A fallen rock.
A large mass of fallen rock is called a rockslide or landslip. It occurs when a significant amount of rock detaches from a steep slope or cliff and comes tumbling down due to gravity. Rockslides can be triggered by factors such as erosion, seismic activity, or heavy rainfall.
Most meteors result from meteoroids no more than a few centimeters in diameter. A larger meteoroid which survives the fiery passage through the Earth's atmosphere as a meteor and strikes the Earth's surface is called a meteorite.A meteoroid is a space rock floating in space. (If the space rock were large enough to see through a telescope from Earth, we would call it an "asteroid" instead.)When a meteoroid (a space rock) hits the Earth's atmosphere at anywhere from 25,000 miles per hour to 150,000 MPH, the speed of the rock's passage through the atmosphere causes some friction, which generates heat, and a whole lot of compression, which generates even MORE heat. This heats the space rock to incandescence, meaning "glowing hot". The streak of light in the sky from the glowing-hot space rock is called a "meteor".If the meteoroid was large enough, it may survive the passage through the atmosphere and impact the Earth. If the rock isn't entirely destroyed by the impact, then the surviving fragment is called a "meteorite".
No, inside a rock is not actually space. Rocks are made up of solid minerals and materials, with no actual empty space within them. The perception of space inside a rock may be due to the gaps between mineral grains or the presence of pores, but it is not the same as outer space.
The amount of space in a rock that holds air or water is called porosity. Porosity is a measure of the void spaces in a rock and can vary depending on the rock type and how compacted it is. It is an important factor in determining how easily fluids like air or water can flow through the rock.
It is called weathering.

A meteor is the streak of light caused by a space rock hitting the Earth's atmosphere and being heated to incandescence (white-hot) by friction and pressure. IF the rock survives the passage through the atmosphere and strikes the ground, we call it a meteorite. While a space rock is floating around in space, we sometimes call it a "meteoroid".
A meteorite is a rock that has fallen to Earth from space, while a terrestrial rock originates from Earth's crust. Meteorites often have a distinctive fusion crust from entering Earth's atmosphere, and may contain extraterrestrial materials like nickel-iron alloys or chondrules. Analysis of isotopic composition can also distinguish meteorites from terrestrial rocks.

Large amounts of fallen rock are called "talus."But Rock avalanche is a proper term, as is Rock slide, or rockfall.
