What is a system?
A system is a collection of parts that interact.
What are the different parts of the biosphere smallest to biggest.
Induvidual, popualtion, community, ecosystem, biome, biosphere
What are the layers of the geosphere in order?
crust, upper mantle, lower mantle, outer core, inner core.
what percent of Earth's surface is covered in water, and what type of water is there the most of?
70% and salt water.
What is the order of the layers in the atomosphere?
troposphere, stratosphere, mesosphere, thermosphere, exosphere.

The igneous rock is formed by______.
magma cooling.
What is the smallest percentage of fresh water?
lakes, rivers, and streams.
What is in air presure and what does it do.

Fill in the blank
metamorphic rock is formed by_____.
being broken down into sediment through weathering and erosion.
If a farmer drilled a hole in the ground to get water he would have drilled into what?
an aquifier
True or False.
As attuide presure increases presure increases and when attuide decreases pressure decreases.
False
Why is it important to study volcanoes?
So volcanoists can predict an eruption for people's safety and to know if you might need tp evacuate.
