NES 103 Science Questions | Accurate & Verified
Answers to Pass Actual Exam
black holes
Ans: Created when very large stars collapse. They have a gravitational
force so strong that light cannot escape.
stars
Ans: Hot balls of plasma and gasses. There are many types , including
Supergiant, White Dwarfs, Giants and Neutrons.
Assignment Expert
nebulas
Ans: Large clouds of dust and gas where stars form.
Guru01 - Stuvia
galaxies
Ans: Consist of stars, gas and dust held together by gravity and contain
millions of stars. Ours is called the Milky Way.

lunar eclipse
©
Ans: Occurs when Earth lines up between the moon and the sun; the
moon moves into the shadow of Earth and appears dark in color. SEM
solar eclipse
Ans: Occurs when the moon lines up between Earth and the sun; the
moon covers the sun, blocking sunlight. EarthMoonSun
cycle of day and night
Ans: It takes 24 hours for the Earth to rotate on its axis.
seasonal cycle
Ans: During this cycle it takes 365 days for the Earth to revolve around
the sun.

mineral
Ans: A naturally occurring solid, inorganic substance with a crystalline
structure. ID properties include color, luster, hardness and density. EX:
talc, topaz
rock
Ans: A naturally occurring solid that can be organic or inorganic and is
composed of 1 or more minerals. Classified based on their method of
formation. There are 3 types: igneous, sedimentary and metamorphic.
igneous rocks
Assignment Expert
Ans: Rocks formed by the tectonic process that bring magma to the
earth's surface. Liquid rock cools and solidifies.
Guru01 - Stuvia
sedimentary rocks
Ans: Formed from the compaction of rock fragments that results from
weathering and erosion.
2026
metamorphic rocks
©
Ans: Rocks formed when extreme temps and pressure cause the structure
of preexisting rocks to change.
the rock cycle
Ans: Describes how rocks form and break down.
1 magna rises to the surface creating igneous rocks.
2 The rocks weather subjecting them to mechanical/chemical breakdown.
Erosion then moves that sediment to a new location. The ongoing
sediment deposit compacts creating sedimentary rocks.
3 As new layers are added, rocks and minerals are forced closer to the
earth's core where they are subject to heat and pressure, creating
metamorphic rock. These rocks eventually melt and the cycle starts over.

paleontology
Ans: The study of the history of life through fossils.
tectonic plates
Ans: The dozen or so plates that make up the surface of the Earth.
crust
Ans: The outermost layer of the earth, including tectonic plates.
mantle
Ans: The layer of earth below the crust.
Assignment Expert
core
Guru01 - Stuvia
Ans: The layer at the center of the earth. The outer part is a liquid layer
and the inner part is solid iron. The inner core creates the earth's
magnetic field.

hydrosphere
Ans: The water found on and below the earth's surface.
©
5 oceans
Ans: The Arctic, Atlantic, Indian, Pacific and Southern account for 71% of
the earth's surface and 97% of its water.
groundwater
Ans: Water stored underground. It starts on the surface with rain and
then moves through the soil. When it can go no deeper, it creates an
aquifer. An aquifer is an underground reservoir inside the rocks.
water cycle
Ans: The circulation of water throughout the earth's surface, atmosphere
and hydrosphere.
