Large falling chunks of lava are known as "lava blocks" or "lava bombs." These are solid fragments ejected during volcanic eruptions, typically formed when volcanic gases expand and fracture the lava as it is expelled from a vent. Lava bombs can vary in size and shape, ranging from small pebbles to large boulders, and can cause significant damage upon impact due to their high temperature and kinetic energy. Their formation is common in explosive volcanic eruptions, where the force of the eruption propels the lava into the air.

Pahoehoe and a'a refer to different texutres of lava flows. Although cindercones can produce lava flows, their main mode of eruption is called "fire fountaining" which tends to produce chunks of lava called scoria, rather than pahoehoe or a'a.
Cinder cones produce ash and chunks of lava rock called scoria.
Asteroids and meteoroids are large chunks of rock and debris that resemble large chunks of rock in space. When they enter the Earth's atmosphere, they are called meteors or meteorites depending on whether they burn up or make contact with the surface.
Large chunks of Earth's crust are called tectonic plates. These plates float on the semi-fluid layer of the mantle and are responsible for movements like earthquakes, volcanoes, and mountain building.

A sedimentary rock composed of large chunks of other rocks cemented together is called a conglomerate. This rock forms when pebbles, cobbles, or boulders are transported by rivers or glaciers and later become cemented together through natural processes.
