Answer:
Oceanic crust is created as magma rises to fill the gap between diverging tectonic plates and is consumed in subduction zones. It is geologically young, with a mean age of 60 Ma, and is thin, averaging 6.5 km in thickness. Oceanic crust consists almost exclusively of extrusive basalt and its intrusive equivalents.

Answer:
Physical properties of mercury are described here.
Explanation:
Mercury is a metal. Mercury is the only metal which is liquid at room temperature. Mercury is shiny silver in liquid form. It has a melting point of -38.9 degree Celsius and a boiling point of 356.7 degree Celsius. The symbol of mercury is Hg and it has an atomic number, 80 and atomic weight of 200.59. Mercury is a poor conductor of heat and good conductor of electricity. Mercury is considered a heavy metal.
In this question, its liquid form, and the volume of the mercury grows as temperature rises, are the examples of physical properties of the mercury.
Answer:
A biome is an enormous ecosystem, spreading over a broad geographic range.
Explanation:
Biomes are classified here in such a form as to get into account their corresponding ranges and similar weather. All climate zones, though, come into one of three essential classifications: tropical and subtropical, temperate, and polar and subpolar.
The first of specific categories is a term covering the area along the equator, spreading north and south by approximately 30 degrees in either direction. In North U.S, this would involve southerly Florida, Texas, and Louisiana. Temperate areas spread from about 30 to 60 degrees on each side of the equator, thus leading in most of America. Ultimately, subpolar and polar regions lie among 60 degrees and the poles, which occur at 90 degrees.
