Location is an important key that takes a part in increasing populations. For example, in ancient Mesopatamia, farmers planted crops in the fertile soil (which s in the location) and soon farmers did not have enough land to grow food for e increasing amount of populations. Climate might affect populations in a region because if the land is well and fertile (the weather and climate is mild) people can thrive. I hope this helps!
Answer:
Characteristics are listed below
Explanation:
An estuary is defined as a coastal water body that is partially enclosed and where freshwater from other natural water sources like river will mix with the salt water coming from the ocean.
It's characteristics are;
- It has a concentration of dissolved oxygen gas
- It has varying degree of salinity which varies depending on the area where the fresh water mixes with the salt water.
- It has sediment load.
-The salinity could also depend on the tidal and wind influences.
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.
I believe it is Sand. because when sand hardens it's like a type of case that conceals things like bones hope this helps and have a great day :-)
