-Gasoline is a fossil fuel. Cars use this fuel to run.
-The water cycle keeps lakes, rivers, and other water sources
from drying up.
-When water vapor cool, it condenses into water droplets.
-All rocks are made from minerals. They are the building blocks
of rocks.
-A fossil is the remains of a plant or animal that lived long
ago.
-Water,air,and soil are all natural resources.
-Water that is held in the soil and rocks underneath the ground
is called groundwater.
-Over a long period of time hardened tree sap may become
amber.
-We use our resources wisely when we conserve.
-When harmful materials get into the water, air, or land,
pollution occurs
-Igneous rocks, like granite, are made when melted rock cools and
hardens. Sedimentary rocks are formed in layers. Metamorphic rock is
when a rock changes form.
-There are three layers of soil: topsoil, subsoil, and solid
rock. The topsoil is good for growing crops because it has lots of
humus, it can hold water, and it has lots of minerals.
-Fossil fuels like oil and coal are nonrenewable resources
because it take millions of years to make them.
-Since sedimentary rocks are made from layers of deposits; they
are the best rocks to find fossil.
-The elephant is a modern relative of the woolly mammoth, just as
the cat is a relative of the tiger,
-An aqueduct is a structure that can bring water to a dry
place.
_Ages ago people use limestone (sedimentary rock) for grave
markers, but over the years they wore away. Today granite is used
because it is an igneous rock and it will last a lot longer. Many
building are using granite on the face of the building for the same
reason.
-The water cycle begins with evaporation which pulls the water
into the sky as a gas. The cloud forms and the gas condenses forming
water droplets. When the cloud gets too heavy with water droplets the
condensations falls to the ground a precipitation. This continues
over and over,but if there is pollution in the water then the water
can not evaporate and will affect the water cycle.
-Conserving our natural resources is important. We can do this by
Reduce- using fewer things and fewer resources. Reuse-keep using the
same thing and that uses fewer resources. Recycle-resources are used
again which means new resources do not have to be used.
-Beaches have been polluted by oil spills. The sand can act as a
filter and trap the oil. The oil is removed from the sand by sifting
through the sand over and over until all of the oil is removed.
