What else can I help you with?
Two most abundant salts in seawater?
Sodium chloride, potassium chloride, magnesium chloride
What are two sources of oxygen in seawater at the surface?
Two sources of oxygen in seawater at the surface include atmospheric exchange, where oxygen from the air dissolves into the water, and photosynthesis by marine plants and phytoplankton, which produce oxygen as a byproduct.
What two salts are found in ocean salt water?
The most important is sodium chloride; other salts are magnesium, potassium, calcium chlorides and of course many minor salts.
What are two major sources of the elements in seawater?
These elements are transported by rivers to the sea. Another source is the volcanic activity.
Locate the two different types of source and destination?
The two different types of source are primary and secondary sources. Primary sources provide first-hand information, like original research or documents. Secondary sources analyze or interpret primary sources and provide commentary or analysis.
What are two primary sources for the materials that comprise the dissolved components in seawater?
The two primary sources for dissolved components in seawater are weathering of rocks on land, which releases minerals into rivers and eventually the ocean, and gases released by volcanic activity. These sources contribute ions like sodium, chloride, calcium, and magnesium to seawater.
Two most abundant salts in seawater?
Sodium chloride, potassium chloride, magnesium chloride
What two most abundant components dissolve in seawater?
Chlorides salts of Na, Mg, Ca.
What two types of sources that historians have?
The two different sources are primary and secondary sources
What are two sources of oxygen in seawater at the surface?
Two sources of oxygen in seawater at the surface include atmospheric exchange, where oxygen from the air dissolves into the water, and photosynthesis by marine plants and phytoplankton, which produce oxygen as a byproduct.
Run-off is high in nitrogen salts and mineral salts what are two possible sources of these mineral salts?
The cause is the irrational use of fertilizers.
What are the two sources that historians use?
primary sources and secondary sources.
What are the two main sources of salt in seawater?
1. The most important part of the sodium and chlorine are dissolved from the earth salts and transported by rivers in seas/oceans.2. A small part of chlorine is originated from the eruptions of submarine volcanoes
What are two natural processes that can increase the salinity of seawater?
Two processes are: >regular dissolving of mineral salts from the surroundings >more and more animals decafcdsafying in the sea.ghgd
What are the two primary sources for the materials that comprise the dissolved components in seawater?
Chemical weathering and out gassing
What are the 2 classifications of historical sources?
The two classifications of historical sources are primary sources and secondary sources. Primary sources are original, first-hand accounts of an event or topic, while secondary sources are interpretations or analyses of primary sources created by someone not directly involved in the event.
What are two sources of data?
Simple, Primary and Secondary Data
