat.
A method of reducing the size of a material by applying tension.
A technique used in photography to enhance image quality.
What is a Fossil?
The preserved traces or remains of ancient organisms that are found in rock, providing evidence of past life.
A type of rock formed from volcanic activity.
A living organism that has existed for millions of years.
A modern-day animal that has not changed over time.
What is a Tsunami?
A large wave or series of waves produced by a sudden displacement of water, such as an undersea earthquake.
A gentle rise and fall of the ocean's surface caused by the gravitational pull of the moon.
A type of storm surge that occurs during hurricanes and tropical storms.
A phenomenon where water levels rise due to heavy rainfall and flooding.
What is the definition of Epicenter?
The point on Earth's surface located directly above the focus of an earthquake.
The center of a volcanic eruption.
The location where seismic waves are first detected.
The point where two tectonic plates meet.
What is the definition of stress in geology?
The force that acts on rock to change its shape or volume, leading to deformation like folding or faulting.
A measure of the amount of force applied to an object.
The process of weathering and erosion of rocks over time.
The ability of a material to withstand deformation under load.
What is an Ocean Trench?
A shallow area of the ocean where sunlight penetrates
A deep undersea valley that marks the place where a dense oceanic plate is sinking back into the mantle.
A region of the ocean with high temperatures and volcanic activity
A flat area of the ocean floor that is rich in marine life.
What is Pangaea?
A type of dinosaur
The name of the supercontinent that existed millions of years ago when all of Earth's landmasses were fused together.
A famous ancient city
A geological term for a volcanic eruption
What is a Mid-Ocean Ridge?
A long, zipper-like chain of undersea mountains that runs through Earth's oceans where new oceanic crust is formed.
A type of ocean current that circulates warm water around the globe.
A geological formation that occurs when two tectonic plates collide.
A shallow area of the ocean where sunlight penetrates and supports marine life.
What is a theory in science?
A hypothesis that has not been tested
A well-substantiated explanation of some aspect of the natural world that is supported by a vast array of evidence
A simple guess about a phenomenon
An unproven idea that lacks evidence
What is Magma?
A solid rock found in the Earth's crust.
A molten mixture of rock-forming substances, gases, and water that originates from Earth's mantle below the crust.
A type of gas released during volcanic eruptions.
A layer of soil above the Earth's surface.
What is a Transform Boundary?
A boundary where two tectonic plates collide and form mountains.
A boundary where two tectonic plates slip past each other horizontally, which is a common cause of earthquakes.
A boundary where tectonic plates move away from each other, creating new crust.
A boundary that is characterized by volcanic activity and magma formation.
What is Tension?
A type of stress that compresses the crust, making it thicker, common at convergent boundaries.
A type of stress that pulls on the crust, stretching the rock to make it thinner, common at divergent boundaries.
A type of stress that causes the crust to twist and rotate, common at transform boundaries.
A type of stress that has no effect on the crust, remaining neutral.
