How Well Do You Know Arctic Climate?

An aurora borealis, also known as the Northern Lights, is a natural light display in the Arctic sky. It is caused by the interaction of electrically charged particles from the sun with the Earth's magnetic field, resulting in beautiful colorful phenomena.

Permafrost is a layer of permanently frozen ground that exists in the Arctic and some other cold regions. It consists of soil, rock, and debris that remains at or below freezing point for at least two consecutive years.

The Arctic tundra is known for its low biodiversity. The harsh conditions of the Arctic limit the number of plant and animal species that can survive in the region.

The largest Arctic predator is the polar bear. These majestic creatures are well-adapted to survive in the freezing conditions and rely on hunting seals for their primary food source.

The birch tree is a tree species adapted to survive in the Arctic. It is able to withstand the harsh climate, low temperatures, and short growing seasons of the region, making it an important component of the Arctic tundra ecosystem.

The main reason for the decline of Arctic sea ice is climate change. Increasing global temperatures are causing the ice to melt at an alarming rate, leading to various environmental consequences and habitat loss for Arctic species.

The albedo effect refers to the cooling effect of ice and snow in the Arctic. Ice and snow have high albedo, meaning they reflect a significant portion of incoming solar radiation back to space, helping to maintain lower temperatures in the region.

Russia has the longest coastline in the Arctic Ocean. The country's expansive northern territory borders the Arctic, making it the nation with the most extensive access to this unique and vulnerable ecosystem.

Solar radiation is the primary source of energy for the Arctic ecosystem. The long summer days in the region allow for significant absorption of sunlight, supporting the growth of plants and driving various ecological processes.

Methane is the main greenhouse gas emitted from the thawing permafrost. As permafrost melts, organic matter trapped within it decomposes and releases significant amounts of methane, which further contributes to global warming and climate change.
