Which sphere (hydrosphere, atmosphere, biosphere, geosphere) is connected to all the others?
biosphere
How do the atmosphere and hydrosphere work together?
to allow the water cycle to constantly provide fresh water for Earth
Give an example of a connection between Earth's systems? between hydrosphere and biosphere or between atmosphere and biosphere etc.
soil, rock
abiotic
What is an organized group of related parts that interact to form a whole is?
a system
Which of these is not a characteristic of all living things?
A they respond to changes in the environment
B they maintain stable internal conditions (homeostasis)
C they are made up of more than one cell
C they are made up of more than one cell
Give an example of a complex system verses a simple system.
Complex systems have more levels of organization that simple systems have.
grass, insects
biotic
How is the biosphere organized?
groups of individuals make up populations and groups of populations make up communities
Give an example that shows how the hydrosphere and the biosphere are connected.
water in the soil could enter the roots of a plant

minerals, air
abiotic
Describe homeostasis.
homeostasis - regulation and maintenance of constant internal conditions in an organism.
On a construction site, a worker moves some debris and a bulldozer moves a different pile of debris. Which of these best explains how the worker and the bulldozer are alike?
A. Their physical properties are similar.
B. They are both systems that are performing similar functions.
C. They both use the same kind of fuel to provide them with energy.
D. They have control centers that made from the same components.
B. They are both systems that are performing similar functions.
Give an example of a model and why models help scientists.
ex: model of a dam and simulations could help scientists study the stability of the dam before spending money to build a potentially faulty one
seabirds, trees
biotic
Why is it homeostasis important to living things?
maintaining homeostasis is needed to grow, work and survive
