The Canadian Shield is the landform region made from some of the oldest rocks on Earth. It consists primarily of ancient Precambrian granite and is characterized by its rugged terrain, exposed bedrock, and numerous lakes. This region covers a significant portion of eastern and central Canada and extends into parts of the northern United States. The rocks in the Canadian Shield are estimated to be over 4 billion years old.

What type of landform is Deccan?
Deccan is a large plateau region in India, characterized by its flat-topped hills and escarpments. It is primarily made up of basaltic rock and is one of the oldest landforms in the Indian subcontinent.
Which polar region contains the most land?
The Arctic region contains more land than the Antarctic region. The Arctic region is made up of the Arctic Ocean surrounded by various countries like Canada, Russia, and Greenland. In contrast, the Antarctic region is a continent covered by ice that is located at the South Pole.
How would the age of the oldest rocks on the continents compare with the age of the oldest rocks on the seafloor if the rock on the continents is continually formed but not removed?
The oldest rocks on the continents would be much older than the rocks on the sea floor because the rocks on the continents are not being removed unlike the rocks on the sea floor that are made by the mid-ocean ridge are being removed by deep ocean trenches. this prossess that is occuring on the sea floor is called sea floor spreading. evidence of this is the Pacific ocean shrinking and the Atlantic ocean growing.
How many types of rock are in the geoneedle?
The Geoneedle in Scotland is made up of three different types of rock: Lewisian gneiss, Moine schist, and Torridonian sandstone. These rocks represent some of the oldest formations in the region and provide a glimpse into the geological history of the area.
How would the age of the oldest rock on the continents compare with the age of the oldest rock on the seafloor?
The sea floor is young (the rocks are made at the mid oceanic ridges and spread out form there) while most of the continental rocks are older. This is because the continental crust floats on top of the oceanic crust and is therefore not recycled.
