The heat from radioactive processes within the planet’s interior causes the plates to move, sometimes toward and sometimes away from each other. This movement is called plate motion, or tectonic shift
What Causes the Ground to Move?
The ground we walk on seems so solid and unchanging. But, it is always moving. The ground moves in response to the forces placed upon it.
The most common force that moves the ground is gravity. Gravity is the force that pulls objects toward the center of the Earth. It is what makes things fall.
The force of gravity also affects the ground. The ground is constantly being pulled toward the center of the Earth by gravity. Gravity is not the only force that can move the ground.
The ground can also be moved by the force of an earthquake. Earthquakes are caused by the movement of the Earth‘s plates. The Earth‘s plates are like a giant jigsaw puzzle.
They fit together to make up the Earth‘s surface. The plates are always moving. They move very slowly, but they do move. Earthquakes happen when the plates move too much or too quickly.
The force of an earthquake can be very strong. It can move the ground several feet. The force of an earthquake can also cause buildings to collapse and roads to crack.
The ground can also be moved by the force of a landslide. A landslide is when a large amount of dirt, rock, and other materials move down a slope. Landslides can
