What is a calcareous skeleton?
Its when a sea animal forms a skeleton from calcium carbonate (CaCO3). Calcium carbonate is dissolved in seawater, but less soluable at higher temperatures. The majority of animals with calcareous skeletons, such as corals, are found in the tropics where it takes less energy to get it out of the seawater
What are two kinds of solid structures made by marine animals from minerals they extract from seawater?
Two kinds of solid structures made by marine animals from minerals they extract from seawater are coral reefs, formed by coral polyps extracting calcium carbonate to build their intricate structures, and mollusk shells, like those of clams and oysters, made from calcium carbonate as well.
Which is more expensive sodium chloride or calcium chloride?
Calcium chloride is generally more expensive than sodium chloride. This is because calcium chloride is less abundant and requires more complex extraction processes compared to sodium chloride, which is commonly found in salt deposits and seawater. Additionally, calcium chloride is often used in industrial applications that command a higher price.
Which process most likely formed a layer of the sedimentary rock gypsum?
precipitation from seawater
What are 2 main factors that influence density if seawater?
Temperature and salinity are the two main factors that influence the density of seawater. Colder seawater is denser than warmer seawater, while seawater with higher salinity is denser than seawater with lower salinity.
When you mix calcium in seawater with carbon dioxide what is the new substance that formed?
The calcium carbonate is formed.
Which type of salt crystallizes from sea water first calcium sulfate or sodium chloride?
Sodium chloride (table salt) typically crystallizes first from seawater because it is more soluble and abundant in seawater compared to calcium sulfate. Calcium sulfate (gypsum) is less soluble and usually precipitates later when the seawater evaporates further.
What element can be extracted from seawater?
Sodium chloride (salt) is the most commonly extracted element from seawater. Other elements that can be extracted include magnesium, calcium, and potassium.
Why do polyps extract calcium from seawater?
Polyps extract calcium from seawater to build their calcium carbonate skeletons, which provide structural support and protection. This process is essential for the growth and maintenance of coral reefs, which are vital ecosystems in marine environments. The calcium carbonate structure also helps in the overall carbon cycling within the ocean. Additionally, extracting calcium contributes to the polyps' ability to thrive in various marine environments by enhancing their resilience against environmental changes.
What are the six ions in seawater?
The four MAIN IONS in seawater in descending order of abundance are: CI: Chloride Na: Sodium SO4: Sulfate Mg: magnesium Found in Leckie-Yuretich: Investigating the Ocean, Page 114, Seawater Salinity: The salt of the Ocean
How is calcium found in nature?
Calcium is found in nature primarily in the form of compounds such as calcium carbonate (in limestone and marble), calcium sulfate (in gypsum), and calcium phosphate (in bones and teeth). It can also be found in various minerals and in seawater.
Is seawater a solution?
Yes, seawater is a solution made up of several elements and compounds dissolved in water, such as salt (sodium chloride), magnesium, and calcium. It is considered a homogeneous mixture.
In sea water which salt is more sodium chloride or calcium?
In seawater, sodium chloride (table salt) is the most abundant salt present, accounting for approximately 85% of the total dissolved salts. Calcium salts are less abundant compared to sodium chloride in seawater.
What are sea salts?
The most important salt in the seawater is sodium chloride; also exist magnesium, calcium and potassium chloride.
