What type of mountain forms from the magma that is created by sea-floor spreading? Volcanic mountains

fossils found on continental coasts, The use of fossils found on continental coasts, the close fit of continental coastlines, and the similarity of rock type on different continents were used as evidence to support what theory? The theory of continental drift

Each line marks a change in __________. elevation

What type of boundary would cause the formation of a trench? Convergent boundary

When the seafloor spreads, what happens? The older oceanic crust moves aways from the mid-ocean ridge, and the new crust forms at the mid-ocean ridge.

Which of the following types of plate boundaries would result in a rift valley?

Seismic waves travel at different speeds and directions in Earth’s interior because Of the way tectonic plates move. Each layer has different physical properties. Sea-floor spreading causes magnetic reversals. The outer core is liquid.

Many scientists believe that convection currents in the asthenosphere between South America and Africa caused the separation of the two continents and the formation of the Mid-Atlantic Ridge. Which diagram best represents the convection currents in the plate tectonic theory? A C B D

The diagram shows how the ocean floor is spreading The diagram shows how the ocean floor is spreading. The new ocean floor made of molten rock is being formed at a mid-ocean ridge. Which best describes where the molten rock comes from? A The crust B Volcanoes under the ocean floor C Masses of land to either side of the ocean D The mantle just beneath Earth’s crust

The asthenosphere has the property of plasticity, which allows the solid mantle to move like a liquid. Which of the following explains how the crust moves in different directions? F Radiation G Convection currents H Geothermal J Conduction

Which of the following statements is not supported by the plate tectonic theory? A Continents move through the seafloor crust. B Locations of volcanoes and earthquakes can be explained. C Seafloor spreading provides evidence to support the plate tectonic theory. D There are three different types of plate boundaries associated with the direction of plate movement.

The lithosphere is Earth’s crust plus the rigid upper part of Earth’s mantle. The map shows plates of the lithosphere. What does the map tell you about the plates? A The plates are all moving in the same direction. B The plates are all the same size. C Plates and continents are different. D Where two plates meet, they always move apart.

Newton’s laws of motion apply to everyday life in a variety of ways Newton’s laws of motion apply to everyday life in a variety of ways. Which one of the followingstatements does not demonstrate Newton’s laws of motion as they relate to plate tectonics? F Plates resist change as in Newton’s law of inertia. G The greater the force, the greater rate of acceleration as in Newton’s law of acceleration. H Volcanoes form from cooled magma as in Newton’s law of acceleration. J Plates exert a force on each other in opposite directions as in Newton’s law of action-reaction.
