1. Exhaustion or emptying of supply or reserve is depletion.
According to the dictionary, depletion is the loss of a principal substance in
something or reduction of amount of something when it comes to quantity,
quality, power, or value. If you’re exhausted you can say that your energy is
depleted or if there’s no more water in a reservoir you can say that your water
reserves are depleted
2. Uncleanness is impurity
This concept is often used in chemistry when you are trying
to see how pure a compound is a chemical is. You wouldn’t say however that
there is “uncleanness” in your compound but would use the word impurities since
it is the more adequate term. Impurities can affect the chemical in various
ways, from good to bad.
3. Man-made object launched by rocket into space is a
satellite
Satellites are bodies that orbit the earth in one way or another.
They can either be natural like the Moon which is a satellite, or they can be man-made
and used for various reasons such as providing internet, television, spying on
enemies, or similar things. Such satellites are launched into space with
rockets and remain there for a long time
4. Having to do with or pertaining to the sun is solar
Solar is an adjective that comes from the root “sol” which means
the sun. It is used for anything that is connected to the sun in the similar way
that lunar is used for the moon since “luna” means moon. This is why you have
things like solar flares or our system which is called the solar system and not
the sunny system.
5. Substance used to kill harmful insects or other organisms
is a pesticide
Pesticides are substances or chemicals that are used to rid
farms or plots of land from harmful organisms such as insects or bacteria or
viruses or similar. They can also be natural. For example, you can introduce an
insect that feeds on the insects that are bothering you but that doesn’t do
damage to your produce
6. To travel in a path around the earth is to orbit
When you go around the Earth, or anything for example, in a circular manner
then you are orbiting that body. For example, the moon and other satellites
orbit the Earth, but the Earth orbits the Sun. Colloquially it is also said
that any body that is within the reach of gravity is found in the Earth’s
orbit.
