What else can I help you with?
Why isn't new oceanic crust generated along volcanic island arcs?
At a volcanic island arc, an oceanic plate slides into the mantle and thus oceanic crust is destroyed. The volcanoes add material on to of the crust, but to not cause the crust to expand outward.
Does seafloor spreading cause the earth's crust to expand?
Yes, seafloor spreading is a process where new oceanic crust is formed at mid-ocean ridges, causing the Earth's crust to expand. This occurs as magma rises to the surface, solidifies, and pushes older crust away from the ridge, creating new seafloor.
Opposite of decrease?
Increase, expand, develop.
When was Expand Networks created?
Expand Networks was created in 1998.
When was EXPAND-TB created?
EXPAND-TB was created in 2009.
When was Expand Your Head created?
Expand Your Head was created in 1988.
Why do bags expand when you go in the mountains?
Because of the decrease in theatmospheric pressure.
Does water expand when turned to ice?
Yes. This increases its volume, which results in a decrease in its density.
Does the volume of a gas decrease as the pressure decreases?
no it increases because it has more room to expand
Why does density decrease as temperature increases?
As temperature increases, the particles in a substance move faster and spread out more, causing the substance to expand and decrease in density.
Why must the production and destruction of the lithosphere be going on at the same rate?
New lithosphere is constantly being produced at the oceanic ridges. Lithosphere is consumed at the subduction zones. A balance is maintained because older, denser proportions of oceanic lithosphere descend into the mantle at a rate equal to seafloor production.
What is the opposite of expanding?
The opposite of expand is contract (in some uses, to shrink).For expand (increase), the opposite can be reduce or decrease.For expand (widen), the opposite would be to narrow.For expand (inflate) the opposite would be to deflate.
