EARTH SCIENCE PRACTICE EXAMINATION
2026 QUESTIONS WITH ANSWERS
GRADED A+
◍ plate tectonics.
Answer: the theory that pieces of Earth's lithosphere are in constant motion,
driven by convection currents in the mantle
◍ continental drift.
Answer: the hypothesis that states that the continents once formed a single
landmass, broke up, and drifted to their present locations
◍ earthquake.
Answer: The shaking that results from the movement of rock beneath Earth's
surface
◍ orbit.
Answer: The path of an object as it revolves around another object in space.
◍ volcano.
Answer: a weak spot in the crust where magma has come to the surface
◍ lithosphere.
Answer: the solid, outer layer of the earth that consists of the crust and the
rigid upper part of the mantle
◍ pahoehoe.
Answer: a hot, fast-moving type of lava that hardens to form smooth,
ropelike coils
◍ prominence.
Answer: A loop of gas that protrudes from the sun's surface, linking parts of
sunspot regions.
, ◍ magma.
Answer: molten rock beneath the earth's surface
◍ corona.
Answer: The outermost region of the sun's atmosphere.
◍ compression.
Answer: the type of stress that occurs when an object is squeezed
◍ aa.
Answer: a slow-moving type of lava that hardens to form rough chunks;
cooler that pahoehoe
◍ spectrograph.
Answer: An instrument that separates light into colors and makes an image
of the resulting spectrum.
◍ law of superposition.
Answer: The geologic principle that states that in horizontal layers of
sedimentary rock, each layer is older than the layer above it and younger
than the layer below it.
◍ viscosity.
Answer: the resistance of a gas or liquid to flow
◍ convection current.
Answer: the movement of a fluid, caused by differences in temperature, that
transfers heat from one part of the fluid to another
◍ anticline.
Answer: an upward fold in rock formed by compression of Earth's crust
◍ strike-slip fault.
Answer: a type of fault where rocks on either side move past each other
sideways with little up or down motion
◍ Hubble's law.
Answer: states that the farther away a galaxy is, the faster it is moving away
