Write questions in which you ask about underlined parts
•A divergent boundary occurs when two tectonic plates move away from each other. Along these
boundaries, lava spews from long fissures and geysers spurt superheated water. Frequent earthquakes
strike along the rift. Beneath the rift, magma—molten rock—rises from the mantle. It oozes up into
the gap and hardens into solid rock, forming new crust on the torn edges of the plates. Magma from
the mantle solidifies into basalt, a dark, dense rock that underlies the ocean floor. Thus at
divergent boundaries, oceanic crust, made of basalt, is created.

Correct answers
•How many tectonic plates move away from each other when a divergent boundary occurs?
•Where does lava spew from?
•What strikes along the rift?
•Where is new crust formed?
•What does magma from the mantle solidify into?
•What is created at divergent boundaries?

Find the synonyms for the following expressions: a) to bend, b) not smooth or flat, c) a long
narrow valley in the ground under the sea, d) line of something,
•When two plates come together, it is known as a convergent boundary. The impact of the two
colliding plates buckles the edge of one or both plates up into a rugged mountain range, and
sometimes bends the other down into a deep seafloor trench. A chain of volcanoes often forms
parallel to the boundary, to the mountain range, and to the trench. Powerful earthquakes shake a
wide area on both sides of the boundary.

Use the following words in the correct form so that they fit in the gap: a) ocean, b) solid, c)
dense, d) converge
•If one of the colliding plates is topped with ______ crust, it is forced down into the mantle
where it begins to melt. Magma rises into and through the other plate, ________ into new crust.
Magma formed from melting plates solidifies into granite, a light colored, low-_________ rock that
makes up the continents. Thus at __________boundaries, continental crust, made of granite, is
created, and oceanic crust is destroyed.

•If one of the colliding plates is topped with oceanic crust, it is forced down into the mantle
where it begins to melt. Magma rises into and through the other plate, solidifying into new crust.
Magma formed from melting plates solidifies into granite, a light colored, low-density rock that
makes up the continents. Thus at convergent boundaries, continental crust, made of granite, is
created, and oceanic crust is destroyed.

Choose a, b or c.
•Two plates sliding past each other forms a transform plate boundary. Natural or human-made
structures that cross a transform boundary are offset—split into pieces and carried in opposite
directions. Rocks that line the boundary are pulverized as the plates grind along, creating a
linear fault valley or undersea canyon. 1. ____ the plates alternately jam and jump against 2.
______, earthquakes rattle through a wide boundary zone. 3. ______convergent and divergent
boundaries, no magma is formed. 4. ______, crust is cracked and broken at transform margins, but is
not created or destroyed.
•
1.a) like, b) however, c) as
2.a) themselves, b) each other, c) each another
3.a) in contrast to, b) in comparison, c) similarly
4.a) however, b) Nevertheless, c) thus
