What is the main difference between alpine glaciers and continental glaciers?

Alpine glaciers are smaller in size compared to continental glaciers.

Alpine glaciers are only found in Antarctica and Greenland, while continental glaciers can be found on all continents.

Alpine glaciers form from snow layers pressing together, while continental glaciers are formed from ice.

Alpine glaciers are found in mountains, while continental glaciers spread out over large areas of land. (correct)

What is the distinguishing feature of sedimentary rocks?

They are made of sediment that gets compressed and hardens into rock. (correct)

They are formed when rocks are subjected to heat or pressure.

They are formed from cooling and crystallization of magma.

They are created from heat and pressure on their journey down to the core.
