| Question | Answer |
|---|---|
| a super continent that existed about 300 million years ago, when all of Earth's landmasses were joined together before they were separated by oceans | Pangea |
| Heat from the Earth's core creates slow-moving currents in the mantle | Convection |
| the theory that continents have moved over Earth's surface throughout geological time | Continental drift |
| the process where rock layers are bent or warped due to compressional stress | Folding |
| cycles of hot rock rising and cooler rock sinking in the Earth's interior MOM: Thick layer of rock located between the Earth's crust and core, it makes up about 84% of the Earth's total volume. | mantle |
| the scientific theory that the Earth's outer layer (lithosphere) is divided into large, moving plates that float on the semi-fluid layer beneath them (asthenosphere) | Plates |
| occurs when tectonic plates collide, causing the Earth's crust to be pushed up and crumple MOM: A significant elevation of the Earth's surface, typically characterized by steep slopes and a peak or summit. | Mountain |
| the theory that the Earth's outer shell is broken into large, rigid plates that move. MOM: a large persistent body of ice that forms on land moves slowly due its weight | Glaciers |
| Earth's central layer that drives geological processes | Core |
| the scientific theory that the Earth's outer layer, the lithosphere, is divided into several large, rigid plates that move over the semi-fluid asthenosphere below | Plains |
| the process of breaking down rocks, soils, and minerals at or near the Earth's surface into smaller pieces (sediments) through physical and chemical interactions with air, water, temperature changes | Weathering |
| the loss of crust from a plate during subduction and the effect of surface (like water and wind) on the tectonic stress of the Earth's crust MOM: the removal of surface material from the Earth's crust, primarily soil and rock debris. It is a geological process that occurs at the Earth's surface and part of the rock cycle. | Erosion |
| the accumulation of debris, such as dust, shells, and ash, that forms layers on Earth's surface, particularly in sedimentary basins created by plate tectonic processes | Sediment |
| a landform created by river sediment, while plate tectonics is the geological theory describing the movement of Earth's lithospheric plates. | Delta |
| a geological process where one tectonic plate moves under another and sinks into the Earth's mantle | Subduction |
| an astronomical event that occurs twice a year (around March 20 and September 23) when the Sun appears to be directly above the Earth's equator | equinox |
| the scientific and cultural shift that occurred when the theory became widely accepted in the 1960s MOM: When an object moves around another, like the Earth goes around the Sun. | revolution |
| A regular, repeating, curved path an object in space follows around another due to gravity. | orbit |
| the specific type of movement where tectonic plates spin on an axis | rotation |
| day of the none of the two times a year when the sun is at its farthest north or south of the celestial equator, which results in the longest or shortest year MOM: The time or date when the sun reaches its maximum or minimum, which makes the longest and shortest days of the year(June and December) | solstice |
