VOLCANOES
WHAT IS MAGMA
is composed of molten rock and is stored in the Earth's crust
WHAT IS THE ROCK CYCLE
rocks form deep in the Earth, move and sometimes change
WHAT IS WEATHERING
THE PHYSICAL AND CHEMICAL PROCESSES THAT BREAK DOWN ROCK
WHAT IS SEDIMENT
•matter that can be transported by fluid flow and which eventually is deposited as a layer of solid particles on the bed or bottom of a body of water
WHAT IS A TILTMETER
TOOL/INSTRUMENT USED TO DETECT VOLCANO ACTIVITY
WHAT IS LAVA
•magma that reaches the surface of our planet through a volcano vent.
WHAT ARE THE 3 TYPES OF ROCKS
•Metamorphic
•Sedimentary
•Igneous
WHAT IS EROSION
•Erosion happens when rocks and sediments are picked up and moved to another place by ice, water, wind or gravity.
WHAT IS THE PROCESS OF DEPOSITION
•Deposition is a process in which sediments, soil and rocks are added to a land form or land mass.
WHAT ARE THE 2 TYPES OF VOLCANO ERUPTIONS
QUIET AND EXPLOSIVE
WHAT IS THE RING OF FIRE?
Ring of Fire, a long horseshoe-shaped seismically active belt of earthquake epicenters, volcanoes, and tectonic plate boundaries that fringes the Pacific basin
WHAT IS A METAMORPHIC ROCK
•The original rock is subjected to very high heat and pressure, which cause obvious physical and/or chemical changes.
WHAT ARE THE 2 TYPES OF WEATHERING OF ROCK
Mechanical and Chemical Weathering
WHAT IS MASS MOVEMENT
TRANSFER OF ROCK AND SOIL DOWN A SLOPE OR MOUNTAIN DUE TO GRAVITY
DEFINE SOIL
•Soil is a mixture of organic matter, minerals, gases, liquids, and organisms that together support life.
WHAT ARE THE 3 TYPES OF VOLCANOES
COMPOSITE, SHIELD COMPRESSION
WHAT IS A SEDIMENTARY ROCK
Over time, these layers are squashed under more and more layers. Eventually, the layers are lithified – turned to rock.
WHAT IS CHEMICAL WEATHERING OF ROCK
•Chemical weathering involves a chemical change in at least some of the minerals within a rock.
WHAT PROCESS OCCURS FIRST IN THE ENVIRONMENT.....EROSION OR WEATHERING
WEATHERING
LIST 4 TYPES OF SOIL
CLAY, DIRT, SAND, SILT, GRAVEL, POTTING SOIL, SEDIMENT
WHAT ARE THE THREE PHASES A VOLCANO CAN BE IN
ACTIVE, DORMANT, EXTINCT
WHAT IS AN IGNEOUS ROCK
Igneous rock is formed when magma cools and solidifies, it may do this above or below the Earth's surface.
WHAT IS MECHANICAL WEATHERING OF ROCK
•Mechanical weathering involves physically breaking rocks into fragments without changing the chemical make-up of the minerals within it
