100
The process by which the molecules in liquid water speed up due to energy from the sun, and are changed into water vapor
What is EVAPORATION
100
A force that acts the same on all objects no matter what the mass or volume
What is GRAVITY
100
A geographic region characterized by similar weather, temperature, rainfall, landforms, plants, and animals
What is a BIOME
100
Changes in matter such as freezing, melting or boiling
What is a PHYSICAL CHANGE
100
An organism that carries out all the essential functions of life within a single cell. These functions are transport of food and waste products into and out of the organism, reproduction, and food consumption.
What is a SINGLE CELL ORGANISM
200
The process where water vapor cools high in the atmosphere and forms small droplets which make up clouds
What is CONDENSATION
200
The factor that affects how fast an object will fall when it is acted upon by only the force of gravity
What is HEIGHT
200
The coldest and farthest north region, characterized by permafrost, some shrubs, wild-flowers, mosses and berries without any trees
What is TUNDRA
200
Changes in matter such as a color change, formation of a solid or burning (combustion)
What is a CHEMICAL CHANGE
200
A characteristic that shows up any time it is present in an organism
What is a DOMINANT TRAIT
300
The wind system that moves air masses from west to east across North America
What is the Prevailing Westerlies
300
Any change in speed or direction of a moving object
What is ACCELERATION
300
A cold weather forest with lots of snow, and evergreen trees. Winter is long and cold, and the growing season is warm and short.
What is TAIGA
300
The process where energy flows from warm to cold in a gas or a liquid
What is CONVECTION
300
An organism that carries out all the essential functions of life using a system of related organs. These functions are transport of food and waste products into and out of the organism, reproduction, and food consumption
What is a MULTICELLULAR ORGANISM
400
The process where cold dense water sinks to the ocean bottom and the poles, and travels across the ocean until it warms at the equator and becomes a surface current
What is THERMOHALINE CIRCULATION
400
A kind of friction that will slow objects down that are moving through the air
What is AIR RESISTANCE
400
A forest with four distinct seasons, and a long warm growing season. There is much biodiversity in this forest.
What is a DECIDUOUS FOREST
400
The physical and chemical properties of everything that exist are determined by the objects composition
What are atoms and molecules
400
Offspring have many of the same traits as their parents or grandparents
What is INHERITANCE
500
The area above the equator where the air is rising straight up and there are no winds
What is the DOLDRUMS
500
A force that can be rolling, sliding or fluid
What is FRICTION
500
This biome is essential to life on this planet. It has a great diversity of aquatic plants and animals, and supplies the drinking water for the entire world.
What is FRESHWATER BIOME
500
Anything that has mass and takes up space
What is MATTER
500
The directions that determine what traits an offspring will inherit from his or her parents
What is DNA
