1. Meteoroid

   A meteoroid () is a small rocky or metallic body in outer space. Meteoroids are defined as objects significantly smaller than asteroids, ranging in size from grains to objects up to a meter wide. Objects smaller than this are classified as micrometeoroids or space dust. Most are fragments from comets or asteroids, whereas others are collision impact debris ejected from bodies such as the Moon or Mars.When a meteoroid, comet, or asteroid enters Earth's atmosphere at a speed typically in excess of 20 km/s (72,000 km/h; 45,000 mph), aerodynamic heating of that object produces a streak of light, both from the glowing object and the trail of glowing particles that it leaves in its wake. This phenomenon is called a meteor or "shooting star". Meteors typically become visible when they are about 100 km above sea level. A series of many meteors appearing seconds or minutes apart and appearing to originate from the same fixed point in the sky is called a meteor shower. A meteorite is the remains of a meteoroid that has survived the ablation of its surface material during its passage through the atmosphere as a meteor and has impacted the ground. An estimated 25 million meteoroids, micrometeoroids and other space debris enter Earth's atmosphere each day, which results in an estimated 15,000 tonnes of that material entering the atmosphere each year.

1. meteoroid

   A meteoroid is a small rocky or metallic body in outer space that is significantly smaller than an asteroid. They are moving through space in orbit around the sun and often originate from the debris of comets and asteroids. When a meteoroid enters Earth's atmosphere and vaporizes, it becomes a meteor or shooting star. If it survives the passage through the atmosphere and lands on Earth, it is then classified as a meteorite.

1. Meteoroid

   A meteoroid is a small particle from a comet or asteroid. A meteoroid is significantly smaller than an asteroid, ranging from small grains to 1-meter wide. The visible streak of light from space debris is the result of heat as it enters a planet's atmosphere, and the glowing particles that it sheds in its wake is called a meteor, or colloquially a "shooting star" or "falling star". Many meteors appearing seconds or minutes apart, and appearing to originate from the same fixed point in the sky, are called a meteor shower. The root word meteor comes from the Greek meteōros, meaning "suspended in the air". Objects larger than several meters can explode in the air and create damage. If a meteoroid, comet or asteroid withstands ablation from its atmospheric entry and impacts with the ground, then it is called a meteorite. Around 15,000 tonnes of meteoroids, micrometeoroids and different forms of space dust enter Earth's atmosphere each year.

   It could be that more than one of these possible mechanisms are at play, for example, thermal fracturing could be chopping the surface material into small pieces, making it far easier for meteoroid impacts to launch pebbles into space.
