If a column of land is left behind by being eroded by waves its called?

If a column of land is left behind by being eroded by waves, it is called a sea stack. Sea stacks are formed when softer rock is eroded away, leaving a harder rock structure standing in the sea.


Why do different rocks weather at different rates?

Depending on the minerals in their composition, some rocks are harder than others. Rocks that contain minerals with higher ratings on the Mohs scale are harder, and would erode more slowly than other rocks.


Which element group is made up of shiny solids that are harder than alkali metals?

The group you're referring to is the group of alkaline earth metals. They are shiny solids that are harder than alkali metals. Examples include calcium, magnesium, and barium.


What is a coins texture?

a coins texture is different because it is much harder and mostly made out of copper and metal.


What is hplc column volume?

Since an HPLC column is a cylinder, the simplest estimate for the column volume is the equation V=L*pi*r2, where L = length of column (typically 50-250 mm, or 5-25 cm), and r=radius of the column, where typical internal diameters of HPLC columns are 2.1 mm, 3 mm, 4 mm, and 4.6 mm. For example, suppose you have a column that is 25 cm long by 4.6 mm internal diameter (ID). Since the ID is in mm, you first convert to cm, then divide by 2 to get 0.23 cm radius. The column volume equation then is: V = 25 * pi * (0.23)2 = 25 * pi * 0.0529 = 1.3225 * pi = 4.15 cm3 From there, you can convert cm3 to mL directly, so your column has a volume of 4.15 mL. However, you must also allow for the relative porosity of the packing material in your column, which is harder to measure. Typically, an unretained analyte will be injected through the column at a known flow rate, and the time it takes for the analyte to exit the column is used to determine a better approximation of column volume. In the case of using an unretained analyte (which in reversed-phase HPLC, the analyte might be Uracil), using the same 25 cm by 4.6 mm column above and a 1 mL/min flow rate, suppose the analyte elutes from the column at 3.2 minutes. The column volume would then be 3.2 minutes * 1.0 mL/min = 3.2 mL, which does not agree with the calculated column volume. This is due to the fact that the particles in the column take up some of the volume of the column, so the total column volume is reduced by the amount of space they take up.

When to use choke tubes?

You use the choke tube which is appropriate to the use of the shotgun. Choke tubes are short sections of tube which screws into the muzzle end of the shotgun barrel. Different tubes hve different amounts of constriction (full, modified, improved, cylinder bore, etc). The tighter the constriction, the more the shot column is kept together and thus the more dense the shot column. This keeps the column together longer as it flies down range and thus will put more pellets into the target. Tighter shot column also means that the pattern doesn't spread out as much and thus it's harder to hit a given target.

What is the hardest element in the world iron or diamonds?

Diamonds are harder than iron. Diamonds are the hardest naturally occurring substance known, scoring a 10 on the Mohs scale of hardness, while iron is relatively soft and malleable, with a Mohs hardness of around 4.


What is water column pressure?

Water column pressure is the measure of pressure exerted by a vertical column of water in a particular area. It is commonly used in hydrology and oceanography to describe the pressure at a given depth in a body of water. This pressure increases with depth due to the weight of the water above pushing down.
