Altitude

Altitude refers to the height of an object above a reference point, which is typically the Earth's surface. In the context of geography and aviation, altitude is often used to describe the height of an object above sea level.

Types of Altitude

There are several types of altitude:

1. True Altitude: The vertical distance of a point above the mean sea level.
2. Absolute Altitude: The vertical distance of an aircraft or spacecraft above the Earth's surface.
3. Geopotential Height: The height of a pressure surface in the atmosphere, measured in units of length.
4. Indicated Altitude: The altitude read directly from the altimeter.
5. Pressure Altitude: The altitude in the International Standard Atmosphere at which the pressure is the same as the existing pressure.

Factors Affecting Altitude

Altitude is influenced by various factors such as:

• Geographical location
• Elevation of the land
• Atmospheric pressure
• Temperature

Effects of Altitude

Changes in altitude can have significant effects on living organisms and the environment. These effects include:

• Decrease in air pressure
• Thinner air with less oxygen at higher altitudes
• Impact on climate and vegetation
• Adaptations of organisms to high-altitude environments

Study Guide for Altitude
