How abundant is platinum in the earths crust?
about 0.003 parts per billion in the earth's crust.
What is the age of the continental crust?
The age of the continental crust varies, but on average it is around 2.5 billion years old. This means that most of the continental crust is significantly older than the oceanic crust, which is constantly being recycled through processes like subduction.
How old is continental crust?
Continental crust is generally much older than oceanic crust, with some parts dating back over 4 billion years. The oldest known continental crust is found in regions like the Acasta Gneiss in Canada and the Nuvvuagittuq Greenstone Belt, which are estimated to be around 4.0 to 4.4 billion years old. However, most continental crust is typically between 1 to 3 billion years old.
How can Humans utilize the hot water produced within the earths crust?
it can be used for power, like geothermal
As oceanic crust moves away from the mid ocean ridge it cools and becomes more dense?
Yes, as oceanic crust moves away from the mid-ocean ridge, it cools and solidifies, causing it to become more dense. This denser crust then sinks lower in the mantle compared to the less dense asthenosphere, leading to the formation of the ocean basins.

Why pieces of earth's earliest crust do not exist today?
Earth's earliest crust, which formed over 4 billion years ago, has been recycled through processes like subduction, where it is pulled back into the mantle. This constant recycling of Earth's crust, along with the effects of erosion and weathering, means that no original pieces of the earliest crust remain intact today.
How old is the oldest continental crust?
The oldest continental crust is estimated to be around 4 billion years old. It can be found in regions like the Canadian Shield and parts of Western Australia.
What is the jigsaw like parts of the earths crust called?
Tectonic Plates
What composition is earths crust?
oceanic crust is made of basalt while continental crust is made of silica rich rocks like granite.
What are two sources of thermal energy in Earths interior?
Two sources of thermal energy in Earth's interior are residual heat from the planet's formation over 4.5 billion years ago and radioactive decay of elements like uranium, thorium, and potassium within the Earth's crust and mantle.
How many minerals make up the earths crust and what part of the crust do they make up?
Sounds like a homework question...
How does the age of the oldest continental crust compared to the age of the oldest oceanic crust?
The oldest continental crust would be between three and one half to four billion years older than the oldest oceanic crust. This is due to the fact that ocean plates are subducted under the continental plates, subjected to partial melt and essentially recycled in the mantle before reforming.
Is the oceanic crust older then the continental crust?
Well, the earth was built all by itself or more preferably god made it but, the oceanic crust and the continental crust are both aged the same. Whenever this earth was created like 40,000 or billion years ago. It's really quite simple to figure it out by yourself.
How many elements make up earths crust?
How many elements make up the earths crust? The earths crust is made of many layers..You can find clay and very good soil. But that is if you dig a little way down. the earth has a center which is called the core of the earth. Inside this core is lava and is incredibly hot. Like the sun but not as hot..
