When the weight of part of the Earth's crust changes what sometime occurs?
When the weight of part of the Earth's crust changes, it can lead to isostatic adjustments. This means that the crust will slowly adjust by rising or sinking to reach a new equilibrium. These adjustments can affect local sea levels, cause earthquakes, or create volcanic activity due to changes in pressure and magma movement.
What is the most abundant metal in earth?
Aluminum is the most abundant metallic element on Earth. It makes up more than eight percent of the earth's crust. Though, it is never free in nature. It combines with oxygen, sand, iron and titanium, and its ores are mainly bauxites.
Is the moon's crust thinner or thicker than Earth's?
The moon's crust is thinner than Earth's crust. The Moon's crust is estimated to be around 25 to 40 kilometers thick, while Earth's crust varies between 5 to 70 kilometers thick.
How is earth's crust different from the moon's crust?
Earth's crust is composed of multiple tectonic plates that float on the semi-fluid mantle below, while the moon's crust is one solid, unbroken layer, with no tectonic activity. Earth's crust is richer in elements like silicon and oxygen, while the moon's crust is mostly made up of different types of rock, such as basalt and anorthosite.
Why is the moon's crust thinner on one side than the other?
The pull of Earth's gravity during the moon's formation caused the crust on the far side of the moon to become thicker than the crust on the near side. On the near side, the lunar crust is about 60 km thick. On the far side, the lunar crust is up to 100 km thick.
If additional weight is added to a piece of crust how will the crust respond?
The crust will respond by adjusting its position to accommodate the additional weight. This may cause the crust to sag or deform if the weight is significant. Over time, the crust may undergo internal deformation processes to regain equilibrium.
If the estimated weight of the water in the Earth's oceans is 1.39 E 21 kg and the Earth's Crust is 4-7 mi thick how much additional weight can the ocean's crust handle before it becomes unbearable?
Because the Oceans spread their weight out evenly over the Earth, and the Crust is supported evenly from below by Earth's Mantle, the crust cannot "go" anywhere. True, it will compress somewhat from the weight of the oceans, but the oceans could be of any given depth (even a thousand miles) and the crust would do nothing but stay right where it is. Rock is heavier than water, so the continents outweigh the oceans by a considerable amount, even though they take up far less area. If the oceans were a couple of miles deeper, they would flood over the continents, but this would have little impact on their position.
If molten magma oozes out of the ocean floor and creates additional crustal material what will happen if there comes a time when there is too much crust?
New crust sometimes rides over existing crust, burying it, and sometimes it folds up, creating mountains.
When earthquake happen when these sections of earth crust move?
earthquakes happen when these sections of earths crust move
Does convection happen in the crust?
No. The crust is rigid; it does not allow convection.
What happen to the continental crust after the ice from the ice age melted?
After the ice from the ice age melted, the weight of the ice was removed from the continental crust. This caused the crust to gradually rebound or rise up due to the release of the pressure, a process known as post-glacial rebound or isostatic rebound. This uplift can continue for thousands of years after the ice has melted.
How does earths crust respond to addition and subtraction of mass?
When mass is added to Earth's crust, it causes the crust to subside and sink due to the increased weight. Conversely, when mass is removed from the crust, it can rebound and rise due to the decreased load. This process is known as isostatic adjustment and can result in changes in the Earth's topography.
What is the process of establishing a mew level of gravitational balance after weight is removed from or added to the crust?
When weight is removed from or added to the crust, the Earth's gravitational field adjusts to reach a new state of equilibrium. This process involves redistributing mass within the Earth to balance the gravitational forces. The adjustment may involve movement of material within the Earth's interior or changes in the shape of the Earth’s surface.
How many percent of oxygen comprises on weight of earths continental crust?
Oxygen comprises about 47% by weight of Earth's crust
What would happen if ocean crust and continental crust combine?
They weld together into new continental crust.
What is a pie breather?
A pie breather is a small weight (mine's a chicken! LOL) that u place in the middle of a raw pie crust when pre-cooking it. It keeps the pie crust from bubbling by releasing the air. (my chicken whistles - added bonus)
How can crust disappear at the edge of the boundary?
New crust is being added to the other edge of the boundary
