The most active geothermal resources are usually found along major tectonic plate boundaries where most volcanoes are located. One of the most active geothermal areas in the world is called the Ring of Fire, which encircles the Pacific Ocean.
When magma comes near the earth's surface, it heats ground water trapped in porous rock or water running along fractured rock surfaces and faults. Hydrothermal features have two common ingredients: water (hydro) and heat (thermal).
Geologists use various methods to find geothermal reservoirs. Drilling a well and testing the temperature deep underground is the most reliable method for locating a geothermal reservoir.
Answer:
Secondary succession is a process in which a given area is disturbed, being re-colonized by other organisms following this process.
Explanation:
Secondary succession steps:
1- An area suffers a disturbance (e.g., fire, flood, earthquake, etc).
2-The process of disturbance destroys the food chain by removing primary producers (e.g., plants)
3- The vegetation grows back (i.e., first grasses and after higher trees). This process is known as recolonization
The secondary succession can regenerate an ecosystem in less than 50 years after disturbance. The first species re-established during secondary succession are the animals capable of living in disturbed habitats.
crystallization, metamorphism, and erosion and sedimentation
