Earth Formations
A super-tall, rocky landform that rises high above the surrounding ground.
What is a mountain?
The process in which Earth's three main rock types—igneous, sedimentary, and metamorphic—continuously transform into one another over millions of years.
What is the rock cycle?
How many layers does the Earth have?
Four (main layers)
An opening in the Earth's crust that allows hot, melted rock, ash, and gases to escape from deep underground.
What is a volcano?
What does the "W" in W.E.D, stand for?
Weathering
A long, low area of land that sits between higher lands, like mountains or hills.
What is a valley?
The rock/mineral that is at a hardness level of 1
What is talc?
The outer most layer of the Earth.
What is the Earths crust?
Is the expulsion of molten rock (lava), gases, and debris from the Earth's interior through a vent onto the surface or into the atmosphere
What is an eruption?
What does the "E" in W.E.D, stand for?
Erosion
A super deep, narrow valley with very steep, rocky walls, often formed by a river flowing at the bottom.
What is a canyon?
The process of absorbing invisible or specific colors of light and glowing with a different color.
What is fluorescence?
When two plate boundaries push together causing one of them to go under the other.
BONUS: When two plates push towards each other.
What is subduction?
BONUS: Convergent boundaries
Is when smaller crystals are created.
What is rapid cooling?
What does the "D" in W.E.D, stand for?
Deposition
a piece of land that is completely surrounded by water.
What is a island?
A hollow, unassuming rock that conceals a brilliant cavity lined with inward-pointing crystals or layered mineral matter.
What is geode?
What state of matter is the mantle?
Liquid/Solid
An opening in the Earth's crust where magma, gases, and fragmented rock erupt onto the surface.
What is a volcanic vent?
The main cause of weathering.
What is water?
A tall, flat-topped hill with steep, cliff-like sides.
What is a mesa?
The point of where a crystal starts to form.
What is the nucleus?
This is how heat moves through liquids (like water) or gases (like air).
What is Convection?
A cloud of tiny, sharp pieces of rock, minerals, and volcanic glass blasted into the air during a volcanic eruption.
What is volcanic ash?
The process by which transported sediments, soil, and rocks are laid down, or dropped, in a new location.
What is deposition?
