The Earth's plates are lighter than the mantle. The top layer of the mantle is almost plastic in it's ability to bend and move without breaking. Heat from the interior of Earth appears to rise in currents through the mantle. The crustal plates ride on these currents as new crust is created at the mid-ocean ridges, and destroyed at oceanic trenches.

What causes continental plates to move?
Continental plates move due to the process of plate tectonics, where the plates float on the semi-fluid asthenosphere layer beneath them. This movement is driven by convection currents in the mantle, caused by heat from the Earth's core. When these currents push or pull on the plates, they cause them to move, leading to phenomena like earthquakes, volcanic activity, and the formation of mountains.
What is the relationship between plate tectonics and continental drift?
Plate tectonics is the scientific theory that explains how the Earth's outer shell is divided into several large, rigid plates that move and interact with each other. Continental drift is the idea that continents have moved and shifted positions over time. The relationship between plate tectonics and continental drift is that plate tectonics provides the mechanism for how continents drift and move around the Earth's surface. The movement of the plates causes the continents to shift and change positions, supporting the concept of continental drift.
What happens at a convergent plate boundary between an oceanic and continental plate?
At a convergent plate boundary between an oceanic and continental plate, the oceanic plate is usually denser and subducts beneath the continental plate. This can lead to the formation of deep oceanic trenches, volcanic arcs on the continental plate, and earthquakes due to the intense pressure and friction. Over time, the oceanic plate can melt and create magma that rises to form volcanic mountain ranges on the continental plate.
When an ocean plate collides with a continental plate it does what?
When an oceanic plate collides with a continental plate, the denser oceanic plate is subducted beneath the continental plate due to its weight. This subduction can lead to the formation of deep ocean trenches, volcanic arcs, and seismic activity.
What is an example of a continental to continental crust collision?
An example of a continental to continental crust collision is the collision between the Indian Plate and the Eurasian Plate that led to the formation of the Himalayan mountain range. This collision is ongoing and has resulted in the uplift of the Himalayas and the Tibetan Plateau.
How is theory of plate tectonics similar to the continental drift?
continental drift is caused by plate tectonics
When a continental plates collide with another continental plate what it is caused?
Earthquake
Continental drift is caused by?
plate tectonics
What happens in a continental plate?
the plates move apart
What type of boundary is the cascades?
The Cascade Range is formed along convergent plate boundaries. This is when plates move toward each other. more specifically the type of plate collision that caused the Cascades is an oceanic-continental convergence. This is when a plate with continental leading edge slowly collides with a plate that has an oceanic leading edge.
What can be caused by geologic plate move?
Earthquakes
What happens when a oceanic and continental plate move towards each other?
It is called a destructive plate boundry...one type of crust is oceanic and the other is continental. when they meet the oceanic crust gets pushed down as it is heavier. the friction caused when it sinks creates huge earthquakes and the crust re-melts and gets forced upwards due to pressure to form a volcano.
How non-volcanic mountains are created by plate tectonics?
Non-volcanic mountains are caused when continental plates converge.
What causes continental plates to move?
Continental plates move due to the process of plate tectonics, where the plates float on the semi-fluid asthenosphere layer beneath them. This movement is driven by convection currents in the mantle, caused by heat from the Earth's core. When these currents push or pull on the plates, they cause them to move, leading to phenomena like earthquakes, volcanic activity, and the formation of mountains.
What is is a Continental collision?
Convergent Continental collision is where two tectonic plates move towards each other and the plate that is more dense moves underneath the less dense plate.
What type continental boundary caused the Himalayas to be formed?
The Himalayas were formed by the collision of the Indian Plate with the Eurasian Plate. This is an example of a convergent boundary, where two plates move towards each other, resulting in the uplifting of the Earth's crust and the formation of large mountain ranges.
What is the process of a oceanic plate colliding with a continental plate?
Its when the oceanic crust and the continental crsut colide together.
