Q:

How were the Arctic lowlands formed?

A:

The Arctic lowlands were formed by sheets of ice moving across the land, called glaciation. As the glaciers moved across the lowlands, they dug up sediment and gave the surface a rolling, corrugated look.

The Arctic lowlands were formed by the movement of glaciers across the surface 7,500 years ago, according to The Canadian Encyclopedia. The lowlands in the Arctic Archipelago were formed not only by glaciation, but by faulting in the rock, which also accounts for the channels between the islands. Although the glaciers have long disappeared from the Arctic lowlands, the land still remains frozen for most of the year, making farming impossible. However, the lowlands are formed of sedimentary rock, which is rich in coal, oil, natural gas and limestone.

The Arctic lowlands include the Arctic Archipelago and are located in northern Canada, lying roughly between the northern Innuitian region and the southern Canadian Shield. The Arctic Lowlands along with the Arctic Coastal Plains make up a fourth of Canada. The fresh water in the Arctic lowlands are covered with ice 10 months of the year, only free of ice in July and August. Despite the severe cold, polar bears, muskox and arctic fox thrive in the lowlands.

  • Q:

    What are the physical features of the arctic lowlands?

    A:

    The arctic lowlands consist of several barren low-lying islands with coastlines dominated by sheer, towering cliffs and frigid surrounding waters of the Atlantic that contain pieces of massive ice sheets. Together, the lowlands comprise the southwestern Arctic Archipelago. They vary in size and shape: some are small and unpopulated, while others, including Victoria Island, are much larger.

    How are bays formed?

    A:

    According to NationalGeographic.com, bays are formed through various ways, such as plate tectonics, overflowing of the ocean to a coastline and the slicing of a glacier through a bedrock. Bays are bodies of water partially surrounded by land, and they are typically less enclosed and smaller than a gulf.

    How was Uluru formed?

    A:

    Uluru began to form over 550 million years ago when sand, eroding from the Peterman Ranges, built up into thick deposits. Some 50 million years later, these deposits were compressed into sandstone by the weight of a sea that eventually disappeared. Within another 100 million years, geological events caused the sandstone to tilt almost 90 degrees, resulting in Uluru.

  • Q:

    How are islands formed?

    A:

    Islands form in several ways. The most common events that lead to island formation are volcanic activity and continental drift. Islands also form due to erosion, buildup of sediment and coral that grows enough to penetrate the surface of the water.
