Teacher:
You have done a great job. But there were some mistakes in your speech.
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.
What is the largest continent in the world? Eurasia
What is the second largest continent? Africa
What oceans is North America surrounded by? (the Pacific Ocean, the Artic Ocean and the Atlantic Ocean)
What is the largest desert in the world and where is it situated? The Sahara in Africa
What is the largest island and the smallest continent in the world? Australia
What is the highest, driest, windiest, emptiest, coldest place on earth? Antarctica
What continent was named after the explorer Americo Vespucci? North America
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.

Exercise III. SS answer the questions.
What is the earth’s crust? (The earth’s crust is an outermost solid layer of the Earth.)
What rocks is the earth’s crust composed of? (It is composed of magmatic, metamorphic and sedimentary rocks)
What types of the earth’s crust do you know? (The crust is divided into two types: the continental crust and the oceanic crust.)
Is the continental crust younger than the oceanic one? (The oceanic crust is much younger.)
Where is the oceanic crust situated? (The oceanic crust is found under the deep ocean basins.)
What layers is the continental crust composed of? (It’s composed of the sedimentary, granitic and basaltic layers)
What rocks does the oceanic crust consist of? (It’s composed of sedimentary and basaltic layers)
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.
Continental crust Oceanic crust
Age 3.8 billion years old About 200 million years old
Composition Sedimentary, granitic and basaltic rocks Sedimentary and basaltic rocks
Thickness 5 – 8 km 30-40 to 70 km
Density 2.7 g/cm3 3.0 g/cm3
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.
