Geosphere
Give this one a try later!
the solid part of the earth consisting of the crust and outer mantle
Protosuns and Protoplanets
Give this one a try later!
, -formed from a contracting slowly spiralling nebula
-happened due to a collapse during which the gravitational energy was
converted to thermal energy causing the temperature to the inner portion
of the nebula to dramatically rise
Mesosphere (lower mantle)
Give this one a try later!
Increased pressure counteracts the effects of higher temps, and the rocks
gradually strengthen with depth. 660 km-2900 km deep.
- rocks are still hot and capable of very gradual flow, an essential
component of the heat transfer mechanism that drives plate tectonics
mantle convection
Give this one a try later!
a recurring current in the mantle that occurs when hotter, less dense
material rises, cools, and then sinks again. This current is believed to be one
of the driving forces behind tectonic plate movement.
