Use this 20-question quiz to review Dynamic Earth Part 1 for the 2.20 unit test in high school earth science. Practice key ideas like Earth's layers, plate motion, earthquakes, volcanoes, and the rock cycle, then see where you need more study. Use it as a quick check before class or while you study.
Study Outcomes
- Understand key geological processes that shape the Earth's surface.
- Analyze the role of plate tectonics in forming continents and ocean basins.
- Apply observational skills to identify various landforms and geological features.
- Evaluate evidence supporting theories of dynamic Earth changes.
- Interpret geological maps and diagrams to assess natural processes.
2.20 Unit Test: Dynamic Earth Part 1 Cheat Sheet
- Earth's Layers - Earth is a giant onion made of crust, mantle, and core, each boasting unique textures and temperatures. Cracking these layers helps us unravel geological mysteries like volcanic eruptions and plate shifts.
- Plate Tectonics Theory - Earth's lithosphere is broken into nimble plates that dance around the globe, crashing, pulling apart, or sliding past each other. Recognizing where these boundaries lie teaches us why earthquakes, volcanoes, and mountain ranges pop up where they do.
- Convection Currents - Deep in the mantle, heat-driven currents act like a slow-motion lava lamp, nudging tectonic plates into motion. This engine underpins the Earth's ever-changing surface, fueling continental drift without us even noticing.
- Plate Boundaries - Plates can diverge like best friends moving apart or converge like two cars colliding, and they can even slide past each other in a transform dance. Each boundary type creates unique features - from mid-ocean ridges and mountain chains to fault lines ready to rumble.
- Earthquakes - When stress overloads rock, it snaps and shakes the ground! The epicenter is our street-level lookout, while the focus hides deep beneath the crust at the quake's birthplace.
- Volcanoes - Magma finds its spotlight at convergent borders, divergent splits, and mysterious hotspots, belching lava, ash, and drama. Spotting these volcanic zones helps volcano-watchers predict where eruptions might explode next.
- Rock Cycle - Rocks are chameleons, shifting between igneous, sedimentary, and metamorphic forms through melting, squishing, and weathering. This epic recycling saga proves Earth's forever in motion.
- Seafloor Spreading - Beneath the waves, new crust is born at mid-ocean ridges as plates pull apart and magma fills the gaps. This process is solid proof that the seafloor itself spreads over time.
- Subduction Zones - At subduction zones, one plate bows down and dives beneath another, carving deep trenches and igniting volcanic arcs. These dramatic interactions reveal how Earth recycles its crust at gigantic scales.
- Continental Drift - Over eons, continents have drifted across the globe like cosmic floaters, fitting like pieces in a supercontinent jigsaw. Alfred Wegener's continental drift theory rocked the scientific world and set the stage for plate tectonics.
