What is the name of North America's shield?
The name of North America's geological shield is the Canadian Shield. It is a large area of exposed Precambrian rock that covers a significant portion of Canada and parts of the United States. It is one of the oldest geological formations on Earth.
Why is Precambrian history more difficult to study than more recent geological history?
Precambrian history is more difficult to study because the rocks from this era have undergone significant alteration and destruction over billions of years, making them harder to interpret. Also, the lack of well-preserved fossils in Precambrian rocks makes it challenging to reconstruct ancient environments and ecosystems accurately. Additionally, the vast timescale of the Precambrian era poses difficulties in accurately dating events and establishing a precise chronology of geological events.
What Geologic Era was the Mixedwood plains ecozone created in?
The Mixedwood Plains ecozone was formed during the Quaternary Period, which is part of the Cenozoic Era, around 12,000 years ago during the last ice age.
What covered the interior of north America from Texas to Alaska?
During the Last Glacial Maximum, an ice sheet covered most of North America from Texas to Alaska. This ice sheet was part of the Laurentide Ice Sheet, which extended over much of Canada and parts of the northern United States during the peak of the last ice age.
What part of the earth was formed during the Precambrian Era?
The majority of Earth's continental crust, including many mountains and rocks, was formed during the Precambrian Era. This era lasted from about 4.6 billion to 541 million years ago.
What was Canada like during the Korean war'?

What animal first appeared during the precambrian era?
As far as we know for the majority of the Precambrian super-eon the only life on earth was bacteria.At the very end of the Precambrian multicelled life evolved. Amonst them jellyfish, invertibrates, sponges and pretty much a prehistoric version of most sealife today. There is also very suggestive evidence for simple plant life in the form of green algae in the Precambrian.
What was Canada's position in the during the American Revolution?
Canada was actually part of Great Britain and was a hiding place for Loyalists (people who where loyal to Britain).
Is the Precambrian time the longest or shortest part of Earth's history?
The Precambrian time is the longest part of Earth's history, spanning from the formation of Earth around 4.6 billion years ago to about 541 million years ago. It makes up about 88% of Earth's history.
What countries took part in Operation Overlord during the Normandy invasion?
Canada, UK, USA.
Canada's role in land air and naval war?
During WW2 they were part of the British commonwealth.
Why are more fossils found in the paleozoic era than in the precambrian era?
Fossils are more abundant in the Paleozoic era compared to the Precambrian era because during the Paleozoic era, multicellular life forms became more diverse and complex, leading to a greater likelihood of fossilization. In the Precambrian era, life forms were simpler and less likely to leave behind fossilized remains due to limited mineralization processes and the absence of hard body parts.
