Earth Science
What is Sedimentary rock formed out of?
When sediment is deposited out of air, wind, gravity, or water flows.
These are animals without backbones, typically insects and worms, small and slow moving, and there are around 2 million of them.
Invertebrates
What is Potassium (K) Chloride (CI) made of?
KCI is a metal and nonmetal
Potassium (K): is the metal
Chloride (CI): is the nonmetal
What tells how fast an object is moving and what direction it is moving in?
Velocity is speed and direction
What is one example of Natural Selection?
The black mice blending in with the black rocks, and the birds eating the tan mice. Over the years, there becomes larger amounts of the black mice and fewer tan mice.
What is most likely to increase the fossil process?
Rapid burial under large amounts of sediment (where calcium carbonate is). This prevents decay of the organic material.
What era did dinosaurs come to Earth?
Mesozoic (245-66 million years ago)
What is the Nervous System made up of and what role does it play?
It is made up of the brain & spinal cord. It's role is to transmit nerve impulses between parts of the body.
What measures temperature?
A Thermometer (which consists of a glass tube filled with mercury or some other liquid).
What is Artificial Selection?
Humans select them breeding of animals and plants.
Which planets are the least dense?
Jupiter, Saturn, Uranus, and Neptune
*Saturn is the least dense of them all*
What animals have Hallow Bones?
Almost all birds have hallow bones. Their hallow bones all them to fly long distances without getting worn out from carrying their own weight.
How much matter (mass) is packed into a given area.
Density
Ex: A room full of people is more dense than a room with only two people in it.
What are some inventions Thomas Edison is known for?
Phonograph, Motion picture camera, electric light bulb
Gives the cell structure "Blueprints for the cell" or the "framework"
Cytoskeleton
Do the gas planets (Jupiter, Saturn, Uranus, Neptune) have fewer or more moons than the rocky planets (Mercury, Venus, Earth, Mars)?
The gas planets have many more moons
What are 3 Geography barriers?
Oceans, lands, and mountains
What is Mass and what is it measured in?
It is measured in (kg). The mass of an object never changes. it is also the total amount of matter in an object.
Ex: Your weight on Earth and the moon is different, but your Mass stays the same.
What are the 5 conditions of a chemical change
Color
Formation of precipitate (becoming a solid)
Formation of gas
Odor change
Temperature change
The cells start out all together and then move away from one another or spread out
Diffusion
The process of organisms changing overtime do to changes in their environment
Adaptation
These are animals with a skeleton system; highly developed brain; large in size; range from birds, snakes, humans, etc; classified into 5 groups (fish, amphibians, reptiles, birds, mammals).
Vertebrates
The amount of space an object takes up.
Volume
Ex: A beaker of water reads 10 mL. A marble is then dropped into the beaker. The beaker now reads, 25 mL. Therefore, the volume of the marble is 15 mL.
What are the 3 things in the Cell Theory?
1. All living things consist of cells
2. Cell is the basic unit of life
3. Cells come from pre-existing cells
Diffusion of water across a membrane
Osmosis
