Natural cracks in the rock that form due to the exhumation of deeply buried rock are called salt wedges.
Answer: Option 1
<u>Explanation:
</u>
The process of exhumation in the discipline of Geography refers to digging up of a buried rock due to natural forces applied on the surface under which the rock is buried. At a salt wedge, a river flowing with a great velocity meets the ocean where the ocean is comparatively calm.
The fast-flowing river water acts as a digging force and carries out the process of exhumation of the rocks at the wedge. The same fast-flowing water creates cracks in the exhumed rocks.
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.
The fossil range can simply be defined as the time period in which an organism has existed, thus left fossil traces of its existence. The fossil range can be very short, medium, or long, thus usually there are limitations before certain type of organism evolves into another species, thus eliminating the ancestral organism from the fossil records. On the other hand, there are organisms that have incredibly big fossil ranges of several hundred million years, and since they emerged, they have remained almost unchanged. Those kind of fossil ranges are very rare though, and they don't represent the general picture. Most of the fossil ranges are between several thousand years and several million years, as that is usually how much a species exists, ending its reign, be it because of competition, changes in the environment, or big natural disaster.
