1.
Which one of the following does NOT describe the tundra?
Correct Answer
D. Has spruce trees
Explanation
The tundra is a biome characterized by extremely cold temperatures, permafrost, and a lack of trees. It is a vast, treeless landscape dominated by low-lying vegetation such as grasses, mosses, and lichens. Spruce trees, on the other hand, are commonly found in boreal forests, which are different from tundra ecosystems. Therefore, the statement "has spruce trees" does not describe the tundra.
2.
Which one of the following animals lives in the tundra?
Correct Answer
C. Lemming
Explanation
The correct answer is lemming. Lemmings are small rodents that are well adapted to live in the tundra, which is a cold and treeless biome found in the Arctic regions. They have thick fur and short legs, allowing them to navigate through the snowy terrain. Lemmings are herbivorous and feed on grasses, mosses, and other plants that are available in their harsh environment. They play a crucial role in the tundra ecosystem as a source of food for predators like birds of prey, foxes, and wolves.
3.
Which plant below does NOT grow in the tundra?
Correct Answer
A. Maple tree
Explanation
The maple tree does not grow in the tundra. The tundra is a cold and harsh environment with low temperatures and a short growing season, which is not suitable for the growth of trees like the maple tree. Lichen, moss, and grass are commonly found in the tundra as they are adapted to survive in such extreme conditions.
4.
Winter weather in the tundra can last up to how long?
Correct Answer
D. 9 months
Explanation
Winter weather in the tundra can last up to 9 months. The tundra is a cold and harsh biome characterized by extremely low temperatures and frozen ground. Due to its high latitude and proximity to the poles, the tundra experiences long and severe winters. These winters typically last for a significant portion of the year, with freezing temperatures and snowfall persisting for up to 9 months. The extended duration of winter in the tundra is a result of its unique climate and geographical location.
5.
The type of biome a region has is determined by the
Correct Answer
B. Climate
Explanation
The type of biome a region has is determined by the climate. Climate refers to the long-term weather patterns in a particular region, including factors such as temperature, precipitation, and humidity. These climatic conditions directly influence the types of plants and animals that can thrive in a specific area, which in turn determines the biome. For example, a hot and dry climate may result in a desert biome, while a cold and snowy climate may lead to a tundra biome. Therefore, climate plays a crucial role in shaping the characteristics and biodiversity of a biome.
6.
Which one of the following indicators is NOT part of the climate?
Correct Answer
D. Type of plants and animals
Explanation
Plants and animals are not indicators of climate, but rather they are influenced by climate. Climate is determined by factors such as annual precipitation, average temperature, and average wind patterns. These factors directly affect the climate of a region, whereas the type of plants and animals present in an area are a result of the climate conditions. Therefore, type of plants and animals is not considered as an indicator of climate.
7.
The tundra is sometimes called a cold desert because of it________
Correct Answer
A. Is cold and dry
Explanation
The tundra is sometimes called a cold desert because it is characterized by extremely low temperatures and a lack of precipitation. The cold climate and the absence of moisture make it similar to a desert, where dryness is a defining feature.
8.
Which animal below does NOT live in the tundra?
Correct Answer
C. Green tundra toad
Explanation
The green tundra toad does not live in the tundra. This can be inferred from the fact that the other three options, polar bear, arctic fox, and ducks and geese, are all known to inhabit the tundra. The green tundra toad is the only option that is not commonly associated with tundra habitats.
9.
It is possible to find a tundra climate on the equator.
Correct Answer
A. True, on mountain peaks
Explanation
Tundra climate is characterized by extremely cold temperatures and a short growing season. It is typically found in high latitudes, such as in the Arctic and Antarctic regions. However, it is also possible to find tundra climate on mountain peaks, even near the equator. This is because as elevation increases, temperatures drop, and the conditions can become suitable for tundra vegetation to thrive. Therefore, it is true that tundra climate can be found on mountain peaks, even if they are located near the equator.
10.
The tundra has permafrost, which means the soil is ...
Correct Answer
A. Frozen all the time
Explanation
The tundra has permafrost, which means that the soil is frozen all the time. This frozen condition of the soil inhibits the growth of plants and makes it difficult for them to establish roots. The permafrost layer also prevents water drainage, resulting in the formation of wetlands and marshy areas. This frozen state of the soil is a defining characteristic of the tundra biome.
11.
Where would you NOT find the tundra?
Correct Answer
D. In northern Indiana
Explanation
The tundra biome is characterized by extremely cold temperatures, low-growing vegetation, and permafrost. It is found in regions with high latitudes, such as northern Canada and northern Alaska, where the climate is cold and harsh. Tundra is also found on mountain peaks, as the high elevation creates similar conditions to the Arctic tundra. However, in northern Indiana, the climate is not cold enough to support tundra conditions, and therefore it is not found there.
