Which Earth process breaks down?
What is weathering?
What state of matter can melt?
What is soild?
What item can close a open circuit
What is a metal nail?
What vertebrate has gills?
What is a fish?
What part of the cell contrels the whole cell
What is the nucleus?
How do earthquakes happen?
What are the three primary states of matter on Earth?
The three main states are Solid, Liquid, and Gas.
What are the two poles of a magnet?
Every magnet has a North pole and a South pole. Magnetic forces are strongest at these poles.
What is a Vertebrate?
An animal that has a backbone (or spinal column). These animals usually have a complex skeleton inside their bodies.
What is a cell?
The cell is the smallest unit of life. Every living thing, from a giant whale to a tiny blade of grass, is made of cells.
What is the difference between Weathering and Erosion?
The process of breaking down rocks, soils, and minerals and The process of transporting those broken-down materials from one location to another.
What determines whether a substance is a solid, liquid, or gas?
It depends on the energy (temperature) and pressure.
What is a magnetic field?
It is the invisible region around a magnet where its magnetic force can be felt by other magnets or magnetic materials.
What is an Invertebrate
An animal that does not have a backbone. Instead of a skeleton inside, some have a hard outer shell (exoskeleton), and some are just soft all the way through.
How is a plant cell different from an animal cell?
Plant cells have two special things that animal cells don't
Is weathering constructive or destructive?
destructive process.
What is the process of a solid turning directly into a gas called?
This is called Sublimation.
What is electricity?
It is the flow of electrons (tiny particles with a negative charge) through a conductor, like a metal wire.
Which group has fur or hair and feeds milk to its babies?
Mammals
What is the "jelly" inside the cell called?
Cytoplasm.
Explain how a delta is formed.
What is a delta is formed by the destructive process of sedimentation?
What is "Evaporation" and how does it differ from "Boiling"?
Both turn liquid into gas, but evaporation happens only at the surface of a liquid and can occur at any temperature.
If you have a plain iron nail and a permanent magnet, how can you turn that nail into a temporary magnet without using any electricity or glue? And once it's a magnet, how do you "turn it off"?
You stroke the nail with the magnet in the same direction over and over. This lines up all the tiny "mini-magnets"
Most animals on Earth are vertebrates.
False! About 97% of all animal species on Earth are actually invertebrates (mostly insects).
If you look at a piece of wooden furniture, like a desk, is it made of cells?
Yes! Even though the wood isn't "alive" anymore, it came from a tree, which is a living thing made of plant cells. You can still see the old cell walls under a microscope!
