Matter and the environment
Ph scale is on a scale from..
0-14
The output of a system moving in one direction acts as input that causes the system to move in the other direction. These stabilize systems and are common in nature.
Example: predator and prey populations
Negative feedback loop
inner most layer of the earth
What is inner core?
Two spheres that interact for water cycle
What is hydrosphere and atmosphere?
What makes up 78 percent of our atmosphere by mass, and is the 6th most abundant element?
Nitrogen
The highest base rating on the Ph scale would be a score of...
14
The sphere consist of all the planets living and nonliving parts of the environment.
Biosphere
When magma or molten rock surges upward to the surface pushing plates apart creating new crust as it cools happens where?
At divergent plate boundaries
The hydrologic cycle is also known as the
water cycle
Lakes and rivers are about what percent of all water on earth?
1 percent
The highest acid rating on the Ph scale would be a ....
0
This sphere encompasses all water on earth's surface
hydrosphere
Collision and seperation of tectonic plates results in what?
Nutrients that circulate endlessly throughout the environment in complex cycles are called
Biogeochemical cycles or nutrient cycles
The continuous movement of water between the atmosphere and the hydrosphere.
What is the water cycle?
List the 4 types of macromolecules
lipids, proteins, carbohydrates, nucleic acids
What is above the outer core but below the upper mantle...
lower mantle
The outer core is made up of what 2 things?
What are the 4 nutrients that cycle through all of earths spheres and organisms?
Carbon, Oxygen, Phosphorous, Nitrogen
When plates collide one of two events can happen.. what are they?
subduction- one plate sliding beneath another creating volcanoes
mountain building- when they collide and slowly lift material from both plates
Water
Erosion, the removal of soil by water,wind,ice, and gravity can lead to this type of loop
positive feedback loop
Earths surface consist of how many major tectonic plates?
15
Cellular respiration and photosynthesis are very familiar processes that many know. These systems are part of and contribute most to what cycle?
The carbon Cycle
These are polymers taht serve many funtions in organisms. They are made up of carbon, hydrogen, oxygen, nitrogen, and sometimes sulfer. Some provide support and produce tissue.
