English: How crater-depth is measured, using the side-view of a typical crater. Depth "A" measures from the surface to the bottom of the crater. Depth "B" measures from the mean height of the rim to the bottom of the crater.
A hydrologic model is a simplification of a real-world system (e.g., surface water, soil water, wetland, groundwater, estuary) that aids in understanding, predicting, and managing water resources. Both the flow and quality of water are commonly studied using hydrologic models.
Crater Lake in Oregon, USA. Lakes in calderas fill large craters formed by the collapse of a volcano during an eruption. Examples: Crater Lake, Oregon, United States; Heaven Lake, China/North Korea; Lake Toba, Sumatra, Indonesia; Soda Lakes in Nevada, USA. Lakes in maars fill small craters where an eruption deposited debris around a vent. Examples:
Crater lakes form as the created depression, within the crater rim, is filled by water. The water may come from precipitation, groundwater circulation (often hydrothermal fluids in the case of volcanic craters) or melted ice. Its level rises until an equilibrium is reached between the rates of incoming and outgoing water.
The depth of an impact crater in a solid planet or moon may be measured from the local surface to the bottom of the crater, or from the rim of the crater to the bottom. Crater depth diagram. The diagram above shows the full (side) view of a typical crater. Depth "A" measures from the surface to the bottom of the crater.
Oregon's Crater Lake is the deepest lake in America and has crystal-clear waters. But it didn’t used to be a lake at all. This gorgeous lake was once a mountain.
The diagram also shows how human water use impacts where water is stored and how it moves. [1] The water cycle (or hydrologic cycle or hydrological cycle) is a biogeochemical cycle that involves the continuous movement of water on, above and below the surface of the Earth. The mass of water on Earth remains fairly constant over time.
The Perseverance spacecraft landed on Mars in February 2021 and has been doing reconnaissance missions and looking for signs of life.
