Atmosphere, geosphere, hydrosphere, and biosphere
All of Earth's water
What is hydrosphere?
What happens when Earthquakes occur?
seismic waves
the types of heat transfer
radiation, convection, and conduction
Measure of how much mass there is in a given volume of a substance
The ability to do work
What is energy?
All living things
What is biosphere?
How do Geologists learn about Earth's interior?
Evidence from rock samples AND Evidence from seismic waves
convection current
What is relatively soft layer if the upper mantle called?
asthenosphere
Earth's outermost layer and it a mixture of gases -- mostly nitrogen and oxygen
What is atmosphere?
What are constructive forces?
shape the lands surface by building up mountains and other landmasses
Name the 4 layers from the inside out.
inner core, outer core, mantle, and crust
What causes convection currents?
Heat from the core and the mantle
What is the transfer of heat by direct contact of particles?
conduction
What is a deconstructive force?
destroy and wear way landmasses through processes like erosion and weathering
The forces that cause lava to erupt are...
constructive forces
T/F Earths Core is made mostly of magnesium
False, nickel
Roasting marshmallows over a campfire is a type of what heat transfer
radiation
what is one result of convection currents in Earth's outer core?
Earth's magnetic field
What happens during feedback?
A system returns or "feeds back" data about a change in the system
forces that erode mountains
destructive forces
A layer of hot, solid rock below the crust
Heating a pot of soup on a stove (heated soup moves to cooler areas of soup)
convection
Which part of Earth's interior is made mostly of nickel and iron and has liquid and solid parts?
