Chapter 17 Plate Tectonics Test

Identify the three types of plate boundaries. Using the word list fill in the blanks on the picture with the word that matches the picture. Convergent Divergent Transform Divergent Convergent Transform Identify the three types of volcanoes. Using the word list provided match the type of volcano with the picture. Shield Stratovolcano Cinder Cone Cinder Cone Shield Stratovolcano Identify the type of seismic waves in the picture. Using the word list match the type of seismic wave to the picture below. p waves s waves surface waves surface waves p waves s waves Describe the three different types of volcanoes. Using the word bank drag and drop the descriptions that best describe the type of volcano. Stratovolcano Steep Sides Built from alternating layers of ash and lava. Shield Gently sloping sides Built up from layers of runny lava. Cinder Cone Short steep sides Built from layers of ash and cinders High viscosity magma and high gas pressure will cause which type of eruption? Dangerously explosive with large ash plumes and pyroclastic flows. Fire Fountains of lava and ash. Quiet eruptions with only runny lava. Shield volcanoes usually only which type of eruption? Dangerously explosive with large amounts of thick lava and ash clouds. Quiet eruptions with very little ash and mostly slow moving or runny lava. Medium sized eruptions with some ash and lava. What are the signs that might be present before an earthquake or volcanic eruption? Sort the list of terms into the correct column. Earthquake They occur with little or no warning. Volcano Ground swelling. Large amounts of gases released. An increase in volcanic activity. Large amounts of smoke and ash released. Ground tremors. What are some of the negative effects caused by earthquakes and volcanoes? Sort the list of negative effects caused by earthquakes and volcanoes into the column that they match up with the best. Earthquake Man made structures get knocked down. Land moves up or down. Tsunamis can form. Flooding can occur. Volcano Man made structures can be buried or burned down. Forests can be leveled. Airplanes are grounded. Lahars can form from melted snow and water. The thickness, stickiness, or how easily a liquid flows is referred to as... density viscosity hardness Which layer of the Earth do convection currents occur? crust inner core mantle What causes the crustal plates to move? Earthquakes Volcanoes Convection Currents Which of the following is not a type of crust? continental oceanic mountainic What is a convection current? Draw a picture of a convection current. Use the color red to show the areas that are hot and use blue to show the areas that are cold. What is the name for process that causes one plate to sink under another at a convergent plate boundary? Subduction Island Arc Rift What mineral found in lava causes some lava to be very thick when there is a lot of it or very thin when there is very little of it? Silica Carbon Granite Read the following passage about tectonic plate boundaries and fill in the blanks as you go, word bank provided. The border between two tectonic plates is called a boundary. All the tectonic plates are constantly moving — very slowly — around the planet, but in many different directions. Some are moving toward each other, some are moving apart, and some are sliding past each other. Because of these differences, tectonic plate boundaries are grouped into three main types.A convergent boundary occurs where two plates are pushing toward each other.A divergent boundary marks two plates that are moving apart from each other.A transform boundary occurs where two plates slide past each other. Which continent does not touch any part of the Ring of Fire? Africa Asia South America Sea-floor spreading, middle ocean ridges, and rift valleys all form along which type of plate boundary? Divergent Convergent Transform Mountains, subduction, and trenches all form along which type of plate boundary? Divergent Convergent Transform How can scientist figure out where the epicenter of an earthquake is located? Find the difference in arrival time between p-waves and s-waves at three different seismic stations and draw overlapping circles that represent the distance the seismic waves have travelled. Fly in an airplane over the area they think the earthquake occurred and look for signs like fallen down trees and houses. Use a satellite to measure how much the ground has moved up and down during the earthquake and using those measurements to see how far the waves have travelled.
