Monolith with bull, fox, and crane in low relief at Göbekli Tepe. The density of most stone is between 2 and 3 tons per cubic meter. Basalt weighs about 2.8 to 3.0 tons per cubic meter; granite averages about 2.75 metric tons per cubic meter; limestone, 2.7 metric tons per cubic meter; sandstone or marble, 2.5 tons per cubic meter.
The size of solid bodies does not include an object's atmosphere. For example, Titan looks bigger than Ganymede, but its solid body is smaller. For the giant planets , the "radius" is defined as the distance from the center at which the atmosphere reaches 1 bar of atmospheric pressure.
For a size comparison, a clay-sized particle is 1/1000 the size of a sand grain. This means a clay particle will travel 1000 times further at constant water velocity, thus requiring quieter conditions for settlement. [3] The formation of clay is well understood, and can come from soil, volcanic ash, and glaciation.
The following is a list of rock types recognized by geologists.There is no agreed number of specific types of rock. Any unique combination of chemical composition, mineralogy, grain size, texture, or other distinguishing characteristics can describe a rock type.
Rock varies greatly in strength, from quartzites having a tensile strength in excess of 300 MPa [27] to sedimentary rock so soft it can be crumbled with bare fingers (that is, it is friable). [28] (For comparison, structural steel has a tensile strength of around 350 MPa. [29])
“The impact ejected high-energy streams of rock that carved two canyons … in less than 10 minutes.” For comparison, it took 5 million to 6 million years for water to erode the landscape of ...
