Glacier grooves are an example of climate change evidence because?

• glacial grooves are found in Antarctica today and it is cold

• glacial grooves are found in the warm areas today, so it means that continent used to be near the poles

• glacial grooves are found in the cold today and it is closer to the poles

• glacial grooves are found in the warm areas because there was an ice age and continents were never together
