GEOL 111 Exam 2 2026 EXAM
QUESTIONS AND ANSWERS | 100%
PASS
scoria cone - 🧠 ANSWER ✔✔a rather small volcano built primarily of
pyroclastics ejected from a single vent with hardened lava
composite volcano - 🧠 ANSWER ✔✔A tall, cone-shaped mountain in which
layers of lava alternate with layers of ash and other volcanic materials
Magma - 🧠 ANSWER ✔✔A molten mixture of rock-forming substances,
gases, and water from the mantle
lava fountain - 🧠 ANSWER ✔✔a jet of lava sprayed into the air by the rapid
formation and expansion of gas bubbles in the molten rock
,Tephra - 🧠 ANSWER ✔✔bits of rock or solidified lava dropped from the air
ash flow - 🧠 ANSWER ✔✔A mixture of volcanic ash, larger pyroclastic
particles, and gas that flows rapidly along the earth's surface as a result of
an explosive volcanic eruption.
Felsic - 🧠 ANSWER ✔✔Describes magma or igneous rock that is rich in
feldspars and silica and that is generally light in color.
Vesicular rocks - 🧠 ANSWER ✔✔This is when gas bubbles form in the rock
and can't escape because the magma around it is to thick.
Pahoehoe - 🧠 ANSWER ✔✔A hot, fast-moving type of lava that hardens to
form smooth, ropelike coils
volcanic bombs - 🧠 ANSWER ✔✔large blobs of magma that harden in the
air
Fissure Volcano - 🧠 ANSWER ✔✔A long, narrow volcano that forms at
cracks and weak points in the earth's crust.
shield volcano - 🧠 ANSWER ✔✔a wide, gently sloping mountain made of
layers of lava and formed by quiet eruptions
, volcanic dome - 🧠 ANSWER ✔✔rounded hill formed by slow-moving,
cooling lava
pyroclastic flow - 🧠 ANSWER ✔✔The expulsion of ash, cinders, bombs,
and gases during an explosive volcanic eruption
Viscosity - 🧠 ANSWER ✔✔A liquid's resistance to flowing
Mafic - 🧠 ANSWER ✔✔describes magma or igneous rock that is rich in
magnesium and iron and that is generally dark in color
Aa lava - 🧠 ANSWER ✔✔lava that hardens into rough, jagged rocks with a
crumbly texture
lava tube - 🧠 ANSWER ✔✔The empty space left when a lava tunnel drains;
this happens when the surface of a lava flow solidifies while the inner part
of the flow continues to stream downslope.
Caldera - 🧠 ANSWER ✔✔a large crater caused by the violent explosion of
a volcano that collapses into a depression
Startovolcano - 🧠 ANSWER ✔✔a concave-shaped volcano formed from
alternating layers of lava flows and beds of pyroclasts
