When old rocks are partially melted or squeezed what rocks are formed?
When old rocks are partially melted or squeezed, they can form metamorphic rocks. Examples include gneiss, schist, and marble. These rocks exhibit new textures and compositions due to the heat and pressure they have experienced.
Where are the youngest rocks in sea-floor spreading?
The youngest rocks in sea-floor spreading can be found at the mid-ocean ridges, where new oceanic crust is formed. As tectonic plates pull apart, magma rises to the surface and solidifies, creating new rocks. These rocks are typically less than a few million years old.
How old are rocks in ocean crust?
The age of rocks in the ocean crust depends on where the rocks are collected. Scientists collected rock samples from the sea floor. They found out that rock samples that were closer to mid-ocean ridges were younger than the samples farther away from the ridges. So pretty much you could get rocks that are thousands of years old to over millions of year old.
Why are the oldest rocks found on earth younger than the oldest lunar rocks that Apollo brought back from the moon?
The Earth is still tectonically active and because Earth has weather. The tectonic activity refreshes the crust as some plates are forced under others, removing old rock from the surface, and things like the sea floor spreading and volcanic activity producing all new crust. Additionally, the weather on the Earth constantly works to erode existing crust and wash it into the oceans.The moon is neither terctonically active nor is there weather. The moon is, in planetary science terms, dead. There is no process to remove old surface rocks and replace with new ones.
What isotope is best for dating very old rocks?
Uranium-lead dating is often used for dating very old rocks, as it has a long half-life of about 4.5 billion years. This allows for dating rocks that are millions to billions of years old with good accuracy.
What does constructive?
Someone who is constructive makes new things or old things better. No just physical, but ideas also.
Are old things better than new things?
new things are better than old depending on what your talking about.
When was Old Things New created?
Old Things New was created on 2009-10-27.
In observing rock layers am usually found on the bottom. What am i?
Old rocks! New or young rocks are at the top!
Do rocks grow old?
Yes, a rock ages at a rate of 1 year per year. ANOTHER ANSWER: Rocks don't GROW. Rocks are not 'living beings'. Rocks are not born from seeds or from 'birth'. Only 'living things' age. Rocks GET old; just like your car GETS old. It deteriorates. Rocks WEAR-AWAY when exposed to the elements.
When old rocks are partially melted or squeezed what rocks are formed?
When old rocks are partially melted or squeezed, they can form metamorphic rocks. Examples include gneiss, schist, and marble. These rocks exhibit new textures and compositions due to the heat and pressure they have experienced.
Where are rocks found in New York?
Rocks can be found almost anywhere, sandstone can be found in beaches, granite is mostly found in New York city. I hear there might be some igneous rocks in central park.
How old are the rocks in garden of the gods?
the rocks are 67576million years old and some of the rocks are 13542million years old.
How old is the saying Out with the old in with the new?
The saying "Out with the old, in with the new" has been around for centuries, with variations appearing in different cultures and languages. It generally conveys the idea of replacing old things with new things and is often used to encourage change or new beginnings.
What is the process of which new rock forms from old rocks?
There are several ways by which old rocks can become "new" rocks, all of which are described by the rock cycle. A rock, no matter what class it falls under, can become igneous, metamorphic, or sedimentary. When melted and then re-cooled, a rock become igneous. When exposed to very high temperature and pressure, the rock becomes metamorphic. When weather or eroded by wind, water, etc., and then lithified (cemented together), the rock becomes sedimentary. Again, any rock can go from one class to the other, or in some cases become a new rock of the same class.
What candy or candy bar is decoupage that makes things look old?
Krackle
What is the rock cycle explain in kids' explanation?
Magma from the earth travels to the surface It hardens and makes mountains. Water breaks the mountains down over a long time The small bits of rock travel down rivers and go into the sea Over time, layers of rock form, called sedimentary rocks During this time, at depth, the pressure is high and so rocks get bent and form metamorphic rocks.
