what is the geological time scale?
a time scale of geological eras and their information
35
what are the layers of the earth?
crust upper manthle mantle outer core inner core
36
what causes earth movements?
forces within the earth when temperature and pressure differences cause instability
37
what are plate techtonics?
large sclae movvements of the earth's lithosphere and cause of the continental drift
38
what are the parts of the crust?
litosphere and asthenosphere
39

the lithosphere moving on the asthenosphere
40
what are the types of plate boundaries?
convergent/collision divergent/spreading transform
41
what is the pacific ring of fire?
an area of frequent earthquakes and voclanic erruptions in the Pacific Ocean
42
how do tectonic plates create mountains?
compressional forces, isostatic uplift, and intrusion of igneous matter forces surface rock upwards

the flow of water undergrownd
52
what is evaporation?
the transofrmation of water form liquid to gas as it moves from the ground to the atmosphere
53
what is condensation?
water vapor transofmed into liquid water in the air producing clouds and fog
54
why does weather occur?
temperature and moisture differences between different locations
55
what causes pressure differences?
