What is formed when magma begins to form a dome shape which will push the crust outward in a hill formation?
A+ Laccolith
Which one of these pushes the overlying rock into a dome shape Batholith or laccolith?
A laccolith pushes the overlying rock into a dome shape. It is a type of intrusive igneous rock formation that is formed when magma pushes its way into the layers of overlying rock but does not reach the surface. The pressure causes the rock layers above to uplift and form a dome-like structure. Batholiths, on the other hand, are large underground bodies of igneous rock that can cover an area of several hundred square kilometers but do not typically create a dome shape.
What factors control the cooling time of magma within the crust?
The depth of the instrusion, the shape and size of the magma body, the presence of circulation groundwater.
Why is magma intrusive?
Magma is molten rock that comes from a layer miles beneath the Eart's crust. When underground pressures force magma upward, it "intrudes" into fissures within the solid rock, separating the layers of rock with "intrusive magma" that does not reach the surface. When magma erupts out of a volcano, it is "extrusive" and forms either "lava" that flows onto the ground, or "ejecta" that explodes into the air (before falling to the ground as volcanic ash). Intrusion or extrusion of magma produces "igneous" rock, which very different from rock which is produced by dissolved "sediments" accumulating at the bottom of rivers, or "metamorphic" rock which changes its shape and internal structure due to extreme pressures.
How does the shape of volcano affected by the flow of lava?
Basically the way volcanoes errupt is determined by two factors 1) The amount of gas dissolved in the magma. 2) The viscosity of the magma - which is in turn determined by the temperature of the magma and how basic or acidic its composition is. Runny magmas are usually basic and thick magmas are usually acidic. The amount of magma (available to erupt) in the higher level magma chambers also has some effect on the eruption progress, as does the shape and stability of the volcano (e.g. with Mt St Helen's one side of the volcano collapsed, exposing the magma chamber).

What is the definition of a volcano magma chamber?
A volcano magma chamber is a large underground reservoir that holds molten rock (magma). It is a key component of a volcano's plumbing system and acts as a storage unit for magma before it is eventually erupted to the surface. The magma chamber is typically located beneath the volcano and can vary in size and shape.
What is the shape of a gaggles flight formation?
A V shape.

How do rocks get their shape?
There is no shape for an rock they just form by them selves when magma cools down.
How does the shape surface area and volume affect how fast magma cools?
The shape affects the ratio of surface area to volume. The greater the surface are to volume ratio, the faster the magma will cool.
What is the strongest shape underground Catenary or Hemisphere?
sphere
What formatian do geese fly in?
Migrating Canada Geese fly in a loose V formation.
What is sirius's formation?
Sirius takes shape as a dog
What is the study of formation and shape of mountains called?
The study of the formation and shape of mountains is called geomorphology. Geomorphologists study the processes that shape the Earth's surface, including the forces that create mountains such as tectonic activity, erosion, and weathering. By analyzing the topography of mountainous regions, geomorphologists can gain insights into the geological history and ongoing processes that shape these landscapes.
Silica-rich magma erupts from the shield volcanoes giving them there broad flat shape?
False. The magma of shield volcanoes is silica-poor.
What factors control the cooling time of magma within the crust?
The depth of the instrusion, the shape and size of the magma body, the presence of circulation groundwater.
