Question | Answer |
---|---|
Oceanic crust has a low density and is made of rock that is rich in silica?? | False. |
The Earth's crust and the rigid, upper part of the mantle forms a layer of Earth called the lithosphere?? | True. |
The three types of Plate boundaries are: Divergent, Convergent, and Transform Boundaries?? | True. |
The continents of the Earth are still moving and drifting apart today?? | True. |
All scientists accepted Wegner's hypothesis of Continental Drift?? | False. |
Tectonic plates are moving everyday?? | True. |
Earthquakes occur everyday?? | True. |
The hypothesized "supercontinent" where all of the continents once formed a single landmass is called?? | Pangea. |
Who came up with the hypothesis of Continental Drift?? | Alfred Wegner. |
New ocean floor is constantly being produced through the process known as?? | Sea-Floor Spreading. |
An underwater mountain chain that formed by sea-floor spreading is called?? | Mid-Ocean Ridge. |
The theory that explains why and how continents move is called?? | Plate tectonics. |
Compared to rocks farther from the ridge, rocks closer to the ridge are?? | Younger. |
The mechanism (process) that verifies (proves) Wegner's hypothesis of Continental Drift is?? | Sea-Floor Spreading. |
Who found the idea of sea-floor spreading?? | Harry Hess. |
How do scientists identify the location of Plate boundaries?? | The location of earthquakes and volcanoes. |
The cycle in which the cooler, denser water sinks and the warmer water rises to the surface to create a cycle is called?? | A Convection cell. |
The boundary between tectonic plates that are moving away from each other?? | Divergent boundary. |
The boundary between tectonic plates that are sliding past each other horizontally?? | Transform boundary. |
The boundary between tectonic plates that are colliding towards each other?? | Convergent boundary. |
As the hot material rises, the cooler denser materials flows away from the hot material, sinking into the mantle to replace the rising magma?? | Mantle Convection. |
Sudden movements in plate tectonics?? | Earthquakes. |
