schools of fish
brittle stars
pale, blind shrimp
giant tube worms
deep-sea corals

Question 4

Part B: Why might these animals live near these particular seafloor features?

Question 5

Match each cause (left side) to each effect (right side)

Draggable item		Corresponding Item
Tectonic plates collide		islands are formed
Tectonic plates move apart very slowly		a trench is formed
One tectonic plate slides under another		seafloor spreading
Seafloor spreading		continental drift
Water seeps into the earth’s crust and is heated by magma		hydrothermal vents are formed
Seamount emerges from the ocean’s surface		mountains are formed

Question 6

On page 84, the author uses a simile when describing the mountain chain formed by mid-ocean ridges, saying it is like the stitching on a baseball.

Explain what this simile means.
