Volcano

Mount Kilimanjaro, the largest volcano in Africa, is a composite volcano which is tall and steep, and built up by many layers of hardened lava and volcanic ash. The reason why there are multiple layers is because composite volcanoes are constructed from multiple eruptions, sometimes recurring over hundreds of thousands of years. Lava from an active composite volcano can flow through cracks in the crater wall. Then, the lava hardens around the cracks andstrengthens it.
