Get Section 9 4 Testing Plate Tectonics

The Earth's crust is broken into plates that are in constant motion over timescales of millions of years. Plates occasionally collide and fuse, or they can break apart to form new ones.

where are the youngest rocks on the ocean floor located? They found that the youngest rocks on the seafloor were at the mid-ocean ridges. The rocks get older with distance from the ridge crest. The scientists were surprised to find that the oldest seafloor is less than 180 million years old.

Tectonic plates, large slabs of rock that divide Earth's crust, move constantly to reshape the Earth's landscape. The system of ideas behind plate tectonics theory suggests that Earth's outer shell (lithosphere) is divided into several plates that glide over the Earth's rocky inner layer above the soft core (mantle).

The plates can be thought of like pieces of a cracked shell that rest on the hot, molten rock of Earth's mantle and fit snugly against one another. The heat from radioactive processes within the planet's interior causes the plates to move, sometimes toward and sometimes away from each other.

The ridge is part of a divergent plate boundary. The youngest rocks in the ocean floor are located at the mid-ocean ridges.

The oldest large-scale oceanic crust is in the west Pacific and north-west Atlantic — both are about up to 180-200 million years old. However, parts of the eastern Mediterranean Sea could be remnants of the much older Tethys Ocean, at about 270 and up to 340 million years old.

F: the youngest oceanic crust is found closest to the mid-ocean ridge.

How does mantle convection cause seafloor spreading? What happens to the continental crust when two continents collide? What happens at divergent plate boundaries in the continental crust? What are the moving plates of the Earth's crust called?

Palaeomagnetism is the study of the Earth's magnetic field preserved in rocks. The discovery that some minerals, at the time of their formation, can become magnetized parallel to the Earth's magnetic field was made in the nineteenth century.

The forces that drive Plate Tectonics include: Convection in the Mantle (heat driven) Ridge push (gravitational force at the spreading ridges) Slab pull (gravitational force in subduction zones)

The rigid lithospheric slabs or rigid and solid crustal layers are technically called plates. The whole mechanism of evolution, nature, and motions of plates, deformation within plates and interactions of plates margins with each other is collectively called tectonic plates.
