What else can I help you with?
What force pushes out magma out of a volcano onto the surface?
Pressure.
How magma moves upward though a volcano and reaches the surface during an eruption?
The inside of the earth (Mantle) pushes the hot magma liquid and makes the magma move toward the surface.
What cause an eruption of an volcano?
The amount of pressure that pushes up the magma in a volcano
What causes magma beneath the volcano to rise to the surface?
Increasing pressure pushes the magma upwards. This rising pressure can be caused by many different things.
Are there forces acting on a car at rest?
Yes. Gravity pulls it down; the road, or any surface the car is resting on, pushes it up.
How is a volcano born?
A volcano is born when magma from beneath the Earth's surface rises and collects in a magma chamber. As pressure builds, the magma forces its way to the surface through a vent, resulting in an eruption. Over time, repeated eruptions can build up a volcano's cone shape.
When you swim what is the force of the water which pushes you toward the surface?
The buoyant force pushes you toward the surface.
What are the 2 forces that are not equal in size?
Gravity and the normal force exerted by a surface are two forces that are not always equal in size. Gravity pulls objects downward, while the normal force pushes back upward on an object to prevent it from sinking into a surface.
How does volcanoes from and erupt?
Volcanoes erupt when pressure from inside the earth pushes magma through a weakness in the earth's surface. As more and more magma erupts, the volcano is formed and grows.
What is the action and reaction forces when touching you finger to your nose?
There are two forces involved; the finger pushes against the nose, and the nose pushes against the finger.
What are two forces acting on a book?
Two forces acting on a book are gravity pulling it downwards towards the Earth and the normal force exerted by the surface it is resting on that pushes back against gravity to keep the book stationary.
What term in physical science are pushes and pulls?
Forces
