Break in earths crust where pieces of the crust move relative to each other?
A fault is a break in the Earth's crust where pieces of the crust move relative to each other. This movement can cause earthquakes as stress builds up along the fault line and is released suddenly. Faults are common in regions where tectonic plates interact and are essential for understanding earthquake hazards.
Which of earth's layers is the thinnest?
Crust
Describe the formation of block mountain and give example of a block mountain and rift valley?
Block mountains are formed when geological faults cause blocks of the Earth's crust to move vertically, leading to the formation of tall mountain ranges. An example of a block mountain is the Sierra Nevada in California, USA. Rift valleys, on the other hand, are formed by the stretching and thinning of the Earth's crust, leading to the development of deep valleys. The East African Rift Valley is a well-known example of a rift valley.
Where is the crust thicker oceans or continents?
The crust is typically thicker beneath continents compared to oceans. Continental crust can be up to 40 km thick, while oceanic crust is generally around 5-10 km thick.
Which element makes up half of the earth's crust?
OxygenOxygen is about 46% of Earth's crust.
How wide is the crust?
The Earth's crust can vary in thickness, but on average it is about 5-70 kilometers (3-44 miles) thick. However, it can be much thicker under mountain ranges and thinner under the ocean floor.
What is the size of the earths crust?
The Earths crust is approximately 650 km deep.
What causes the earths crust to rise and fall?
The sudden vibration in the plates inside the crust causes the earths crust to rise & fall.
Are all metals in the earths crust?
No, not all metals are found in the Earth's crust. While the Earth's crust contains a wide variety of metals, some metals are very rare and are not commonly found in geological formations. Additionally, some metals are found in concentrations that are too low to be economically viable for extraction.
