The moon's altitude refers to its angular distance above the horizon. The moon's altitude changes throughout the night as it moves across the sky. At its highest point, the moon's altitude can reach around 90 degrees, which means it is directly overhead. The moon's altitude is an important factor for astronomers and navigators when determining its position in the sky. **

The legality of a flight altitude depends on various factors such as air traffic control regulations, airspace restrictions, and the specific flight plan. Pilots must adhere to the altitude restrictions set by air traffic control and comply with any airspace regulations in the area they are flying. Additionally, the aircraft's performance capabilities and the weather conditions also play a role in determining the legal flight altitude. Therefore, without specific details about the flight and the regulations in place, it is not possible to determine the legality of the flight altitude. **

Altitude difference refers to the vertical distance between two points, typically measured from sea level. It is the difference in elevation between the highest and lowest points in a given area. Altitude difference is an important factor in determining the topography and terrain of a region, and it can have significant effects on weather patterns, ecosystems, and human activities such as agriculture and transportation. **

Data can be transferred from one external device to another external device using various methods such as connecting the devices with a USB cable and transferring the data directly, using a wireless connection such as Bluetooth or Wi-Fi to transfer the data, or using a cloud storage service to upload the data from one device and then download it onto the other device. Additionally, data can also be transferred using external storage devices such as USB flash drives or external hard drives to physically transfer the data from one device to another. **

Yes, hackers can potentially access external data storage devices if they are able to gain unauthorized access to the device or the network it is connected to. This could be done through various means such as exploiting security vulnerabilities, using malware, or conducting phishing attacks to trick users into providing access. It is important for individuals and organizations to implement strong security measures such as encryption, access controls, and regular security updates to protect their external data storage devices from unauthorized access. **

The altitude at which a person can survive varies depending on factors such as acclimatization, physical condition, and individual tolerance. Generally, the human body can adapt to higher altitudes over time, but the threshold for survival without supplemental oxygen is typically around 18,000 feet (5,500 meters). Above this altitude, the air becomes too thin to provide sufficient oxygen for the body to function properly, leading to altitude sickness and potentially life-threatening conditions. However, with proper acclimatization and gradual ascent, some individuals can survive at even higher altitudes. **

Clouds float at various altitudes depending on their type. For example, cirrus clouds can be found at high altitudes of 20,000 feet or more, while cumulus clouds typically form at lower altitudes around 6,500 feet. Altostratus clouds are found at mid-level altitudes around 6,500 to 20,000 feet. Overall, clouds can be found floating at different altitudes in the Earth's atmosphere, ranging from low to high levels. **

The altitude at which one can survive varies depending on factors such as individual health, acclimatization, and the rate of ascent. Generally, humans can survive at altitudes up to around 18,000 feet (5,500 meters) without experiencing severe altitude sickness. However, prolonged exposure to altitudes above 26,000 feet (8,000 meters) without supplemental oxygen is not sustainable for most people due to the lack of oxygen at high altitudes. It is important to acclimatize properly and be aware of the symptoms of altitude sickness when ascending to high altitudes. **
