what is a divergent boundary
a divergent boundary or divergent plate boundary is a linear feature that exists between two tectonic plates that are moving away from each other.
what happens at a convergent boundary
two tectonic plates collide, which can cause one plate to sub duct beneath
define the lithosphere
The rigid outer part of the earth, consisting of the crust and upper mantle.
Define the Athenosphere
define transform boundary
A transform fault or transform boundary, is a fault along a plate boundary where the motion is predominantly horizontal.
example of divergent boundry
What is subduction
subduction is when one plate sinks beneath another
how is the lithosphere different from the asthenosphere
the lithosphere is solid and bristle while the asthenosphere is softer
how does the asthenosphere affect plate tectonics
do transform boundaries create or destroy the crust
neither it creates new crust
which geological features are formed from divergent boundaries
Mid ocean ridges, rift valleys
What happens when two continental plates collide
they crumble and push upward
How thick is the lithosphere
50 to 100 km thick
at what depth is the asthenosphere found
100 km and 350 km
what geological activity is common in transform boundary.
earthquakes
How does magma rising from the mantle contribute to seafloor spreading
magma rises through gap between plates
What is an example of a convergent boundary on earth today?
The boundary between the Indian plate and the Eurasian plate which formed the Himalayan mountains
what is the role of the role of the lithosphere and the plate tectonics
the lithosphere is broken into tectonic plates
why is the asthenosphere important to mantle convection.
its thee region where heat driven convection is founded
what landforms are typically associated with transform boundary.
long fault lines
What is an example of a location on earth where a divergent boundary is occurring today
The mid Atlantic ridge and north American plates
which geological features are commonly formed at convergent boundaries
trenches, volcanic arches, and mountain ranges
what are 2 types of lithosphere
oceanic and continental
what is the physical state of the asthenosphere
solid hot rock
what is an example of transform boundary on earth today
san andreas fault lines
