Instead of soil, these plants attach(缠绕) themselves to things like trees, rocks and buildings. 5. Jessica Damiano, a gardening writer, has experience in growing air plants and offers the following guidelines to people who want to grow them. Sunlight Air plants require bright, indirect light.

But that can change very quickly if an avalanche happens. An avalanche is quite a lot of snow, ice and rocks moving quickly down a mountain, usually on slopes(斜坡) of 30 to 45 . It can move at speeds at 96 km/h to 129 km/h. Different things can make avalanches happen suddenly. About 90% of avalanches happen because of human activities, like climbers and snowmobiles(雪地摩托车). Strong winds, earthquakes, and even animal activities can also make them happen. Avalanches happen all year round. Most of them are small, but in high mountains, such as the Alps and the Himalayas, they can be very large and dangerous. When it happens, the fast-moving snow, ice and rocks can cover people, all the houses and villages along the way. When it stops, the snow becomes too hard to move. That can make people under it die of the cold. What can we do to keep safe if we want to climb snowy mountains? Education and proper training can help. They can give us useful advice. For example, never start climbing when the snow begins melting(融化), especially in spring. Avalanches may happen in this season at any minute. Wait for at least 2 days to start climbing after a snowstorm. Bring useful tools, like a beacon(信号灯) to help others find you. Phones sometimes don't work on mountains. Keeping quiet on the mountains is also important. Anyway, avalanches are part of nature. We need to have respect for the mountains and weather all the time. 5.
