Introduction of the theme and aims

Teacher:

So, students, our earth is unique among other planets. But why?


Now, look at the slide. What can you see in the picture? Continents and oceans


So, the theme of our lesson is Continents and ocean basins. Today, at the lesson we’re going to learn new vocabulary on the theme, to learn the continents and ocean basins and to differentiate oceanic crust and continental crust.


Let’s read the names together because some of them are difficult to pronounce.

Repeat after me

Work with a map. Look at the map and name the continents and oceans.


Teacher: How many continents are there? Six. Can you name them? ( SS name the continents)

Teacher: How many oceans do you know? Four. Name them. (SS name the oceans)


Teacher:

The Earth's land is separated into large landmasses called continents.There are 6 continents: Eurasia, North America, South America, Africa, Australia, Antarctica.


An ocean is a body of saline ['seɪlaɪn] water that composes much of a planet's hydrosphere. Oceans occupy two-thirds of the planet's surface. The oceans of Earth are unique in our Solar System. No other planet in our Solar System has liquid water. There are 4 oceans.


Questions

Teacher: Let’s check your knowledge on the continents and oceans.

  1. What is the largest continent in the world? Eurasia

  2. What is the second largest continent? Africa

  6. What is the highest, driest, windiest, emptiest, coldest place on earth? Antarctica

  7. What continent was named after the explorer Americo Vespucci? North America

  8. Which is the largest ocean in the world? The Pacific Ocean


Consolidation

Teacher explains “Continental and Oceanic Crust”.


The Earth’s crust is divided into two types: the continental and the oceanic crust. The continental crust is found under land masses i.d. continents. The oceanic crust is found under the ocean floor. The continental crust is composed of three layers: they are the sedimentary, granitic and basaltic ones. The oceanic crust is made up of 2 layers: sedimentary and basaltic. There is no granitic layer.


To know more information about the continental and oceanic crust, I offer you to watch a video about Earth’s layers. But before we start let’s do some exercises.


Before watching exercises

SS are to match the English words and phrases to the Russian ones.

Text

The earth’s crust is an outermost solid layer of the Earth. It is composed of magmatic, metamorphic and sedimentary rocks with the thickness from 7 to 70-80 kilometers. The crust is divided into two types: the continental crust and the oceanic crust. The continental crust is 3.8 billion years old. The oceanic crust is much younger. Itisabout 200 millionyearsold.


The continental crust is the crust under which the continents are built and is 30-40 km thick. The continental crust is thicker in the areas of major mountain systems where the thickness can be 70 km. The oceanic crust is the crust under the oceans, and is only 5-7 km thick.


40 percent of the Earth's surface is currently covered with continental crust. The continental crust is composed of three layers: they are the sedimentary, granitic and basaltic ones. The main layer is made up of granite rock which is light in color and which rich in such constituents like silicon, aluminum, and oxygen.

The density of the continental crust is much less as compared to the oceanic crust. Ithasanapproximatedensityof2.7g/cm3.


The oceanic crust is found under the deep ocean basins. It consists of dark-colored rocks made up of basalt. The basaltic layer in oceans has an average thickness of not more than 5 -8 km. This rock is made up of silicon, oxygen, and magnesium. The oceanic crust is much thinner as compared to the continental crust.
The
 density of the oceanic crust is about 3.0 g/cm3. Thecontinentalcrusthasalowerdensity.


Exercise III. SS answer the questions.

  1. What is the earth’s crust? (The earth’s crust is an outermost solid layer of the Earth.)

  2. What rocks is the earth’s crust composed of? (It is composed of magmatic, metamorphic and sedimentary rocks)

  3. What types of the earth’s crust do you know? (The crust is divided into two types: the continental crust and the oceanic crust.)

  4. Is the continental crust younger than the oceanic one? (The oceanic crust is much younger.)

  5. Where is the oceanic crust situated? (The oceanic crust is found under the deep ocean basins.)

  6. What layers is the continental crust composed of? (It’s composed of the sedimentary, granitic and basaltic layers)

  7. What rocks does the oceanic crust consist of? (It’s composed of sedimentary and basaltic layers)

  8. Is the continental crust much thinner than the oceanic crust? (No, it isn’t. The oceanic crust is much thinner as compared to the continental crust.)


Reflection. Group work

Teacher: So, now there is a special task for each group. You can choose any card.


The 1st task is to draw the continental and the oceanic crust and mark out the main layers. And to tell us about them.


The 2nd task is to draw the geologic profile of the continental and the oceanic crust using the symbols below.


The 3rd task is to fill out the table.


Fill in the table.

Teacher:

To summarize all the information about the continental and oceanic crust I suggest you Venn diagram. You should find differences and similarities of these types of the crust.

Teacher:

Today you have done a great job. Every student was very active at the lesson, so there are no unsatisfactory marks. I’ll put excellent mark to the most active students especially to those who prepared presentations.


Our lesson is over! I hope it was useful for you. Thanks for your active participation. Good bye.

Home work

Retell the text and learn by heart new words and word expressions.

Resume of the lesson

You’ve done the great job today.

Your marks for the lesson are…
