A piece of rock embedded in igneous rock is called a xenolith. Xenoliths are typically found in volcanic rocks such as basalt or lava flows.
a sample

The movement of a large block of soil and rock downhill in one piece when it becomes unstable is called a landslide. It can be triggered by various factors such as heavy rainfall, earthquakes, or human activities, causing significant damage to the surrounding area. Countermeasures like slope stabilization and drainage systems can help mitigate the risks associated with landslides.
