Earth's Systems
This system includes all living things.
BONUS: Name the living spheres in order (Smallest to Largest): Biosphere, Population, Individual, Community, Ecosystem, & Biome
Biosphere
Individual, Population, Community, Ecosystem, Biome, Biosphere
Water changing from liquid to gas.
Evaporation
Breaking rocks into smaller pieces.
Weathering
Most of Earth’s water is this type.
Saltwater
What type of energy from the Sun powers Earth’s systems?
Heat energy (or solar energy)
This system includes all water on Earth.
Name all parts of the this Cycle (4 things)
Hydrosphere
Condensation, Transpiration, Evaporation, Precipitation
Water changing from gas to liquid.
Condensation
Moving sediment from one place to another.
Erosion
What does salinity measure?
Saltiness
Warm water moving to cooler areas helps move this.
Heat
This system includes rocks and land.
Name all the layers of this sphere. (4 things)
Geosphere
Crust, Mantle, Outer Core, Inner Core
Water falling from clouds.
Precipitation
A river carries sand and rocks downstream. Is this weathering or erosion? Explain why.
Erosion, because the sediment is being moved from one place to another.
What causes ocean surface currents?
Wind
Name one way wind forms.
Change in temperature
This system includes air.
Name the layers of this sphere. (5 Layers)
Troposphere, Stratosphere, Mesosphere, Thermosphere, and Exosphere
What provides energy for the water cycle?
The Sun
Name ONE agent of weathering or erosion.
Wind, Water, Ice, Organisms
What tiny organism starts ocean food chains?
Phytoplankton
El Niño means ocean water is…
Warmer
Name TWO Earth systems that interact when plants grow.
Explain how they interact with plants.
Biosphere: Living things for it to grow
Geosphere: Soil Ground Nutrients
Hydrosphere: Watering the plant
Atmosphere: Helps with them for CO2 and them to make oxygen.
Explain how the water cycle connects at least TWO Earth systems.
Example: Water (hydrosphere) evaporates into the air (atmosphere) and falls back to land (geosphere).
Explain the difference between weathering and erosion.
Weathering = breaking
Erosion = Moving
How do oceans affect climate?
Move heat/ affect temperature
Explain how the Sun’s energy helps create wind.
The Sun heats Earth unevenly, causing warm air to rise and cool air to move in. This movement of air creates wind.
