Mudstone on Mars: This photograph, taken by NASA*s Mars Rover Curiosity in 2015, shows sedimentary rocks of the Kimberley Formation in Gale Crater. The crater contains thick deposits of finely laminated mudstone that represent fine-grained sediments deposited in a standing body of water that persisted for a long period of time - long enough to allow sediments to accumulate to significant thickness.

Sand Grains on the Surface of Mars: The ancient environment of Mars had streams, shorelines, alluvial fans and other sedimentary environments where sand grains were deposited. Today, many areas on Mars are covered with sand dunes and other aeolian features. The planet also has lots of sandstone exposed in the walls of its many impact craters. The largest grain at the top of this image is about 2 millimeters in diameter. Photo by NASA*s Mars Curiosity Rover.

Volcanic Explosivity Index: The spheres in the illustration above represent the volume of erupted tephra for some of the most widely-known explosive volcanic eruptions. Although most people believe that Vesuvius (79 AD - the Pompeii eruption), Mount St. Helens (1980), and Mount Pinatubo (1991) were enormous, they are very small compared to ancient eruptions such as Wah Wah Springs, Toba, Yellowstone, or Long Valley Caldera.
