Lava broad, shallow slopes formed from predominantly effusive eruptions of relatively fluid basaltic lava flows, to steeply-sided stratovolcanoes (also known as composite volcanoes) made of alternating layers of ash and more viscous lava flows typical of intermediate and felsic lavas. A caldera, which is a large subsidence crater, can form in a stratovolcano, if the magma chamber is partially or wholly emptied by large explosive eruptions; the summit cone no longer supports itself and thus collapses in on itself afterwards. Such features may include volcanic crater lakes and lava domes after the event. However, calderas can also form by non-explosive means
The floor is lava activity then becomes part of her long-term memory, creating a lake of lava inside her mind, filled with floating architecture. After being accidentally sent to long-term memory, two of her chief emotions, Joy and Sadness, must cross the lake in search of a way to return to their control headquarters.
