Geology 111 First Exam 2026 Exam
Questions and Answers | A+ Score
Assured
Magma - 🧠 ANSWER ✔✔A molten mixture of rock-forming substances,
gases, and water from the mantle
oceanic crust - 🧠 ANSWER ✔✔thinner, more dense, younger crust making
ocean floor
inner core - 🧠 ANSWER ✔✔A dense sphere of solid iron and nickel at the
center of Earth
Lithosphere - 🧠 ANSWER ✔✔A rigid layer made up of the uppermost part
of the mantle and the crust.
,Isostacy - 🧠 ANSWER ✔✔The concept that Earth's crust is floating in
gravitational balance upon the material of the mantle.
igneous rock - 🧠 ANSWER ✔✔a type of rock that forms from the cooling of
molten rock at or below the surface
Metamorphic Rock - 🧠 ANSWER ✔✔rock that has been changed by heat
and pressure; can have banding (foliated) or no banding (non-foliated).
outer core - 🧠 ANSWER ✔✔A layer of molten iron and nickel that surrounds
the inner core of Earth
continental crust - 🧠 ANSWER ✔✔The portion of the earth's crust that
primarily contains granite, is less dense than oceanic crust, and is 20-50
km thick
Mantle - 🧠 ANSWER ✔✔The layer of hot, solid material between Earth's
crust and core.
Asthenosphere - 🧠 ANSWER ✔✔The soft layer of the mantle on which the
lithosphere floats.
Density - 🧠 ANSWER ✔✔mass/volume
, Sedimentary rocks - 🧠 ANSWER ✔✔Formed when particles of broken rock
and organic materials are pressed and cemented together to form new
rocks. Sediments are mud, sand, pebbles, shells, bones, leaves, and
stems. Some rocks of this type can be sandstone, limestone, and gypsum.
Hydrothermal rocks - 🧠 ANSWER ✔✔rocks that precipitate directly from hot
water
How thick is the crust? - 🧠 ANSWER ✔✔5 to 100 km thick
What part of the Earth is a liquid? - 🧠 ANSWER ✔✔outer core
What part of the earth is solid? - 🧠 ANSWER ✔✔inner core
What are the different types of mantle? - 🧠 ANSWER ✔✔The upper mantle,
transition zone, lower mantle
Difference between lithosphere and asthenosphere? - 🧠 ANSWER ✔✔-
Lithosphere is the outermost part of earth rigid tectonic plates.
-Asthenosphere is the upper mantle below lithoshpere and it flows as a soft
solid.
