It varies tremendously as new crust is being created all the time (for example at erupting volcanoes and mid-ocean-ridges) which are literally creating crust as you read this, up to the most ancient continental "cratons", the very ancient interiors of continents such as the Canadian shield which may be anywhere in the range from about 3.7 to 4.28 billion years.

What are the major layers of earth's geosphere?
The major layers of Earth's geosphere are the crust, mantle, and core. The crust is the outermost layer and is divided into oceanic and continental crust. The mantle is situated beneath the crust and is composed of solid rock that can flow slowly over long periods of time. The core is located at the center of the Earth and is divided into the outer liquid outer core and the solid inner core.
What parts of Earth are solid?
The Earth's crust, which includes both the continental and oceanic crust, is solid. The Earth's mantle beneath the crust is also mostly solid, although it can flow slowly over long periods of time. The inner core of the Earth is solid due to immense pressure despite being extremely hot.
Is it true that earths crust movement has been taking place only during the past 1000years?
No, Earth's crust movement has been occurring for billions of years as part of the process of plate tectonics. The movement of the Earth's crust has shaped the planet's surface and continues to do so over long geological timescales.
What is the eath made of?
The Earth is composed of several layers: the crust, mantle, and core. The crust is the outermost layer and is made up of solid rock. Beneath the crust is the mantle, which is mostly solid but can flow slowly over long periods of time. At the center of the Earth is the core, which is composed mostly of iron and nickel.
Earth is created suddenly or do you think it was formed by long drawn and complex processes?
Earth was formed through a long and complex process over billions of years. Initially, it coalesced from dust and gas in the solar nebula, with gravitational forces pulling together matter to form a molten planet. Over time, this molten mass cooled, leading to the formation of a solid crust, oceans, and eventually an atmosphere. Geological and biological processes have continued to shape the planet since its formation, indicating that Earth's creation was anything but sudden.
How long does it take for oil to form in the Earth's crust?
Oil formation in the Earth's crust typically takes millions of years.
How thick is earth's crust in miles?
It is 25 miles long.
A long narrow crack in earth crust is called?
Fault
What are long cracks in the earth's crust called?
It's called a "fault"
How long does it take for a diamond to form in the Earth's crust?
Diamonds typically take millions to billions of years to form in the Earth's crust under high pressure and temperature conditions.
How long does it take for petroleum to form in the Earth's crust?
Petroleum forms in the Earth's crust over millions of years through the decomposition of organic matter under high pressure and temperature.
When was the first iceberg formed?
Sometime back in prehistory, when the Earth had cooled enough, and stayed cool long enough.
What is the layer of the earth right below the crust?
The layer of the Earth right below the crust is called the mantle. The mantle is more dense than the crust and is composed of hot, solid rock that flows slowly over long periods of time. It plays a crucial role in the movement of Earth's tectonic plates.
How long does it take for grape popsicle to harden?
It takes at least 3 days to harden.
What is the thickest section of Earth?
The thickest section of Earth is the mantle, which extends from the crust to the outer core. The mantle is made up of solid rock that flows over long time scales, and it accounts for about 84% of Earth's total volume.
Which two layers of the earth are made of rock?
The two layers of the Earth that are made of rock are the crust and the mantle. The crust is the outermost layer and is composed of solid rock, while the mantle lies just below the crust and consists of solid rock that is capable of flowing over long periods of time.
What are the major layers of earth's geosphere?
The major layers of Earth's geosphere are the crust, mantle, and core. The crust is the outermost layer and is divided into oceanic and continental crust. The mantle is situated beneath the crust and is composed of solid rock that can flow slowly over long periods of time. The core is located at the center of the Earth and is divided into the outer liquid outer core and the solid inner core.
