Answer:
a. fumarole -- 1. a vent from which steam escapes
b. geyser -- 4. an eruption of hot water and steam
c. hot spring -- 2. ground water has come into contact with hot rocks and risen to the surface
d. travertine -- 3. massive deposits of calcium carbonate around a hot spring
Explanation:
- A fumarole is opening of the crust and has emitted streams and gases like the carbon dioxide, and the sulfur dioxide, and hydrogen chloride, and hydrogen sulfide.
- The streams are formed by the boiling of the superheated water and its pressure falls when it reaches the ground surface.
- A geyser is a spring that is characterized by the discharge of the water ejected turbulently and is accompanied by a stream and exists at a few places on earth.
- A hot spring is a hydrothermal vent that is made by the emergence of the geothermally heated groundwater that rises form the earth crust.
- A travertine is a terrestrial sedimentary rock that is formed by the precipitation of the carbonate materials form the solution to the ground surface and a geothermally heated ground spring.

Answer:
The continents have moved over time.
Explanation:
Fossils are one of the best indicators of Earth's history. They are great information about how organisms looked, lived, evolved, but also they show what was the climate like, the geography, and even Earth's processes. The fossils are actually used as one of the best evidence for the theory of plate tectonics.
The reason why fossils are so important for the theory of plate tectonics is that there are numerous species of organisms that have been discovered in different continents that have no connection at present whatsoever and are far away from each other. It is practically impossible for exactly the same organisms to evolve in different places, especially not in different environments. In multiple specimens of a single species are left in several different environments, if they survive, they will all evolve different characteristics, not remain the same. This proves that continents that now are not connected, in the past were actually merged together, but because of divergent plate boundaries have moved away from each other.
