TE 4th 6weeks Review
Review for Newton's Laws, Plate Tectonics, Topography, and Satellite
Question | Answer |
---|---|
Newton's 1st Law | Law of Inertia |
Newton's 2nd Law | Law of Acceleration |
Newton's 3rd Law | Action -Reaction |
Newton's 1st Law/Law of Inertia definition | an object in motion will remain in motion and an object at rest will remain at rest until acted upon by another force |
Acceleration definition | speeding up, slowing down, or changing direction |
unbalanced force | the reason things change what they are doing |
When a ball is at rest and you push it to a friend is an example of what law? | Newton's 1st Law |
Convection definition | warm air rises then cools and sinks back down |
Cause of currents | caused by the uneven heating of the Earth due to Earth's tilt |
Depostition result | can cause waterways to become shallower and narrower |
Coriolis Effect definition | deflection of objects and wind and ocean currents due to the Earth's rotation on its axis |
Contour Interval definition | The distance between two contour lines |
Steeper slope is shown by | The closer the contour lines the steeper the slope |
Divergent Plate Boundary movement | when tectonic plates move apart |
Effect of Divergent Plate Boundary | mid-ocean ridges, rift valleys, valcones, sea-floor spreading |
Convergent Plate Boundary movement | when tectonic plates come together or converge |
Effect of Convergent Plate Boundary | folded mountain ranges, trenches, and earthquakes |
Subduction Convergent Boundary movement | more dense crust is pushed under less dense crust and re-melted/re-cycled into the Earth's mantle |
Transform Plate Boundary movement | plates slide past each other |
Effect of Transform Boundary | earthquakes and faults |
Formula for Force | Force = Mass x Acceleration |
How to calculate mass | Mass = Force ÷ Acceleration |
How to calculate acceleration | Acceleration = Force ÷ Mass |
Evidence of Pangea | Plants and Fossils of identical species on continents separated by oceans |
Result of sea-floor spreading | oceanic plates move apart allowing magma to fill the gap and form ridges and volcanoes |
forward forces must equal backward forces | What must be true in order for a moving object to continue moving forward at a constant speed |
the smaller object | A small object and a large object are moving at the same speed, which object will require less force to stop? |
Newton's 3rd Law example | When two plate boundaries collide there is an equal and opposite force |
keep sediment out of roadways and rivers | vegetation on sloped areas of land is important because they____________ |
Warmer water temperature | produce more severe hurricanes |
unbalanced force due to gravity | In our inertia day lab, we caused a pen resting on top of a round hoop to drop into a bottle by quickly removing the hoop. Why did the pen drop? |
How are hurricanes fueled? | Warm water vapor when it evaporates |
