Question | Answer |
---|---|
What is Igneous Rock? | Any type of rock can be MELTED in the Earth’s crust. It needs HEAT. |
What is Sedimentary Rock? | Rock that forms from other ERODED rock. |
What is Metamorphic Rock? | When rock in the crust gets pushed under another tectonic plate, metamorphic rock can form. It needs HEAT and PRESSURE. |
What is Radiation? | Electromagnetic waves from the Sun travels through our atmosphere and hits the surface (land, water). |
What is Convection? | The transfer of energy through the movement of hot or cool fluids (air and water). Hot air rises and cool air sinks. |
What is Conduction? | The transfer of heat energy by two or more objects in contact with each other. |
What is Sea Breeze? | Sea Breeze: During the day, the land is hotter than the ocean. A breeze moves from the cool air over water (land pressure) to the warm air over land (low pressure). |
What is Land Breeze? | Land Breeze: At night, the ocean is warmer than the land. A breeze moves from the cool air over land (HIGH pressure) to the warm air over the ocean (LOW pressure). |
What is Weathering? | Wind, ice, gravity, and water BREAK ROCK apart, creating sediment. |
What is Erosion? | When the sediment is MOVED to another place by wind, ice, gravity, water. |
What is Deposition? | When the sediment carried by wind, ice, gravity, water is deposited (LAID DOWN) in another location. |
What is the Law of Superposition? | In horizontal layers of sedimentary rock, each layer is older than the layer above it and younger than the layer below it. |
What is the Tectonic Plates Theory? | It explains how Earth's subterranean movements create major landforms. |
What type of tectonic plates form volcanoes? | Convergent Plates |
What type of tectonic plates cause Earthquakes? | Convergent and Transform Plates. |
What are Convergent Tectonic plates? | Where two plates are moving towards each other and colliding. |
What are Divergent Tectonic Plates? | Where tectonic plates are moving away from each other. |
What are Transform Plates? | Where two plates move (and rub) against each other in opposite directions. |
What is Weather? | Can change between a few minutes or hours. |
What is Climate? | Takes very long time to change. Is measure as averages. Ex. The average amount of rain. The average temperature, etc. |
What is found in the Biosphere? | All living things on earth. |
What is found in the Cryosphere? | All of the frozen ice on earth. |
What is found in the Atmosphere? | Layers of gas that surround the earth’s surface. |
What is found in the Hydrosphere? | All of the liquid water on earth |
What is found in the Geosphere? | The soil, rock, and land at the surface of the Earth. |
What are the layers of Earth? | Crust: where living things are. Mantle: below the crust. It moves very slow. Outer Core: Hot, liquid. Its motion generates Earth's magnetic field. Inner Core: Hot, solid, very dense center of the planet. |
