Sciences 2025–2026 – Complete Practice
Questions and Detailed Answers
Scientific Method - Correct answer- An emperical
method of procedure that has characterized
natural science since the 17th century, consisting
in systematic observation, measurement, and
experiment, and the formulation, testing, and
modification of hypotheses.
- Acceptable experimentation techniques to ensure
results are not skewed
- Objectivity needed for valid results
- Peer review
- Experiments must be performed and recorded in
a way that it can be reproduced to verify answers
The Steps of the Scientific Method - Correct
answer- 1. Define the problem
2. Research or collect background data
3. Formulate a hypothesis or an educated guess

5. Conduct experiments or tests
6. Analyze the results of the test
7. Draw conclusions
Regression Analysis - Correct answer- In statistical
modeling, regression analysis is a set of statistical
processes for estimating the relationships between
a dependent variable and one or more independent
variables.
Sedimentary Rocks - Correct answer- Sedimentary
rocks are types of rock that are formed by the
accumulation or deposition of small particles and
subsequent cementation of mineral or organic
particles on the floor of oceans or other bodies of
water at the Earth's surface
- Erosion and weathering include the effects of
wind and rain, which slowly break down large
rocks into sediments, such as sand or mud.
Precipitation and lithification are processes that
build new rocks or minerals.
- Precipitation is the formation of rocks and
minerals from chemicals that precipitate from

water. For example, as a lake dries up over many
thousands of years, it leaves behind mineral
deposits.
- Lithification is the process by which clay, sand,
and other sediments on the bottom of the ocean or
other bodies of water are slowly compacted into
rocks from the weight of overlying sediments.
Igneous rock - Correct answer- Igneous rocks form
when magma (molten rock) cools and crystallizes,
either at volcanoes on the surface of the Earth or
while the melted rock is still inside the crust. All
magma develops underground, in the lower crust
or upper mantle, because of the intense heat
there.
Metamorphic rock - Correct answer- A type of rock
that forms from an existing rock that is changed
by heat, pressure, or chemical reactions.
The Rock Cycle - Correct answer- There are three
main types of rocks: sedimentary, igneous, and
metamorphic. Each of these rocks are formed by
physical changes—such as melting, cooling,

eroding, compacting, or deforming—that are part
of the rock cycle.
Plate Tectonics - Correct answer- Plate tectonics is
a scientific theory that explains how major
landforms are created as a result of Earth's
subterranean movements.
Earth's outermost layer, or lithosphere—made up
of the crust and upper mantle—is broken into
large rocky plates. These plates lie on top of a
partially molten layer of rock called the
asthenosphere. Due to the convection of the
asthenosphere and lithosphere, the plates move
relative to each other at different rates, from two to
15 centimeters (one to six inches) per year. This
interaction of tectonic plates is responsible for
many different geological formations such as the
Himalaya mountain range in Asia, the East African
Rift, and the San Andreas Fault in California,
United States.
- Alfred Wegener published two articles about a
concept called continental drift. He suggested that
200 million years ago, a supercontinent he called
Pangaea began to break into pieces, its parts
