Matter and Energy
The particles in this state move randomly in all directions and are farthest apart.
What is gas?
A wave that moves through matter (medium).
What is a mechanical wave?
The thin envelope of gases that surrounds the planet
What is atmosphere?
Convection currents flow in this layer of the Earth, where the heat source is from Earth's core.
What is the mantle?
The smallest unit of function and structure in living things
What are cells?
The transfer of energy by the movement of fluids.
What is a convection?
The number of times a wave repeats in a given amount of time.
What is frequency?
The force caused by the weight of a column of air pushing down on an area.
What is air pressure?
Rock formed from the cooling of molten (melted) rock.
What is igneous?
This type of organism has many cells that work together to keep them alive.
What is multicellular?
The process by which molecules at the surface of a liquid absorb enough energy to change into a gas
What is evaporation?
The thin section of the electromagnetic spectrum that human vision can perceive.
What is visible light?
This layer of the atmosphere is the lowest layer and contains weather.
What is the troposphere?
Rock that has been changed by heat and pressure.
What is metamorphic rock?
Organelle in a plant cell that uses light energy to produce food.
What is chloroplast?
The melting point of water in Celsius.
What is 0 C?
A wave transmits this from place to place.
What is energy?
Sea breezes and land breezes are local winds caused by this, which happens when warm air rises and cold air sinks.
What is convection currents?
The supercontinent that was formed before the continents drifted apart.
What is Pangea?
What is tissue?
An inward force, or pull, among the molecules in a liquid that brings the molecules on the surface closer together.
What is surface tension?
The bouncing back of a wave.
What is reflection?
The front when a warm air mass collides and rides over a cold air mass. It brings long periods of precipitation and warmer temperatures.
What is a warm front?
What is divergent boundaries?
This body system brings in oxygen and moves out carbon dioxide through the lungs.
What is the respiratory system?
