, QUESTION 1
1.1 Define the following scientific terms:
1.1.1 Scientific method:
The scientific method is a series of steps followed by scientific investigators to
answer specific questions about the natural world. It involves making observations,
formulating a hypothesis, and conducting scientific experiments.
1.1.2 Hypothesis:
A supposition or explanation (theory) that is provisionally accepted in order to
interpret certain events or phenomena, and to provide guidance for further
investigation. A hypothesis may be proven correct or wrong, and must be capable of
refutation. If it remains un-refuted by facts, it is said to be verified or corroborated.
1.1.3 Theory:
In science, the term "theory" refers to a well-substantiated explanation of some
aspect of the natural world, based on a body of facts that have been repeatedly
confirmed through observation and experiment.
1.1.4 Lithosphere:
The lithosphere is the solid, outer part of the Earth. The lithosphere includes
the brittle upper portion of the mantle and the crust, the outermost layers of Earth’s
structure. It is bounded by the atmosphere above and the asthenosphere (another
part of the upper mantle) below.
1.1.5 Universe:
The Universe is everything we can touch, feel, sense, measure or detect. It includes
living things, planets, stars, galaxies, dust clouds, light, and even time. Before the
birth of the Universe, time, space and matter did not exist.
