i can statement
what is a evidence supporting continental drift
fossil evidence
what causes earthquakes and tsunamis
Earthquakes are due to sudden movement along fault lines inside the Earth.
Tsunamis are due to a sudden displacement of the ocean.
what is a convection
it is the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.
what is plate tectonics
what is it a scientific theory that explains how major landforms are created as a result of Earth's subterranean movements.
what is a
Ocean trench
it is a Ocean trenches are steep depressions in the deepest parts of the ocean where old ocean crust from one tectonic plate is pushed beneath another plate.
what is the theory of seafloor spreading
there is molten material that moves in at the boundaries between tectonic plates pushing them apart as new oceanic crust is created, and it expands the seafloor.
what are the types of the plate boundaries
convergent, divergent, transform
what is Continental drift,
what is Convergent plate boundary
Where tectonic plates converge, a plate capped by thin oceanic crust descends (subducts) beneath a plate with much thicker continental crust.
what is a pangea
it is a supercontinent that existed during the late Paleozoic and early Mesozoic eras.
what is the theory of plate tectonics
The Earth's outer shell is divided into large slabs of solid rock, called “plates,” that glide over Earth's mantle, the rocky inner layer above Earth's core.
what is the Divergent plate boundary
it is the occurs when two tectonic plates move away from each other
what is a Paleomagnetism
It is the study of the Earth's magnetic field as it is recorded in rocks, sediment, or archaeological materials.
what is a earthquake
it is a sudden and violent shaking of the ground, sometimes causing great destruction, as a result of movements within the earth's crust or volcanic action.
what is a
Rift
it is a a crack, split, or break in something.
How does convection in Earth’s mantle drive plate tectonics
In places where convection currents rise up towards the crust's surface, tectonic plates move apart, collide, or slide past each other.
what is a
Fault line
it is a line on a rock surface or the ground that traces a geological fault.
what is a magma
it is a hot fluid or semifluid material below or within the earth's crust from which lava and other igneous rock is formed on cooling.
what is a volcanic
earthquake is a volcanic
what is subduction
what are the different geologic phenomena to plate tectonics
They include mountain range formation, oceanic trench creation, Earthquakes, volcanic activity, seafloor spreading, continental drift, and movement of continents across the world.
what is lava
monten rock poured out by volcanoes in a liquid form.
what is the divergent plate boundary
it is the occurs when two tectonic plates move away from each other.
what is a tsunami
it is a long high sea wave caused by an earthquake, submarine landslide, or other disturbance.
what is a tectonic plates
what is it A tectonic plate (also called lithospheric plate) is a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic .
