What are the 3 layers of earth
Crust,Mantle,and the Core
what are the three types of heat transfer
conduction, convection, and radiation
what is plate techtonics
a scientific theory that explains how major landforms are created as a result of Earth's subterranean movements
What are three examples of plate boundaries
divergent, convergent, and transform
What are ridges made of
edrock, loose sediment, lava, or ice
What is the 3rd layer of earth made of
Molten lava
What is conduction
when heat moves from one object to another object through direct touch.
How many major plates does the lithosphere have?
7 major
What can form a plate boundary
When two tectonic plate's meet
What are 5 examples of riges
Mid-Atlantic Ridge
Southwest Indian Ocean ridge
Central Indian Ocean ridge
Southeast Indian Ocean ridge
Pacific Antarctica ridge
What is the 1st layer of earth made up of
continental crust and oceanic crust.
What is radiation
Energy released in the form of particle or electromagnetic waves.
What makes heat rise
Fluids such as air and water typically become less dense when they are heated
What does plate boundaries Make
Volcanic Eruptions and shallow earthquakes
depositional, erosional, tectonic,
What is the 2nd layer of earth made of
silicate rocky material
What is convection
the movement of particles through a substance, transporting their heat energy from hotter areas to cooler areas.
How does mantle convection cause seafloor spreading?
heat from the mantle's convection currents makes the crust more plastic and less dense.
What do plate boundaries affect
a variety of earthquakes and a line of volcanoes on the overriding plate
What boundary causes ridges
divergent plate boundaries
how does the 2nd layer of earth affect the earth
drives plate tectonics, contributing to volcanoes, seafloor spreading, earthquakes, and orogeny (mountain-building
How is heat transfer related to temperature
For a gas, the heat transfer is related to a change in temperature.
What are 3 main reasons why convection is important
redistribute energy away from hotter areas to cooler areas of the Earth, aiding temperature circulation and reducing sharp temperature differences.
What is a plate boundary
A plate boundary is a three-dimensional surface or zone across which there is a significant change in the velocity (speed or direction) of motion of one lithospheric plate relative to the adjacent lithospheric plate
a geographical feature consisting of a chain of mountains or hills that form a continuous elevated crest for some distance.
