A Crater is a bowl shaped depression in the Earth's surface. It could be made by an impacting meteor, an underground land collapse, or perhaps may be found at the top of a volcano [= collapse].
A Caldera is of volcanic origin, (but without a noticeable volcanic cone), where there was an eruption after which the magma chamber collapsed and is now filled in. Yellowstone is one notable example, and the Taupo Lake another.
Crater: caused by impact (meteorite or asteroid) or at top of a volcano (caused by explosive eruption.)
Caldera: caused by ground collapsing, often as a result of a magma chamber underneath, but this is usually in the absence of a visible volcanic cone.
A caldera is a large, usually circular depression at the top of a volcano formed when magma is withdrawn. A volcanic crater, meanwhile, is small, circular depression created mainly by explosive excavation of rock during eruptions.
A caldera is a large crater, up to 50 kilometers, that can form when the summit or side of a volcano collapses into the magma chamber during of after an explosion. A crater is an indentation, only up to 1 kilometer in diameter, that forms around the central vent at the summit of a volcano. The main difference is size.
A cinder cone is a relatively small volcano characterized by mildly explosive eruptions that eject low-silica, relatively low-viscosity lava called basalt, mostly in chunks called scoria.
A caldera is a massive depression or crater formed by a very large, highly explosive eruption, usually associated with a stratovolcano. Calderas are associated with higher viscosity material such as dacite and rhyolite.
Craters only happen when a meteor hit Earth or other moons and planets. While caldera happen from volcanic activity.
A crater is the rim of a volcano, the main vent. A caldera is a depression caused by a collapsed magma chamber.
A crater can be a number of things, but there are a pair of definitions, one from geology and one from astronomy, that usually cover the bulk of the applications. A crater can refer to a volcanic crater (caldera), or it can refer to an impact crater resulting from a rock from space slamming into a planet, moon or other body. Links can be found below to help you sort it out further.
Caldera .
After its massive eruption in 1883, the volcanic island of Krakatoa collapsed into a caldera.
Calderas are formed by huge explosive volcanic eruptions. The magma chamber completely empties and the surface of the earth above it caves in forming a huge crater.
Crater
I actually had problems with this question on my crossword puzzle. The answer is actually a caldera. ---------------------------------- A volcanic crater would also be a correct answer.
a caldera
This is known as a Caldera.
It is called a crater. The area around the sides is the crater rim. If the volcano has collapsed into an empty magma chamber, this is called a caldera, and can exist for both tall or wide volcanoes.
A volcanic crater is a generally circular shaped depression.
A caldera is an extremely large version of a crater. Yellowstone National Park is enclosed in a volcanic caldera; the rim of it is disguised as lush, green mountains. Supervolcanoes are not the only volcanic systems with calderas, though. The island of Fogo, Cape Verde, is a caldera with a peak stratovolcano, Pico, at it's center. Also, Kilauea in Hawaii has a summit caldera. Craters, like Pu'u O'o (also in Kilauea) are much smaller, but are basically the same.

When a large explosive volcanic eruption destroys most of the volcano, the resulting large crater is called a caldera.
This may be a volcanic vent, crater or caldera depending on the specific volcanic event that formed the hole!
craters are usually caused by other things like small astroids, a caldera is caused by a volcanic chamber caving in.

It is called a caldera. It is a cauldron-like volcanic feature usually formed by the collapse of land following a volcanic eruption, such as the one at Yellowstone National Park in the US. They are sometimes confused with volcanic craters.(wikipedia). Hope that helped :-D
