1 CST Review Standard 3Plate Tectonics operating over geologic time has changed the patterns of land, sea, and mountains on Earth’s surface.Know the features of the ocean floor (magnetic patterns of land, sea, and mountains on Earth’s surface.Know the principal structures that form at the three different kinds of plate boundaries.Know how to explain the properties of rocks based on the physical and chemical conditions in which they formed, including plate tectonic processes.Know there are two kinds of volcanoes: one kind with violent eruptions producing steep slopes and the other kind with voluminous lava flows producing gentle slopes.Know the explanation for the location and properties of volcanoes that are due to hot spots and the explanation for those that are due to subduction.
2 Which of the following provides evidence for plate tectonics? Sea floor topography.Ocean currents.Coriolis effect.Atmospheric temperatures.
3 The youngest rocks on the ocean floor are typically located near what feature? A midocean ridge.A continental shelf.An abyssal plain.A subduction trench.
4 A rift valley is evidence of which kind of plate boundary? convergentdivergenttransformuniform
5 The convergence (convergent) of two continental plates would produce Island arcs.Rift valleys.Folded mountains.trenches.
6 Which of the following is most responsible for the formation of new crust at the edge of a tectonic plate?Mountain building at a continent-continent convergent boundary.Magma rising up from the mantle at a divergent boundary.Two tectonic plates sliding past one another at a transform boundary.Subduction of one oceanic plate uner another at a convergent boundary.
7 It is generally true that igneous rocks Contain primarily evaporites.Can be scratched with a penny.Normally contain fossils.Are composed of silicate materials.
8 Cooling rates of igneous rocks can be estimated by comparing rocks’ Crystal sizes.composition.density.Chemical reactivity.
9 Which of the following would most likely produce a fragmental (broken up) sedimentary rock? Magma fractured on the ocean floor.Calcite crystallized from seawater.Gravel deposited in a silt bed.Limestone dissolved in cave formation.
10 Energy is transferred between Earth’s surface and the atmosphere by these three mechanisms. A: Conduction, convection, and radiation
11 Define reversed polarity. A magnetic field that points south.
