Salinity and density share a positive relationship. As density increases, the amount of salts in the water—also known as salinity, increases. Various events can contribute to change in the density of seawater. Salinity can decrease from the melting of polar ice or increase from the freezing of polar ice.

Answer:
Average annual temperature in US cities would range between 50-70 degrees Fahrenheit
Explanation:
There are several factors that can influence the temperature of city in general. Higher altitude has a lower temperature because it has less air density and absorbs less sunlight. The city latitude coordinate also determines how much sunlight they will get. The closer the city to the equator, the more sunlight they can get.
Distance to the sea will influence the rate of rainfall and also influence temperature. Ocean currents can move hot water from other regions too.
Answer:
At 0 years, an event took place which is known as metamorphosis of igneous rock i.e., formation of igneous rocks from melted magma.
Strontium-90 is a radioactive element which undergoes beta decay to form yttrium-90. It has a half life of approximately 28 years and decay energy of 0.546 MeV. This radioactivity is used by geologist to estimate the age of the rock, fossils, meteorites etc. Other radioactive elements used by the geologists are carbon-40, potassium-40 etc.
Radiometric clock is set when the rock was formed in the past i.e., the moment when an ingenious rock was solidified from molten magma.
By definition, a chaparral ecosystem is mostly located in the south of the United States wherein it mainly comprises the mountain ranges of Sierra Nevada. In addition to that, biotic characteristics of these chaparrals include having abiotic factos such as wet winters and dry summers that sometimes cause wildfires.
