When an ice age ended the land once covered by ice was mostly?
It depends on the area. As the ice sheet moved backwards it melted and water flowed from underneath it producing an 'out wash plain'. In North American, these areas are seen as flat wide areas. The are also called the Great Plains. As they continued to move back and melt more, very large ice berg shaped pieces would break off the face (calving). The large ice pieces would remain behind. The sheet would continue to move back and water containing sand, gravel and boulders would flow around those ice bergs. Many of these ice bergs would be so large that they formed large deep lakes surrounded by moraines. These moraine would be filled with that gravel, rocks and sand. The lakes are called kettles as they remind people of very large cooking pots. This area is very hilly with many lakes (large and small). There are still places where the moraines are removed and the sand and gravel is sold for building material like cement. Further back, the mountains that were once there had been ground down and that material became the sand, gravel and rocks. The mountains themselves were not like the Alps or the Rockies any more but what we call the Appalachians.
Is sand an element mixture or compound?
Sand is a mixture, not a compound, as it is made up of different elements such as silicon, oxygen, and occasionally other minerals. These elements are not chemically bonded together in a specific ratio to form a new substance.
Why does soil retains water better than sand?
Soil retains water better than sand because it has smaller particles with more surface area to trap and hold onto water molecules. Additionally, soil contains organic matter that can act like a sponge, absorbing and storing water. Sand, on the other hand, has larger particles with less surface area and does not have the same capacity to hold water.
How many grains of sand in the Sahara?
It is estimated that there are around 2.5 billion grains of sand in a cubic meter. The Sahara Desert covers an area of about 9.2 million square kilometers, so calculating the total number of grains of sand in the Sahara would require very complex math and assumptions. it is practically impossible to accurately count the total number of grains of sand in the Sahara Desert.
