01- Read the given information and answer the questions below:
Earthquake are the shaking and moving of the ground when energy is release in
waves. These waves are called seismic waves. These waves are similar to ocean waves
which move through water Most earthquakes are cause by the movement of large sections
of the earth crust called plates. The place where two plates meet is called a fault Faults
look like large cracks in the ground if the two plates move in different directions, they
build up energy at the fault line When enough energy builds up the stress on the fault
become too great and it ruptures. This releases the energy and the ground starts to shake
Earth quake can also be caused by other natural events such as landslides and
volcanoes manmade earthquakes happen because of nuclear testing and mining explosions
The first movement of an earthquake called the main shock is often followed by smaller
ground trembles called aftershocks These aftershocks are the plates settling into their new
position Aftershocka can continue for days after the main shock.
There are an estimated 500 000 earthquakes around the world each year Most are
se muld they are only recorded on scientific instruments Only about 100.000 can be felt by
humans of these only about nineteen, a year causes major damage Major earthquake in
populated areas can cause huge destructions, building collapse, roads and bridges buckle
and cracks and electrical and gas lines break and cause fires
If the earthquake happens in the ocean it makes a series of huge ocean waves
called a tsunami The tsunami travels until it finally reaches land where it causes large
flooding Scientists are searching for ways to predict earthquakes. While they cannot
predict an exact date of a future earthquake they have a better understanding of when
earthquakes are more likely to happen.
1. Define Earthquake..
2. Write any 2 causes of earthquake
3. Which waves are similar to ocean waves?
4. How many shocks are there? Name them accordingly.
5. Where do the two plates meet and explain how does the energy release?
6. List some destructions caused by major earthquakes.
7. Can scientist predict the exact date of earthquake?
8. Search any TWO verbs from the passage and write their second form
b)
d)
question answer
Answers
Answer:
1) The shaking and moving of the ground when energy is release in waves it is called as earthquake.
2) Landslides and mining explosions are the causes of earthquake.
3) Seismic waves are similar to ocean waves.
4) There are two types of shock, namely, main shock and after shock.
5) The place where two plates meet is called faults.if the two plates move in different directions, they build up energy at the fault line When enough energy builds up the stress on the fault become too great and it ruptures. This releases the energy.
6) Huge destructions, building collapse, roads and bridges buckle and cracks and electrical and gas lines break and cause a fire. This destruction is caused by major earthquakes.
7) Scientists cannot predict an exact date of earthquake.
8)
