Earth's Surfaces
The outermost layer of the Earth
This is where the earthquake first happens underground
What is the focus?
These are the three types of weathering
What are mechanical, chemical and biological?
The transportation of the products of weathering from place to place
What is erosion?
This causes an earthquake
The solid upper part of the mantle and the crust form this
What is the lithosphere?
This is right above the focus, the strongest part of the earthquake
What is the epicentre?
This is an example of weathering in Drumheller, Alberta
What are the hoodoos?
Products of weathering are laid down or deposited by wind, water or ice
What is deposition?
Moving masses of ice and snow that carry rocks around
What are glaciers?
A scientist who studies the Earth
What is a geologist?
What is the Richter scale?
Rock is broken down by physical forces such as water or wind
What is mechanical weathering?
Sudden and fast movements of rock and dirt down a slope
What is a landslide?
What volcanoes release
What are solid and molten rock, gases and ash?
This is the reason the outer core is molten
What is high temperatures?
These are the rumblings you feel during an earthquake
What are seismic waves?
New minerals or acids weather away at rocks
What is chemical weathering?
Silt, sand, mud, or gravel that is carried around by rivers
What are sediments?
Openings of earth's crust
What are volcanoes?
The inner core is solid because of this
What is pressurization?
This chart measures the strength of seismic waves
What is a seismograph?
Tree roots breaking down rocks
What is biological weathering?
The process of sediments being deposited, usually at the bottom of lakes, rivers, oceans
The layer of solid rock beneath the loose rock fragments (bonus)
What is bedrock?
