Study Questions with Correct
Answers
1. Core - ANSWER Innermost zone. Dense mass made up of nickle and iron.
Solid inner and liquid outer.
2. Mantle - ANSWER Above core. Molten rock
3. Magma - ANSWER Molten Rock
4. Earth Systems - ANSWER the four main physical systems of the earth-
hydrosphere, lithosphere, atmosphere, biosphere
5. Astronomy - ANSWER The study of the moon, stars, and other objects in
space
6. meteorology - ANSWER the study of weather
7. geology - ANSWER the study of the origin, history, and structure of Earth
8. Oceanography - ANSWER the scientific study of the oceans and oceanic
phenomena
9. Environmental Science - ANSWER The study of the natural processes that
occur in the environment and how humans can affect them.
,10.Geosphere - ANSWER the solid part of the earth consisting of the crust and
outer mantle
11.Hydrosphere - ANSWER All the water at and near the surface of the earth,
97% of which is in oceans
12.atmosphere - ANSWER A mixture of gases that surrounds a planet or
moon.
13.Cartography - ANSWER The science of making maps
14.Asthenosphere - ANSWER Located in the outer part of mantle, made of
semi-molten, flexible rock.
15.Lithosphere - ANSWER Brittle outermost layer of the planet. Includes solid
upper mantle and crust.
16.Crust - ANSWER Outermost layer of lithosphere. Very top layer of the
earth which is also the thinnest
17.Hot Spots - ANSWER Plumes of hot magma producing places where
molten material from the mantle reaches the lithosphere.
18.Plate Tectonics - ANSWER Theory that states the Earth's lithosphere is
divided into plates, most of which are constantly moving
, 19.Tectonic Cycle - ANSWER Sum of processes that build up and break down
the lithosphere.
20.Subduction - ANSWER Oceanic plates meeting continental plates and the
ocean crust is pulled downward while the heavier plate is pulled upwards.
One plate passing under another.
21.Volcano - ANSWER Plate moving over a hot spot, heat from the rising
mantle melts the crust forming it. A vent to earth’s surface emitting ash, gas
and lava
22.Divergent Plate Boundaries - ANSWER Boundaries where oceanic plates
move apart from one another. (Conveyor belt)
23.Seafloor Spreading - ANSWER Phenomenon Where magma is pushed
upward and out from the divergent plate boundaries to form new rock.
Creates new lithosphere.
24.Moving from the earth's crust towards the earth's core, temperature
_____________ and pressure _______________. - ANSWER increases;
increases
25.Large crystal size is associated with what type of rock? - ANSWER
Intrusive igneous
26.Rocks found within the core of a mountain range formed along a
continental-continental convergent plate boundary are likely to be: -
ANSWER Metamorphic
27.processes associated with a mid-ocean ridge - ANSWER Mantle convection
