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.

100

what happens at a convergent boundary 

two tectonic plates collide, which can cause one plate to sub duct beneath 

100

define the lithosphere

The rigid outer part of the earth, consisting of the crust and upper mantle.

100

Define the Athenosphere  

the upper layer of the earth's mantle, below the lithosphere, in which there is relatively low resistance to plastic flow and convection is thought to occur.


100

define transform boundary

A transform fault or transform boundary, is a fault along a plate boundary where the motion is predominantly horizontal.

200

example of divergent boundry

  • The Mid-Atlantic Ridge.
  • The East Pacific Rise.
  • The Gakkel Ridge/ Mid-Arctic Ridge.
200

What is subduction 

subduction is when one plate sinks beneath another 

200

how is the lithosphere different from the asthenosphere 

the lithosphere is solid and bristle while the asthenosphere is softer

200

how does the asthenosphere affect plate tectonics

the movement of it allows the plates to move over top
200

do transform boundaries create or destroy the crust 

neither it creates new crust 

300

which geological features are formed from divergent boundaries 

Mid ocean ridges, rift valleys 

300

What happens when two continental plates collide 

they crumble and push upward 

300

How thick is the lithosphere 

50 to 100 km thick


300

at what depth is the asthenosphere found

100 km and 350 km

300

what geological activity is common in transform boundary. 

earthquakes

400

How does magma rising from the mantle contribute to seafloor spreading 

magma rises through gap between plates

400

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 

400

what is the role of the role of the lithosphere and the plate tectonics 

the lithosphere is broken into tectonic plates


400

why is the asthenosphere important to mantle convection.

its thee region where heat driven convection is founded

400

what landforms are typically associated  with transform boundary.

long fault lines 

500

What is an example of a location on earth where a divergent boundary is occurring today 

The mid Atlantic ridge and north American plates 

500

which geological features are commonly formed at convergent boundaries

trenches, volcanic arches, and mountain ranges

500

what are 2 types of lithosphere 

oceanic and continental 

500

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
