The correct answer is - (1) velocity of the river decreases.
When the velocity (the speed) of the river decreases, be it at the entry of a lake, sea, ocean, or meandering, passing through a valley with very little change in altitude, the sediment starts to get deposited. This is due to the decrease in force caused by the decrease in velocity, there is not enough force to push the sediments further so they start to deposit because the river is not able to drag them further on.
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.
Continentality is used to describe an inland climate that is remote from the moderating influences of large bodies of water.
<h3>What is the effect of continentality?</h3>
Continentality refers to a climatic effect that emerges because of the different range of temperature that exists at places lying in the interior of the continent away from the moderating influence of the sea and the places that are located near the continent.
Continentality causes water to warm more slowly than land when exposed to high amounts of solar radiation, to cool more slowly than land and to store more heat than land.
