Colliding

New Zealand is known as "The Shaky Isles" because of its location on the margin of two colliding tectonic plates.

Presented in the style of vintage horror movie advertisements, the new posters feature a dead galaxy, an explosive gamma ray burst caused by colliding stellar corpses, and ever-elusive dark matter.

The two narrow energy beams seen in the gamma ray burst poster reflect how they occur in real life, travelling in opposite directions from the colliding stellar corpses.

Remove the camera now! I almost broke my hand colliding with it.

Dmitri and Rima’s elbows were colliding.

The bat swerved to avoid colliding with a tree.

The study also suggests such collisions could lead to significant atmospheric gains if the colliding object also has a thick atmosphere.

Hailstones are formed when raindrops are carried upward by thunderstorm updrafts into extremely cold areas of the atmosphere and freeze. Hailstones then grow by colliding with liquid water drops that freeze onto the hailstone’s surface. If the water freezes instantaneously when colliding with the hailstone, cloudy ice will form as air bubbles will be trapped in the newly formed ice. However, if the water freezes slowly, the air bubbles can escape and the new ice will be clear. The hail falls when the thunderstorm’s updraft can no longer support the weight of the hailstone, which can occur if the stone becomes large enough or the updraft weakens.
