Lesson 4: MODEL AND SYSTEM Flashcards
(45 cards)
It is a set of interconnected components organized so that they function as a whole. It includes biotic (living) and abiotic (non-living) components that interact through energy flows and nutrient cycles.
system in the context of environmental science
often exchange energy and/or matter beyond their defined boundary.
• Systems
What are the three kinds of properties in a system?
• ELEMENT
•ATTRIBUTES
• RELATIONSHIPS
It is a system parts, including atoms, molecules, and larger matter bodies like sand grains, rain drops, plants, and animals, are essential components of a system.
• ELEMENTS
What is the characteristics of the elements that may be perceived and measured. For example: quantity, size, color, volume, temperature and mass.
• ATTRIBUTES
What is the associations that occur between element and attributes. These associations are base on cause and effects.
• RELATIONSHIPS
What are the 7 types of systems?
• OPEN SYSTEMS
• CLOSED SYSTEMS
• ISOLATED SYSTEMS
• MORPHOLOGICAL SYSTEM
• CASCADING SYSTEM
• PROCESS-RESPONSE SYSTEM
• CONTROL SYSTEM
A system that transfers both matter and energy can cross it’s boundary to the surrounding environment. Most ecosystems are example of open systems.
• OPEN SYSTEMS
A system that transfer energy, not matter, across its boundary to the surrounding environment. Our planet is often viewed as a closed system.
• CLOSED SYSTEMS
- A system that has no interactions beyond it’s boundary layer.
-Many controlled laboratory experiments are this type of system.
• ISOLATED SYSTEMS
A system where we understand the relationships between elements and their attributes in a vague sense based only on measured features and correlations.
• MORPHOLOGICAL SYSTEM
A system where we are primarily interested in the flow of energy and/or matter from one element to another and understand the processes that cause this movement.
• CASCADING SYSTEM
A system that integrates the characteristics of both morphological and cascading systems.
• PROCESS-RESPONSE SYSTEM
A system that can be intelligently manipulated by the actions of humans.
• CONTROL SYSTEM
a system that models relationships and interactions between the various biotic and abiotic components making up a community of organisms and their surrounding physical environment.
ECOSYSTEM
The feedback loops in an ecosystem are the dynamics that regulate its state by observing the impact of changes in one part on another and how this effect feeds back to the source.
• ECOSYSTEM FEEDBACK
A circular chain of effects opposes change, keeping things the same. When a system’s first part changes too much, other parts reverse the change in the first part, preventing system change.
• NEGATIVE FEEDBACK
What are the 4 main processes involved in the water cycle?
evaporation,
condensation,
precipitation,
And runoff.
is the process by which water changes from a liquid to a gas or vapor state.
Evaporation
What are the 4 factors influence the rate of evaporation?
temperature,
humidity,
wind speed,
and surface area of the water body.
when water vapor in the atmosphere cools and changes back into liquid form.
Condensation
It occurs when water droplets or ice crystals in clouds become too heavy to remain suspended and fall to the Earth’s surface. Precipitation can be rain, snow, sleet, or hail.
Precipitation
is water stored beneath the Earth’s surface in soil and rock formations.
Groundwater
It refers to the movement of water over the Earth’s surface. It occurs when the ground is saturated, and excess water cannot infiltrate into the soil.
Runoff
