On Earth, the air becomes less dense and loses pressure as it rises in height. There is a bad correlation between the two variables.
<h3>What is atmosphere?</h3>
The layers of gases that envelop a planet or other celestial body are its atmosphere. About 78% of the gases in the Earth's atmosphere are nitrogen, 21% are oxygen, and 1% are other gases.
<h3>What is air pressure?</h3>
Everything you touch is pressed upon by the weighty air that surrounds you. This pressure is referred to as air pressure or atmospheric pressure. It is the force that the air above a surface applies to it while gravity pulls the surface toward Earth. A barometer is frequently used to measure atmospheric pressure.
<h3>What is altitude?</h3>
Height above sea level is how altitude is defined. Air pressure and height are two different but related ideas. In fact, they are so closely related that many airplane altimeters base their altitude calculations on air pressure. And one can also do the opposite; mountain climbers can determine whether they need to bring an oxygen supply by forecasting the air pressure on a mountaintop with a known elevation.

All ik is that gold is a rare earth metal that dos not conduct electricity
Answer:
Displacement = 70 m towards east
Explanation:
Displacement is the shortest distance between the two points.
Let us say that he starts at the point O and travels in a path ABC.
If we join the initial and final point of the path travelled by him, it will give the displacement of the man.
Distance from O to A = 40 m
Distance from A to B = 70 m
Distance from B to C = 40 m
Distance from O to A = Distance from B to C
We want the displacement which is distance between the points O and C
In rectangle opposite sides are equal. Hence Distance from O to C = Distance from A to B
Displacement = Distance from A to B

Answer:
Float
Explanation:
It is given that,
The density of water is 1 g/mL
The density of a rock is 0.87 g/mL
It can be seen that the density of water is more than that of rock. The density of an object is calculated from its mass and volume.
If the density of liquid in which it is placed, is more that that of the object, it will float at the top.
Hence, in this case the rock will float.
Complete question is:
It's is difficult to walk on a wet floor than a smooth floor. Why?
Answer:
Because friction on wet floor is far lesser than on a smooth floor
Explanation:
On wet surfaces, the friction is far lesser than on smooth surfaces and thus the grip between the bottom of your shoes/feet and the ground is very very small and as such walking on the wet surface becomes more difficult. Whereas on Smooth surfaces, there is plenty of friction and as a result, there is enough grip between the bottom of your shoes/feet and the ground thereby making walking far easier.
