(16 cards)
It is the physical removal of rock or wearing down of landmasses by
geomorphic agents such as running water, glacial ice and wind.
Erosion
t is the phenomenon related to various processes associated with the
surface discharge of magma or hot water and steam
Volcanism
It emit mixtures of steam and other gases such as
hydrogen sulfide which forms into a sulfuric and native
sulfur upon contact with other elements.
Fumaroles
It is a phenomenon on the surface where the ground
water beneath the shallow surface is heated up until it
explodes into boiling water and steam, then refills its
plumbing system with the fresh water and creating a
cycle that can be observed periodically like a matter of
minutes or hours
Geysers
It may occur in many geothermal areas where the
surface of the earth intersects the water table.
Hot spring
A typically a cone – shaped hill or mountain formed by
the extrusion of lava or ejection of rock fragments
from vent
Volcano
t is a passage or rupture through the earth’s crust
leading to hot deposits of magma within the mantle
Volcano
The process wherein magma escapes from Earth’s interior
to form a cool hard rocks known as igneous rocks.
Volcanism
pertains to a magma that finally reached the surface.
lava
When magma do not move out
from the opening of a volcano. Instead , magma flows along
the chamber inside the crust, and from there, it hardens to
become a rock.
intrusive
When lava flows on a surface
of Earth and as time goes by, lava cools and hardens, and it
becomes a rock. T
extrusive
are locations on Earth’s surface that has experienced active
volcanic activities for a long period of time.
hotspots
- areas or columns where heat or rocks in the mantle are
rising toward Earth’s surface.
mantle plumes
erupt fairly/frequently
active
eruption has been recorded in historical times
extinct or ancient
eruption has not occurred regularly recently
dormant
