volcanoes
Where two plates move away from each other is a ________________.
Divergent boundary.
What type of plate boundary could cause a valley to form between two mountains?
Divergent boundary
Molten rock that reaches Earth's surface is called ________________.
lava
The laying down or settling of sediment is ________________.
deposition
Circulation within fluids caused by differences in density and thermal energy is called __________________.
convection
Where one plate slides under another
subduction

Continental Plates
Long Answer: State the theory of Plate Tectonics in your own words.
The Earth's crust is broken into large rigid pieces that move in relation to one another.
Long Answer: Contrast mid-ocean ridges with folded mountains.
Mid-ocean ridges are long narrow mountains formed by magma at divergent boundaries and are under he ocean. Folded mountains are formed by crust pushing into each other at convergent boundaries with NO subduction.
Infer why most earthquakes and volcanoes occur along plate boundaries.
Most Earthquakes and volcanoes form along plate boundaries because that is where most of the movement energy of tectonic plates is released. Energy released results in earthquakes. When magma is released between two plates at a boundary, this forms a volcano.
The Mississippi River is the second-longest river in the United States. It begins as a small steep, stream in Minnesota and becomes larger and wider as it travels southward toward Mississippi. It empties into the Gulf of Mexico. Explain how the beginning and end of the Mississippi River might change the land.
Near the top, because it is steeper, the river has more energy and thus causes more erosion than it does near its mouth. As the river moves over the land, it erodes its channel and carries the sediment to other places. This erosion makes the river channel wider. When the river empties into the ocean (the Gulf), it also loses energy and deposits sediment to form a delta.
Plates that are covered in sea water are called ______________________.
Oceanic plates
