What else can I help you with?
How do scientist know that some places that once were under water and now deserts?
by rocks.
What factors control rocks returning to earths surface and becoming magma?
the heat of the volcano makes the rocks heat. the heat is the rocks the volcano blew up. now the rocks are a red hot liquid, the rocks rise to the surface because of the heat, it pops open the volcano top and makes a new island.
How is a caldera formed?
A caldera is formed when a volcano erupts violently, causing the emptying of the magma chamber below. The ground above the now-empty magma chamber collapses, creating a large bowl-shaped depression. This depression is further shaped by erosion and subsequent volcanic activity, resulting in a caldera.
Do metamorphic rocks contain layers?
well technically the first diamonds were made from magma before the earth was populated with people, but now the only way to make crystals(not diamonds) is from burning graphite, which is the only other substance completely made from carbon, like diamonds. so yes technically crystals are made from magma when it is spewed up from volcanos.
What department is once called the Department of War?
The Department of Defense was once called the Department of War.
How does lava push itself out from a volcano?
Lava pushes itself out from a volcanoe by building up at its state of building up it is actually called magma. The magma eventually builds up until it hits a weak spot in the land and the now called lava spews out. Really hope it helped. : D
What is melted rock?
Melted rock is that hasn't surfaced is "Magma".If the melted rock already has surfaced, it is called "Lava".
When metamorphic rock melts and turns into lava?
When metamorphic rock melts due to intense heat and pressure, it undergoes a process called partial melting. This transformation typically occurs in subduction zones or areas with high geothermal gradients. The molten rock, now called magma, can rise to the Earth's surface and erupt as lava during volcanic activity. This process contributes to the rock cycle by recycling materials and forming igneous rocks once the lava cools and solidifies.
How does sea floor spreading ocurr?
as convection currents cause more magma to rise the new magma forces apart the hardened material and like a conveyer belt continuously pushes older rocks aside
It was once a Dutch colony called New Amsterdam?
and now it's called new york
Does gneiss have fossils?
No, it's an igneous rock, made from cooling and consequently solidification of a magma. Animals (or any other organism) capable of leaving behind a fossil can not survive and do not live in a magma. Fossils can be found in sedimentary rocks or in metamorphic rocks (if the protolith, the original rock, was sedimentary). In metamorphic rocks, fossils are generally intensely deformed and hence difficult to recognise/identify.
What is the country called which was once Persia?
Persia is now known as Iran.
