what type of weathering is ice wedging
mechanical weathering
How do the fault lines contribute to volcanoes/earthquakes?
As the plates grind together they get stuck and pressure builds up
are volcanoes or earthquakes a sudden or gradual change?
sudden
What is ice wedging?

How thick is the mantle?
2900km
How many parts of the mantle are there?
2
How many parts does the mantle have?
2- a solid upper part and a slightly melted lower part
What is under the crust
Why is there lots of activities in the ring of fire?
because of the amount of movement of tectonic plates in the area
What does the Richter scale measure?
the severity and strength of an earthquake
What is the outer core made of?
liquid iron and nickel
What is the temperature of the inner core?
approx 6000 C
what does a seismograph do?
What is biological weathering?
damage caused by the movement of plant or animals
What is the inner core believed to be made out of?
iron and nickel
What is chemical weathering? and give example
erosion of material, rust on metal
How do glaciers move?
Wiggles slowly bit by bit, weight on top of the glacier makes the bottom putty like, enabling it to move slowly.
What type of weathering is it when a tree splits a rock?
biological weathering
How are glaciers made?
from accumulation of snow over long period of time
When rocks, minerals, or other things are moved from one place to another by some type of weathering this movement is called?
deposition
What is a surveyors level?
Instrument used to measure height differences that helps geologists determine whether a volcano is about to erupt or what it is doing
