T.7. THE EARTH’S DYNAMICS.
1.- Relate the followings concepts with their definitions and one picture:
1.- Convergent Boundaries
2.- Divergent Boundaries
3.- Transform fault Boundaries
a.- They occur when two plates move laterally in opposite directions
b.- They occur when two plates are moving away from each other
c.- They occur when two plates move towards each other.
2.- Relate the 10 following pictures into the three kind of boundaries of the
previous exercise.
3.- Watch the following video about Plate Boundaries and choose the correct
answer:
1.- Why is there movement in the Earth’s crust?
a.- Because warmer and less dense material rises
b.- Because warmer and more dense material sinks
c.- Because convection causes movement
2.- When the crust moves…
a.- it moves in four different ways
b.- it moves in three different ways
3.- Which one is correct?
a.- together = divergent/ apart = convergent/ side by side = transform
b.- apart = convergent/ together = side by side/ divergent = apart
c.- together = convergent/ apart = divergent/ side by side = transform
4.- Mountains form because of:
a.- convergent boundaries
b.- divergent boundaries
5.- Where is the new crust = a crust factory formed?
a.- in the convergent boundaries

b.- in the divergent boundaries
6.- Volcanoes are formed in:
a.- convergent boundaries with continental- continental collision
b.- divergent boundaries
c.- convergent boundaries with ocean – continental collision
7.- Earthquakes happen in the:
a.- continental boundaries
b.- side by side boundaries
4.- Pay attention to the three following videos about Earthquakes and answer True
or False to the next sentences:
FIRST VIDEO:
1.- The ground under your feet shakes.
2.- This movement is not scary to experience.
3.- In an earthquake things can fall and things can break apart.
4.- Earthquakes can damage buildings and roads, but not utilities or pipe lines.
5.- Only engineers design structures to resist earthquakes.
SECOND VIDEO:
6.- When a tsunami is formed, the earthquake occurs in the water.
7.- The wave created in a tsunami travels at 60 hundred miles per hour.
8.- The wave is bigger when it is close to the coast.
9.- The wave can be one hundred feet tall.
THIRD VIDEO
10.- The earthquake in Japan killed 200 hundred people and another 10 thousand are still missing.
11.- There is only one man recording the video of the earthquake.
12.- The blue bridge is broken down.
13.- There are at least three boats that are totally destroyed.
14.- The houses are very resistant to the earthquake.
15.- The color of the water is blue.
5.- Look at the following illustration. What do the numbers correspond to? Choose
among the following concepts.

LAVA - PIPE - VOLCANIC CONE – CRATER – MAGMATIC CHAMBER –
GASES
6.- Video about Volcanos. Complete with the missing words and relate the meaning
of some of them.
MAGMA - VIOLENTLY - RESTLESS - PACIFIC OCEAN - EARTH - ACTIVE - TECTONIC PLATES - VESUVIOUS HAWAII - INTERIOR - 15 - MOUNTAINS - LAVA
A few hundred years ago, scientists believed that volcanoes were burning
________ of fire. Today we know they are really openings or vents to the hot ______ of
the planet. About _____ hundred volcanoes around the world are classified as active.
Nearly 90 % of these rest in the Ring of Fire, a band circling the _____ ______. Their
location is no accident. While the Earth’s surface looks stable, its crust is made up of a
net of* slabs of rock, like puzzle pieces, but constantly shift. Where these ______
______ interact, volcanoes often form. Friction from shifting plates melts the Earth’s
crust, causing rock beneath the crust to liquefy. This molten rock or ______ then
becomes a volcano by erupting through rifts in the plates. Once magma escapes from
the _____, it is called ____. But not all lava is the same. Runny lava flows quickly and
forms the general slopes of shield volcanoes. Thick, sticky lava doesn’t flow as far and
tends to form the steeper slopes of composite volcanoes. Composite volcanoes can
erupt ________, throwing ash and lava at a speed of up to 200 miles per hour. These
eruptions sometimes blow away large chunks of the volcano itself. Some volcanoes, like
Hawaii’s Kilauea, form over hot spots in the Earth’s crust, where magma rises in the
middle of a tectonic plate. Kilauea is one of the most ______ volcanoes on the planet,
and it has erupted continuously since 1983. Because Kilauea is a shield volcano, this
constant eruption is a gentle one. Lava losing from Kilauea constantly hardens in the
new land, making _______ the only state that is still growing. Living near a volcano can
be hazardous, as the residents of Pompeii learnt in the year 79 AD, when Mount

Vesuvius erupted, spewing super heated ash, poisonous gas and rocks. This deadly
combination, called a pyroclastic flow, is far more dangerous than a lava flow.
_________ buried Pompeii, claiming the lives of 2000 people. Though volcanoes can be
deadly, they also provide benefits. Volcanoes created 80% of the Earth’s surface, as well
as much of the air we breathe today. Volcanoes create rich soil for farming, and many
countries harness their sole surface heat to create thermo energy. Both creators and
destroyers, volcanoes prove that beneath its calm surface, Earth remains a living planet,
and a _______ one.
