What are the two main types of parachutes used in skydiving?

The two main types of parachutes used in skydiving are ram-air and round parachutes. Ram-air parachutes, which are the most commonly used today, are designed with a wing-like shape, allowing for greater control and maneuverability during descent. This type of parachute inflates with air as it descends, creating lift and allowing the skydiver to steer and land with precision.

Round parachutes, on the other hand, are more traditional and take on a dome shape. They are generally used in specific scenarios, such as military jumps or situations where predictable descent rates are required. While they provide a reliable descent, they lack the maneuverability and performance characteristics of ram-air parachutes, which is why they are less favored in recreational skydiving.

The other options do not accurately categorize the main types used in skydiving. Square and circular parachutes refer more broadly to shapes and do not specify the functional designs used in modern skydiving. Conical and elliptical parachutes may describe certain less common styles, while static-line and freefall parachutes refer to the deployment methods rather than the parachute designs themselves. Thus, the focus on ram-air and round parachutes captures the essence of what's primarily used in skydiving
