What system pumps blood
The Circulatory/Cardiovascular system
What is conduction.
Heat transfer through direct touch.
What is force and what is motion.
Force is what's pushing on something and motion is when something moves.
What is evaporation.
When liquid turns into a gas.
What does a food chain show
the transfer/flow of energy in an ecosystem
What make red blood cells and in what system is it.
Bone marrow in the skeletal system.
What is convection
Heat transfer through a liquid/gas.
What is gravity
A force that pulls objects to the center of the earth
What is precipitation.
Any form of water that falls from the sky.
(ex. Hail,snow,sleet, and rain)
Where does saltwater and freshwater meet.
In an estuary.
Whats the difference between the digestive system and the respiratory system.
The digestive system breaks down food into nutrients and waste and the respiratory system releases carbon dioxide and inhales oxygen.
What is radiation
Heat transfer through space or electromagnetic waves.
What causes High and Low tides.
The moons gravitational force.
What is transpiration.
When excess water evaporates through leaves.
What is the difference between a coniferous and deciduous forest.
A coniferous forest has needles and a deciduous forest has leaves.
What is the relationship between the skeletal and muscular system.
They both protect, support, and movement
What causes changes in air and water tempature
Convection
Draw me an object at rest labeling both x and y axis properly
What is percolation/infiltration.
When water from precipitation is absorbed in the ground.
grass===>grasshopper===>mouse===>snake
what happens to the population of all other organisms if mouse population decreases
What is the relationship between digestive system and respiratory system.
Both the respiratory system and digestive system give energy to the body.
Fire is all types of heat transfer, explain how.
Conduction transfers heat through direct contact, convection through the movement of fluids like air, and radiation through electromagnetic waves.
Is it true that a bigger object requires more force to move it than a smaller object
No more mass=more force. The size has nothing to do with it
What two part of the water cycle can return water to an already existing body of water
Runoff and Precipitation
what is the relationship between a decomposer and a producer?
decomposer returns nutrients to the soil for producers
