- decreases as altitude increases
- results from a column of air pushing on an area
- decreases due to fewer air particles pushing down
Pressure is the force exerted, by a substance, per unit area.
Explanation:
Pressure is given by the formulae;
P = F/ A
Whereby;
P = pressure
F = Force
A = area
Remember that ..
F = Ma
Whereby;
F = Force
M = mass
a = acceleration
Therefore pressure can be given as;
P = Ma / A
The mass of the above column of a substance multiplied by the acceleration due to gravity = pressure exerted by the substance.

Answer:
Azurite and Magnesite react with hydrochloric acid.
Explanation:
These 2 rocks contain the carbonate mineral calcite dolomite. Carbonate minerals are unstable in contact with hydrochloric acid. When acid begins to effervesce (fizz) on a specimen, a reaction takes place and bubbles of carbon dioxide evolve, thus indicating the presence of minerals like calcite dolomite.
Hope my answer is correct and helpful :)
Based on a ruler in centimeters, with ten divisions between each centimer mark, you will have marks at every 0.1 cm.
Then, the measure of the length of a metal rod should have 1 decimal place.
That decimal place means mlimiters, given that 1 mm = 0.1 cm.
Answer: 1 decimal place
The qualitative-quantitavtive debate can trigger an intense debate. To say that one or the other approach is better is a trivializing of a far more complex topic than a dichotomous choice. ... Qualitative data typically consists of words while quantitative data consists of numbers.
1. Deforestation = the burning of fossil fuels to make energy
2. Combustio = the logging of trees, which removes producers from the carbon cycle
3. Circulation= the process which brings up nutrients from deep ocean
4. Weathering= the wearing down of rocks over time.
5. Calcium carbonate= the primary component to mollusk shells and coral skeletons
I hope this helped.
