You are on the ground in Denver (the mile high city) :)

Altitude is the distance above ground-level that an object is, in a vertical direction (that is, directly away from the centre of the Earth). If this is negative then the object is below ground-level, so it is underground.
Not directly. But changes in wind speed and direction in altitude, called wind shear, plays an important role in tornado formation.
Azimuth = 315° (True) Altitude = 0
Critical Mach Number has nothing (directly) to do with altitude. Mach Number has everything to do Temperature,
Altitude and elevation do not directly affect body weight in terms of actual mass. However, at higher altitudes, the air is thinner, leading to a decrease in air pressure. This can cause individuals to feel lighter or experience decreased appetite due to changes in their body's metabolism and oxygen levels. Additionally, some individuals may experience temporary fluid loss at higher altitudes, which might lead to a slight decrease in weight.
Mexico City has a subtropical highland climate (Köppen Cwb), due to its tropical location and high elevation of 2,240 meters (7,349 feet) above sea level. The average annual temperature varies from 12 to 16°C (53 to 60°F), depending on the altitude of the borough.
How high the sun is in the sky. The angle between the horizon and the sun. When the sun is directly overhead (eg, at the equator) the solar altitude is 90°. In Canberra in winter, the solar altitude is 30°.
The higher you go, the lesser the air pressure becomes. This can be logically understood. Atmospheric air pressure is caused by the weight of the air above it. At greater heights, the amount of air above you is less, so there is less weight pressing on the air you are in. This is the reason why the atmospheric pressure is higher at the sea-levels and lower at mountains and places of high altitudes.
As altitude increases, temperature decreases, hence why it often snows on mountains. This is due to the Greenhouse Effect, because rays from the sun reflect off the ground and travel upwards. Therefore, the sun most directly hits at sea level. Since the air is more dense at lower altitudes it more easily retains this heat.
DIRECTLY East.
Friction in the opposite direction to the direction of motion. Weight directly downwards. Reaction force directly upwards.
Directly opposite the center of the earth.
