Why is radiometric dating an example of absolute dating?
Geology and GeographyRadiometric dating. Most absolute dates for rocks are obtained with radiometric methods. These use radioactive minerals in rocks as geological clocks. The atoms of some chemical elements have different forms, called isotopes. Why is radiometric dating referred as absolute dating? Radiometric dating is referred to as absolute dating because it gives scientists a precise age

What is the difference between AU shaped valley and AV shaped valley?
GeologyGlacial erosion causes the formation of U-shaped valleys, whereas V-shaped valleys are the result of carving by the rivers through their course. U-shaped valley walls are straighter than V-shaped valleys due to the non-bending glacier’s movement. Glaciers do not get influenced easily by rock hardness as are rivers. How are U and V shaped valleys
