What are two things that cause the population to grow?
# An increase in food. # Loss of competition. # Loss of predation # Increase survival of young # Better utilization of resources
What is one cause of a country population increase?
a higher birthrate then Death Rate.
What is the cause and effect if the population of deer in a forest increases and the population of wolves in a forest increases?
The increased deer population is the cause and the increased wolf population is the effect (more deer means more food for the wolves, which enables their population to increase).
Why the atmosphere is heated from below?
Because of the pressure in the center of the earth. Which also cause earthquakes. Edit: No. Most of the heat comes from the sun and is reflected back out.
What would be the most likely effect of an increase in the use of CFCs?
The effects of CFC's are very adverse. They could cause the all important ozone layer to be depleted.
What does a decrease in the height of the mercury column usually indicate on a barometer?
low pressure system and stormy weather
What are the difference between the mercury barometer and aneroid barometer?
A mercury barometer works by, measuring the height of a column of mercury in a sealed tube, supported by the atmospheric pressure.An aneroid barometer measures the amount of distortion of a sealed metal can, due to changes in atmospheric pressure. The equivalent column of mercury supported by a mercury barometer, can then be calibrated in mmHg by comparison.Both instruments do the same job and can be calibrated in Millibars or mmHg, or both.
What atmospheric conditions must occur to cause a barometer to rise?
To cause a barometer to rise, high pressure and sinking air must dominate the atmosphere. High pressure occurs when air is sinking and compressing, leading to clear skies and generally fair weather conditions. This sinking air prevents the formation of clouds and causes the barometric pressure to rise.
What can cause a vhange on air pressure?
One of the earliest forecasting tools was the use of atmospheric pressure. Soon, after the invention of the barometer, it was found that there were natural fluctuations in air pressure even if the barometer was kept at the same elevation. During times of stormy weather the barometric pressure would tend to be lower.
Does a increase in pressure cause an increase of reaction rate?
Yes
An aneroid barometer is different from a mercury barometer in that it?
An aneroid barometer, invented by the French 19th century engineer and inventor Lucien Vidie, uses a small, flexible metal box called an aneroid cell. This aneroid capsule (cell) is made from an alloy of beryllium and copper. The evacuated capsule (or usually more capsules) is prevented from collapsing by a strong spring. Small changes in external air pressure cause the cell to expand or contract. This expansion and contraction drives mechanical levers such that the tiny movements of the capsule are amplified and displayed on the face of the aneroid barometer.A mercury barometer has a glass tube of at least 84 cm in height, closed at one end, with an open mercury-filled reservoir at the base. The weight of the mercury creates a vacuum in the top of the tube. Mercury in the tube adjusts until the weight of the mercury column balances the atmospheric force exerted on the reservoir. High atmospheric pressure places more force on the reservoir, forcing mercury higher in the column. Low pressure allows the mercury to drop to a lower level in the column by lowering the force placed on the reservoir. Since higher temperature at the instrument will reduce the density of the mercury, the scale for reading the height of the mercury is adjusted to compensate for this effect.

Can constipation cause high blood pressure?
It doesn't cause high blood pressure. However, it can increase your blood pressure.
Why does a restriction cause a drop in pressure?
A restriction will increase pressure and decrease volume
Can a sudden drop in temperature cause you to be sick?
it can give you an awful headache cause of the changes in pressure and barometer. just take a wet wash cloth and put it over your eyes
Does increased parasympathetic activity cause blood pressure to increase?
no
Does fanning air brakes cause air pressure to increase?
No you lose air pressure .
