Foldables Volcanoes Make the following Foldable to compare and contrast the characteristics of explosive and quiet volcanic eruptions.
Foldables Fold one sheet of paper lengthwise.
Foldables Fold into thirds.
Foldables Unfold and draw overlapping ovals. Cut the top sheet along the folds.
Foldables Label the ovals Explosive Eruptions, Both, and Quiet Eruptions, as shown.
Foldables Construct a Venn Diagram As you read the chapter, list the characteristics unique to explosive eruptions under the left tab, those unique to quiet eruptions under the right tab, and those characteristics common to both under the middle tab.

Reviewing Main Ideas 1 Volcanoes and Earth’s Moving Plates • Volcanoes can be dangerous to people because they can cause deaths and destroy property. • Rocks in the crust and mantle melt to form magma, which is forced toward Earth’s surface. When the magma flows through vents, it’s called lava and forms volcanoes.
Reviewing Main Ideas 1 Volcanoes and Earth’s Moving Plates • Volcanoes can form over hot spots or when Earth’s plates pull apart or come together.
Reviewing Main Ideas 2 Types of Volcanoes • The three types of volcanoes are composite volcanoes, cinder cone volcanoes, and shield volcanoes. • Shield volcanoes produce quiet eruptions. Cinder cone and composite volcanoes can produce explosive eruptions. • Some lavas are thin and flow easily, producing quiet eruptions. Other lavas are thick and stiff, producing violent eruptions.
Reviewing Main Ideas 3 Igneous Rock Features • Intrusive igneous rock bodies such as batholiths, dikes, and sills form when magma solidifies underground. • Batholiths are the most massive igneous rock bodies. Dikes and sills form when magma squeezes into cracks. • A caldera forms when the top of a volcano collapses, forming a large depression.
Chapter Review Question 1 Bits of rock or solidified lava dropped from the air are called __________. A. basalt B. composites C. silicas D. tephra
Chapter Review Answer The answer is D. Tephra varies in size from ash to large blocks.
Chapter Review Question 2 Which type of volcano is steep-sided and formed from tephra falling to the ground? A. basaltic B. cinder cone C. composite D. shield
Chapter Review Answer The answer is B. When tephra falls to the ground, it forms a cinder cone volcano.
Chapter Review Question 3 Which type of volcano is broad with gently sloping sides? A. cinder cone B. composite C. granitic D. shield
Chapter Review Answer The answer is D. Quiet eruptions of basaltic lava spread out in flat layers and form shield volcanoes.
Chapter Review Question 4 Which of these is the largest intrusive igneous rock body? A. batholith B. dike C. sill D. volcanic neck
Chapter Review Answer The answer is A. Batholiths are the largest of the intrusive igneous rock features.
Chapter Review Question 5 What was the primary cause of the loss of life when Krakatau erupted in 1883? A. ash B. temperature drop C. toxic gases D. tsunamis
