This level of the atmosphere is very hot because it absorbs radiation from the sun.
What is thermosphere?
100
This process curves the actual path of wind toward the poles.
What is the Coriolis effect?
100
This characteristic of a living thing in a frog is described by fertilized eggs, tadpoles, growing legs, and then living on land.
What is grow and develop?
100
This is the process where molecules spread out by moving from an area where there is a high concentration of molecules to an area of low concentration.
What is diffusion?
100
This is an organism that captures the energy in sunlight to make it's own food.
What is a photoautotroph?
200
This level of the atmosphere is very cold because it contains very low quantities of gases, mainly hydrogen and helium.
What is the exosphere?
200
This instrument is used to measure wind speed.
What is an anemometer?
200
These are two characteristics of living things that a unicellular organism, such as a paramecium, posses.
What are reproduce and being made of a cell?
200
This is the diffusion of water through a selectively permeable membrane.
What is osmosis?
200
This is a green pigment that captures the energy in sunlight and gives plants their green color.
What is chlorophyll?
300
This process describes how liquid water on Earth's surface reaches the atmosphere as water vapor.
What is evaporation?
300
This pressure system develops when warm, moist air rises from the Earth's surface.
What is a low-pressure system?
300
These types of proteins help to speed up the chemical processes in cells.
What are enzymes?
300
This describes the movement of water molecules in osmosis.
What is from areas of less solute to areas of more solute?
300
This organism gets it's energy by consuming other organisms.
What is a heterotroph?
400
This is the process where liquid water in the atmosphere returns to the Earth's surface.
What is precipitation?
400
This is the long-term pattern of weather that occurs in an area over many years.
What is climate?
400
These are the three functions of a cell membrane.
What are controls what enters and leaves the cell, holding the cell together, and giving it shape?
400
This is the term that is used to explain why some molecules can pass through the cell membrane and other molecules can't.
What is selectively permeable?
400
These are the products of photosynthesis.
What are glucose and oxygen?
500
This process melts snow and ice at the top of a mountain creating runoff that forms small streams that eventually combine to form rivers that flow into lakes and oceans and then evaporates to form rain and snow.
What is the water cycle?
500
This climate zone has relatively high, constant temperatures all year long because the sun shines directly overhear.
What is the tropical zone?
500
This is what causes an animal cell to burst when water is added to it and a plant cell will not.
What is a plant cell has a cell wall?
500
This is the term used to describe substances that are dissolved in water.
What is solute?
500
These are what the products of photosynthesis are converted into.
What are wood, carbohydrates, lipids, amino acids to build proteins, and some sugar is stored for future use as starch?
