Fact...Landslides

Landslides carrying millions of tons of rubble can reach speeds of 100 mph, but leave the grass on the hill beneath them completely untouched. This is because air, trapped and compressed, acts as a cushion allowing the moving debris to travel a few inches above the ground.



Were we closer to the ground as children, or is the grass emptier now? ALAN BENNETT (1934- )
