earth science
First of all, clouds are never made out of water vapor. Water vapor is invisible because its molecules are too far apart to optically scatter light.
what is constructive forces
forces that build up an existing landform or create a new one.
what are magnets
magnetic substances include iron, nickel, cobalt, stainless steel, and many rare earth metals.
solid, liquid and gas
What are Some common examples of physical changes
melting, freezing, condensing, breaking, crushing, cutting, and bending.
Yes, you weigh less on the equator than at the North or South Pole, but the difference is small.
what is destructive forces
he process of breaking down of rocks and land due to forces such as gravity, wind, water and ice.
What does magnet do
it attracts things that are metal
A solid has definite volume and shape, a liquid has a definite volume but no definite shape, and a gas has neither a definite volume nor shape.
The process of burning (as opposed to evaporating) is a chemical reaction,
a chemical change.
Actually, a lot of the outside world on a sunny day is tinted blue because of the blue sky. The blue tinting of the outside world is quite striking if you know how to look for it.
what constructive and destructive forces combined together
common constructive and destructive forces include volcanoes, erosion, weathering and deposition, and many others.
what is a magnetic field
A Paramagnetic materials like calcium and aluminum are weakly attracted
When matter loses or absorbs energy
what is a physical change
is a change to a sample of matter in which some properties of the material change, but the identity of the matter does not.
The various gases in earth's atmosphere do indeed partially separate out into layers according to molecular mass, as can be seen in the figure below.
what are Constructive Earth processes are changes that add to the surface of the Earth, and some of them take millions of years to occur.
The Hawaiian Islands
where can magnets be found
in the simplest or most complex devices you use every day.
Examples of matter changes are: Melting (changing from solid to liquid).
what can Cooking food is an irreversible called
chemical change
For the sake of the argument, let's assume you could dig a wide, perfectly straight hole directly down to the center of earth and out to the other side of earth.
constructive Forces build up features on the surface of the Earth.
a natural magnet
An example of a natural magnet is the lodestone, also called magnetite.
what is Melting, evaporation and condensation are examples of
a Physical change
