In areas with volcanoes, engineers have designed homes with steep roofs so volcanic ash can slide off more easily. The roofs are also strong enough to withstand the added weight from the ash.
A volcano is an opening in Earth’s crust.
A volcano is an opening in the Earth that allows molten rock, called magma, from inside the earth to escape. When the magma escapes, it is called an eruption. Volcanoes are formed when molten rock from inside the earth works its way to the surface. Volcanic eruptions may be very destructive/
The Earth’s crust is made up of huge plates that move very slowly. Volcanoes are commonly found along the boundaries between these plates.
