Yes.
When the distance between the object's centers of mass increases, the force of gravity weakens (this can be measured experimentally on Earth at low elevations and high elevations with a sensitive pendulum and an accurate clock).
Mass does not change with changes in altitude or elevation. Weight on the other hand does change. However, on earth the change from sea level to the top of a mountain would be extremely small.
It is the other way round - gravity varies with altitude. In other words, you should consider altitude the independent variable. At a greater altitude, there is less gravitational force. This is explained by the equation - F(g) = G(m1m2)/(r^2) where G = constant, m1 and m2 = mass, F(g) = force due to gravity, and r = distance from center of mass. The altitude difference covered by humans daily (high buildings, hills) makes only a small, probably negligable difference in force due to gravity.
Air pressure falls of as one gains altitude. At high altitude the air pressure is very low but it does not "falls drastically", which implies a sudden change.
Yes, altitude can affect specific gravity and density due to variations in atmospheric pressure. As altitude increases, atmospheric pressure decreases, leading to a decrease in density and specific gravity of gases and substances. This is important to consider when measuring and calculating these properties at different elevations.
Above 100,000 feet altitude (20 miles).
Because of less gravity in high altitude
Mass does not change with changes in altitude or elevation. Weight on the other hand does change. However, on earth the change from sea level to the top of a mountain would be extremely small.
At high altitude; you are further away from Earth's centre of mass, so the distance is greater and the force due to gravity is lessened.

If you are moving at different altitude the gravity will changes and so the weght will changes

To calculate gravity at any altitude, you can use the formula: gravity at altitude = acceleration due to gravity at sea level * (1 - 2 * altitude / Earth's radius)^2. The acceleration due to gravity at sea level is approximately 9.81 m/s^2, and Earth's radius is roughly 6,371 km. Substituting these values will give you gravity at your desired altitude.
Air pressure falls of as one gains altitude. At high altitude the air pressure is very low but it does not "falls drastically", which implies a sudden change.
Acceleration due to gravity remains constant regardless of altitude. Other factors such as air resistance or the presence of external forces can impact acceleration at different altitudes.
At what altitude does the Earth's gravity no longer have an effect on the astronauts or the space shuttle?
A pendulum can be used to measure altitude by observing the time it takes for the pendulum to complete a full swing. As altitude increases, the acceleration due to gravity decreases, causing the period of the pendulum to change. By measuring this change in period, one can determine the altitude.
