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:
Rural dilution, a term originally used in the UK in the 1950s, refers to change in the social composition of rural populations: those elements engaged in primary production (and its necessary servicing) are thinned out by agricultural restructuring and labor shedding, while at the same time in-migration of new elements (retirement, long-distance commuting, lifestyle migration) is occurring. The extent to which such dilution occurs is influenced by a number of factors, including distance in travel time from the nearest metropolitan or other large city, location with respect to the coast/perceived environmental amenity, and rural population density. This paper explores changes in traditional rural communities in Southern Yorke Peninsula, South Australia, which lie 2½-3 hours' drive from Adelaide and have been subject to substantial rural dilution. Drawing on two detailed surveys of the strictly rural (dispersed) population of the region carried out in 1984 and replicated in 2000, some important social impacts of the recent migration flows are identified, including changes in perceived community identity and allegiance, shopping and business patterns, and the very recent impact of the uptake of electronic communication innovations. The paper concludes with an assessment of the extent to which the trends identified are likely to continue, and mold future communities in similar distance and amenity situations over the next 10-20 years, changing the nature of rurality in Australia.
