KUTYÁK

A kutyák háziasítása során különféle viselkedési és külső jegyek alakultak ki, amelyeket kísérletek is vizsgáltak. A híres Beljajev-kísérlet során rókákkal végeztek szelekciós kísérleteket, ahol az emberrel barátságosabb egyedeket tenyésztették tovább, így néhány generáció után egyre több, kutyákra jellemző tulajdonság jelent meg.

KUTYÁK

KUTYÁK

The first division between continents was made by ancient Greek navigators, who named them 'landmass, terra firma'.

Generally classified by convention rather than any strict criteria, nowadays seven regions are regarded as continents from a geopolitical point of view.

Antarctica

Antarctica is not only the coldest place on Earth but also the highest, driest, windiest and emptiest, completely covered with ice.

75% of the world's ice and 70% of the Earth's fresh water is located here.

Summer months of December to February give 24 hours of light, while the winter months of late March to late September are pitch dark the whole day.

There are no permanent inhabitants, except for scientists maintaining research stations in Antarctica.

There is plenty of animal life in Antarctica. It is a continent of extreme conditions but a range of well-adapted animals thrive here at various times of the year.

Name at least 5 of these animals.

Kutya háziasítása

North America has five time zones and it is the only continent with every type of climate.

North America was named after the explorer Amerigo Vespucci and is also known as the 'New World'.

The world's largest sugar exporter among the seven continents - Cuba - also called the 'sugar bowl of the world' is located here.

The specialty of some animals is they are found only in a particular region and nowhere else in the world. North America is home to many of such amazing animals.

Name at least 6.

3rd Largest River

Native Americans have lived along this river and its tributaries for thousands of years. Most were hunter-gatherers, but some formed agricultural societies.

Formed from thick layers of the river's silt deposits, this river's embayment is one of the most fertile regions of the United States; steamboats were widely used in the 19th and early 20th centuries to ship agricultural and industrial goods.

Name this river.

Largest Lake

The world's largest freshwater lake by surface area and the third-largest freshwater lake by volume can be found here. It provides a route for the transportation of iron ore, as well as grain and other mined and manufactured materials.

Large cargo vessels called lake freighters, as well as smaller ocean-going freighters, transport these commodities across this lake.
