A type of rock that forms directly from precipitates of hot water is called a <u>hydrothermal</u> rock
What is a hydrothermal rock?
- Hydrothermal essentially means “hot water.”
- Hydrothermal rocks are those rocks whose minerals crystallized from hot water or whose minerals have been altered by hot water passing through them.
- Thus, these rocks are distinct from metamorphic rocks, which are created by solid‐state mineral transformations.
- In fact, many hydrothermal rocks (such as those that form from hot springs and geysers or crystallize as veins in cracks in other rocks) actually build up in layers, much as sedimentary rocks do.
- Veins result when hot water moves through cracks in the bedrock of the crust.
- Various minerals are precipitated on the sides of the crack as the temperatures decrease.
- The shape and orientation of the minerals depends on the temperature, pressure, and rate of flow.
- When all the available space in the crack has been filled with mineral deposits, the crack is sealed and the vein is complete.

Answer:
Topography
Explanation:
The topography is a process of the study of the surface of the earth. It is related to the shape and features of the land. It is a field of science that is related to geo-science and planetary science and it gives information about the shape, feature of natural local history and culture. It represents the whole land-form on a map. It is the position of any of the features and generally, altitude, latitude, magnitude, etc, The study of topography was done specially for military tasks and geological survey.
