| Question | Answer |
|---|---|
| What is the Marian's trench? | The Mariana's Trench is the deepest natural trench in the world, created by the subduction of the Pacific plate under the Mariana plate |
| What is the mantle? | The mantle is the mostly-solid bulk of the Earth's interior. It lies between Earth's dense, super-heated core and it's thin outer layer- the crust. |
| What is the hottest part of the Earth? | The inner core is the hottest part of the Earth |
| What is the theory of continental drift? | Continental Drift is a theory that explained how continents move around Earth's surface |
| What is Pangea? | Pangaea refers to the super continent that existed approximately 225 million years ago |
| What is the Ring Of Fire? | The Ring Of Fire is an area of frequent seismic and volcanic activity and notably contains 452 volcanoes |
| What is a mega quake? | A mega quake is a very powerful earthquake, generally with a richer scale value exceeding 7 |
| What is folding? | Folding occurs when heat and pressure are applied to rock layers in the Earth's crust, causing bending and layering of the original strata (layers). |
| What is faulting? | Faulting occurs when two parallel plates move alongside one another, often causing earth quakes |
| What is a seismograph? | A seismograph is a tool used to measure the intensity of an earthquake |
| What is the lithosphere? | The lithosphere is the rigid outer part of the Earth, consisting of the crust and upper mantle. it floats on the asthenosphere |
| What is igneous? | Igneous is a type of rock formed through the cooling and solidification of magma or lava |
| What is sedimentary? | Sedimentary rocks are formed by the accumulation of layer upon layer of sediments over time |
| What is the subduction zone? | The subduction zone is located at the meeting of two plates, where one plate is forced under the other |
| What is oceanic crust? | Oceanic crust underlies the ocean, it is thinner, but more dense than continental crust because of the pressure of the water above it |
| How many ecozones does Canada have? | Canada has 15 ecozones, which are all identified by factors such as climate, soil, vegetation and animals |
| What is a tsunami? | A tsunami is a series of ocean waves that send surges of water, sometimes reaching heights of over 100 feet (30.5 meters), onto land. Often caused by undersea earthquakes |
| What is a ritcher scale? | A ritcher scale is the scale of numbers used to tell the size of earthquakes (ranging from 1 - 10) |
| What is an example of a subduction zone? | The Ring of Fire |
| What are the effects of plate movement? | 1) Volcanoes and island chains 2) Mountain Building 3) Earthquakes, tsunamis and mudslides 4) Ocean trenches 5) Seafloor spreading + expansion of ocean bottom 6) Formation of mineral deposits |
| What is the order of ears from first to present? | PreCambrian Era, Paleozoic Era, Mesozoic Era, Cenozoic Era |
| What is the era we are currently in? | We are currently in the Cenozoic Era |
| What is the longest era? | PreCambrian era is the longest era |
| What is the oldest era? | PreCambrian Era is the oldest era |
| What is one geological and biological event if the PreCambrian Era? | Geological: Water rained from the atmosphere and created oceans Biological: Single-cell organisms appear |
| What is one geological and biological event from the Palezoic Era? | Geological: Super continents Biological: Largest mass extinction, fungi appears |
| What is one geological and biological event from the Mesozoic Era? | Geological: Innuitans and Rocky Mountains formed Biological: Age of dinosaurs |
| What is one geological and biological event from the Cenozoic Era? | Geological: an ice age Biological: Humans come to exist |
| Earth's parts starting from middle: | Inner core (solid), Outer core (liquid), Mantle, Crust |
| How is the inner core the hottest part of the Earth but is also solid? | It is still solid because of the amount of pressure but on it from the other parts of the earth, it has no room to move |
| What are Canada's 7 landform regions? | Innuatian mountains, Western Cordillera, Appalachians, Great Lakes and St. Lawrence Lowlands, Hudson Bay and Arctic Lowlands, Interior Plains, Canadian Shield |
| What landform do you live in? | I live in the Great Lakes and St. Lawrence Lowlands |
| What is the biggest landform region in Canada? | The Canadian Shield is the biggest landform region in Canada |
| What is the region has large oil and gas deposits? | The interior Plains have large oil and gas deposits |
| What region has the Rocky Mountains? | The Western Cordillera is the region with the Rocky Mountains |
| What region is the coldest? | The Innuatian Mountains is the coldest region |
| What highlands region has the oldest, most eroded mountains? | The Appalachians are the oldest, most eroded mountains |
| What region has polar bears, boggy marshes and lots of bugs? | The Hudson Bay and Arctic Lowlands has lots of polar bears, boggy marshes, and lots of bugs |
| What is the mist population region? | The Great Lakes and St. Lawrence Lowlands is the most populated region |
