Volcanoes are constructive forces in that they create new land, fertilize existing lands and bring many new minerals to the surface of the planet. Volcanoes also bring heat to the areas surrounding them and attract wildlife on land and beneath the sea.Continue Reading
Volcanoes create new land when molten rock, or magma, flows up from inside of the planet. The magma emerges as lava, and as it cools, it solidifies into rock again and creates new land. In the case of island volcanoes, these lava flows extend the edges of the island out into the ocean. However, just as with land-based volcanoes, many developed areas are also covered in lava during the process.
Volcanic rocks, when worn down and weathered into the dirt, create rich soils that are ideal for farming a variety crops. Volcanic eruptions also bring precious metals and minerals to the surface where it can be harvested, such as gold, silver, sulfur and diamonds.
Volcanoes also construct amazing structures at the bottom of the deepest parts of the ocean. These volcanoes often form gigantic underwater structures of condensed minerals, and some grow large enough to reach up and out of the sea to form entirely new islands. Volcanoes are also constructive to scientists and their overall understanding of the internal workings of the planet.Learn more about Volcanoes
The force of gravity on Uranus is 8.69 meters per second squared, which is also the speed at which dropped objects accelerate toward the surface of the planet. On Earth, objects accelerate at 9.78 meters per second squared. Uranus' gravity is approximately 89 percent of the force of Earth's gravity.Full Answer >
The Lut Desert is the hottest desert on Earth, based on satellite calculations that measure the land skin temperature of the entire surface of the planet. The 2005 reading of the Lut Desert was 159.3 degrees Fahrenheit. The Lut Desert is located in the southeast of Iran.Full Answer >
Clay volcanoes are a fun and simple way to exhibit the propulsive forces of volcanoes around the world. Making clay volcanoes is a simple project that can be completed in a few short hours.Full Answer >
Volcanic eruptions can affect the atmosphere and climate in the immediate vicinity of the volcano and also around the entire planet if the eruption is large enough. The main effect eruptions have on the weather near the volcano is producing large amounts of thunder, lightning and rain.Full Answer >
