CONTINENTS AND COUNTRIES

The planet we live on is the Earth. The Earth is round. If you look at the Earth from the space you will be able to see land, seas, oceans, continents and even countries. Sometimes you can see them through clouds.1 They look very beautiful when the sun rises or sets.

There are four oceans and six continents. The continents are: Europe and Asia, Africa, America, Australia, Antarctic. America consists of North America and South America. The continents are very large. Oceans and seas wash them and separate them from each other. There are usually many countries on the continents. For example, there are more than 40 countries in Africa, but there is only one country in Australia. It has got the same name as the continent. Australia is a very big country, but some countries are small. Iceland is a very small country. It is situated on the island in the north of Europe. Let’s name some countries from each continent: Russia, Great Britain, France, Germany, Spain, Italy are in Europe. China, India, Vietnam are in Asia. Canada and the United States are in America. Egypt is an African country.

The largest country in the world is Russia. The smallest country is the Vatican. All the countries have interesting people, places, animals and plants.

People of different nationalities live in these countries. They speak different languages. Each country has its national flag, anthem and its own traditions and customs.
