Why were so few dinosaurs found in Antarctica?
The reason that so few dinosaurs have been found in Antarctica is because it is almost impossible to dig for fossils on most of Antarctica. First, most if it is underneath a mile of ice. Secondly, because Antarctica is so harsh, few paleontologists go to dig even in the areas of rock that are exposed. To me, for those reasons, it's surprising that any dinosaurs have been found in Antarctica.
What do you called large chunks of bare rocks that travel around the sun?
Large chunks of bare rock that travel around the sun are called asteroids. Most asteroids are found in the asteroid belt between Mars and Jupiter, but they can also be found throughout the solar system. They vary in size and shape and are remnants from the early solar system that never coalesced into planets.
Where would you find glacial grooves in Antarctica?
Glacial grooves in Antarctica can be found on exposed rock surfaces, typically on nunataks or other high points where glaciers have flowed over the rock and carved out grooves with their abrasive action.
What percent of Antarctica isn't covered in ice?
Approximately 0.32% of Antarctica is not covered in ice, primarily made up of rock outcrops, mountain peaks, and small patches of bare ground. The vast majority of Antarctica is covered by ice, with some areas exceeding 2 miles thick.
What rocks found in the mantel?
The igneos rock is the most usual rock to form.

Is there a land under Antarctica?
Antarctica is a continent, so yes: under its ice sheet, there is land.
Where is most of the exposed rock in Antarctica?
You can see exposed rock in the nunataks -- where the mountain peaks poke out from the glaciers, and on the beach when it is not covered by ice.
Is Antarctica always covered in snow?
Antarctica is covered -- 98% -- by an ice sheet, not snow. You can find snow sometimes on the Antarctic Peninsula. The beaches are ice-free, as are the nunataks -- the mountain tops that poke above the ice sheet.
Where would you find glacial grooves in Antarctica?
Glacial grooves in Antarctica can be found on exposed rock surfaces, typically on nunataks or other high points where glaciers have flowed over the rock and carved out grooves with their abrasive action.
Fossil are found mainly in what kind of rock?
