1.
Antartica is the fourth largest continent
Correct Answer
B. False
Explanation
Antarctica is not the fourth largest continent. It is actually the fifth largest continent in terms of land area. The correct order of continents from largest to smallest is Asia, Africa, North America, South America, Antarctica, Europe, and Australia.
2.
Antarctica is surrounded by the South Pole
Correct Answer
A. True
Explanation
Antarctica is surrounded by the South Pole because the South Pole is located at the southernmost point on the Earth's surface, and Antarctica is the continent that is located around the South Pole. This means that the South Pole is essentially in the center of Antarctica, making it completely surrounded by the continent. Therefore, the statement "Antarctica is surrounded by the South Pole" is true.
3.
Antarctica is the second coldest place on earth
Correct Answer
B. False
Explanation
Antarctica is actually the coldest place on earth, not the second coldest. It is known for its extremely low temperatures, with the lowest ever recorded being -128.6 degrees Fahrenheit (-89.2 degrees Celsius). This freezing climate is due to its location at the South Pole, where it experiences long periods of darkness and receives little to no sunlight. The icy continent is covered in a thick ice sheet, which helps maintain its frigid temperatures. Therefore, the statement that Antarctica is the second coldest place on earth is incorrect.
4.
The only human settlements on Antartica are research stations
Correct Answer
A. True
Explanation
The statement is true because Antarctica is a continent dedicated to scientific research and environmental conservation. It is governed by the Antarctic Treaty System, which prohibits any commercial or industrial activities. Therefore, the only human presence on Antarctica is in the form of research stations established by various countries for scientific exploration and study of the unique ecosystem. These research stations provide accommodation, laboratories, and logistical support for scientists and researchers, making them the only human settlements on the continent.
5.
Several countries own land in Antarctica
Correct Answer

Explanation
The statement "Several countries own land in Antarctica" is false. Antarctica is governed by the Antarctic Treaty System, which prohibits any country from owning land in Antarctica. The treaty promotes scientific research and international cooperation, and ensures that Antarctica remains a demilitarized and peaceful continent. While several countries have territorial claims in Antarctica, these claims are suspended under the treaty and no country has sovereignty over any part of the continent.
6.
Winter in Antarctica is always light and the sea is thawed
Correct Answer
B. False
Explanation
The statement is false because winter in Antarctica is actually characterized by long periods of darkness, with the sun not rising above the horizon for several months. Additionally, the sea around Antarctica freezes during winter, forming a thick layer of ice. Therefore, the given statement is incorrect.
7.
Winter in antarctica occurs
Correct Answer
B. May - July
Explanation
Winter in Antarctica occurs from May to July. This is because Antarctica is located in the Southern Hemisphere, where the seasons are opposite to those in the Northern Hemisphere. During these months, the continent experiences the coldest temperatures and the longest nights. The extreme cold and darkness make it challenging for life to thrive in this harsh environment.
8.
A large body of salt water
Correct Answer
A. Sea
Explanation
The correct answer is "sea" because a sea is a large body of salt water that is partially enclosed by land. It is smaller than an ocean and usually connected to an ocean.
9.
A large body of salt water surrounding the continents
Correct Answer
B. Ocean
Explanation
An ocean is a large body of salt water surrounding the continents. It is a vast expanse of water that covers a significant portion of the Earth's surface. Oceans are deeper and more extensive than seas, and they play a crucial role in regulating the planet's climate and supporting diverse marine life. Icebergs, on the other hand, are large chunks of ice that float in the ocean but do not encompass it entirely. Therefore, the correct answer is ocean.
10.
A slow moving river of ice
Correct Answer
B. Glacier
Explanation
A glacier is defined as a sluggish, massive flow of ice, either resembling a slow-moving mass or a river of ice. The classification of glaciers is based on their location, with continental glaciers and valley glaciers being the two primary categories.
11.
A huge treeless artic plain where the subsoil is frozen
Correct Answer
C. Tundra
Explanation
The correct answer is tundra. Tundra refers to a vast, treeless arctic plain where the subsoil is permanently frozen. This environment is characterized by extremely cold temperatures, short growing seasons, and a layer of permafrost. The tundra is home to unique plant and animal species that have adapted to survive in these harsh conditions.
12.
A huge chunk of ice floating in the sea
Correct Answer
C. Iceberg
Explanation
An iceberg is a large piece of ice that has broken off from a glacier or an ice shelf and is floating in the sea. It is typically found in polar regions and can be massive in size. The given description of "a huge chunk of ice floating in the sea" perfectly matches the characteristics of an iceberg. Tundra and gulf are not related to the given description and do not fit the context. Therefore, the correct answer is iceberg.
13.
A piece of land that is almost surrounded by water or that sticks out into the sea
Correct Answer
C. Peninsula
Explanation
A peninsula is a piece of land that is almost surrounded by water or sticks out into the sea. It is connected to the mainland by a narrow strip of land, while being surrounded by water on three sides. This geographical feature is commonly found along coastlines and can vary in size. Examples of famous peninsulas include the Iberian Peninsula (Spain and Portugal) and the Korean Peninsula.
14.
One of the main land masses on earth
Correct Answer
A. Continent
Explanation
A continent is one of the main land masses on Earth. It is a large, continuous area of land that is surrounded by water. Continents are distinct from other landforms such as gulfs and peninsulas, as they are much larger in size and often consist of multiple countries or regions. They play a significant role in shaping the Earth's geography and are home to diverse ecosystems and human civilizations.
15.
An area of sea that is partially surrounded by land
Correct Answer
B. Gulf
Explanation
A gulf is a large area of sea that is partially surrounded by land. It is typically deeper and more enclosed than a bay, and can be formed by the movement of tectonic plates or erosion. A gulf can be found along a coastline and is often named after the surrounding land or a nearby city. In contrast, a continent refers to a large landmass, while a peninsula is a piece of land that is surrounded by water on three sides. Therefore, the correct answer for this question is gulf.
16.
What ocean does not surround Antartica?
Correct Answer
B. Arctic
Explanation
Antarctica is surrounded by the Southern Ocean, commonly delineated as stretching from the periphery of the continent, including its ice shelves, to the location of the 'polar front,' which acts as a boundary separating it from the adjacent Pacific, Indian, and South Atlantic Oceans.
17.
The north pole and south pole are located on land and water
Correct Answer
B. False
Explanation
The statement is false because the North Pole and South Pole are not located on land and water. They are actually located in the Arctic Ocean and the continent of Antarctica, respectively. The North Pole is covered by sea ice, while the South Pole is located on the landmass of Antarctica.
18.
Is the south pole locaated in
Correct Answer
A. East antarctica
Explanation
The South Pole is located in East Antarctica. This region is known for its vast ice sheet and extreme cold temperatures. East Antarctica is the largest and most stable part of the continent, making it an ideal location for the South Pole to be situated. West Antarctica, on the other hand, is characterized by more instability and a thinner ice sheet. Therefore, the correct answer is East Antarctica.
19.

Therefore, the correct answer is not clear and the question may be incomplete or not readable.
21.
Slow moving rivers are called icebergs
Correct Answer
B. False
Explanation
The statement is incorrect. Slow moving rivers are not called icebergs. Icebergs are large pieces of ice that have broken off from glaciers or ice shelves and are floating in the ocean. Slow moving rivers are simply referred to as slow moving rivers.
22.
Icebergs have many different shapes and sizes. The movement of wind and water carve them. As they melt they change shape
Correct Answer
A. True
Explanation
Icebergs are formed when chunks of ice break off from glaciers or ice shelves and float in the ocean. Due to their exposure to wind and water currents, icebergs can undergo various shapes and sizes. The movement of wind and water can erode and sculpt the ice, causing it to change its shape over time. Additionally, as icebergs melt, they gradually lose mass and may undergo further changes in shape. Therefore, the statement "icebergs have many different shapes and sizes. The movement of wind and water carve them. As they melt they change shape" is true.
23.
There are more nutrients in the antarctic ocean than in any other ocean
Correct Answer
A. True
Explanation
The given statement is true because the Antarctic Ocean is known for its high nutrient content. This is due to the upwelling of nutrient-rich waters from the deep ocean, which supports a diverse and productive ecosystem. The cold temperatures and limited sunlight in the Antarctic also contribute to the preservation of nutrients in the water. As a result, the Antarctic Ocean has a higher concentration of nutrients compared to other oceans, making the statement true.
24.
What animal can not be found in the antarctica
Correct Answer
E. Koala
Explanation
Koalas cannot be found in Antarctica because they are native to Australia. Koalas are arboreal marsupials that primarily inhabit eucalyptus forests and feed on eucalyptus leaves. Antarctica is a continent located in the southern hemisphere and is characterized by extremely cold temperatures and a lack of vegetation, which makes it an unsuitable habitat for koalas.
