Energy
What is the ability to make things move or change?
What is energy?
What is a fossil?
A clue about life from the past that is preserved in rock.
What is the job of a geologist?
A geologist studies the materials and processes that form the solid part of Earth.
What must enter your eye for you to see an object?
What is light?
What is a system?
A group of related parts that work together to perform a function.
Name three forms of energy.
Light, sound, thermal, motion, electrical, or chemical.
Name two types of sedimentary rock.
Sandstone, shale, mudstone, conglomerate, or siltstone.
Wind, solar, etc
Name two internal structures that help animals see.
Light receptors, brain, or optic nerve.
What happens to an electrical system when too many devices need more energy than the system provides?
A blackout occurs (devices stop working)
When a dolphin makes a sound, the sound energy travels through water as what?
What is a wave?
What is the lowest rock layer always?
What is the oldest?
What is sediment?
Small pieces of rock, such as silt or sand
What is the path light must travel for you to see an object?
Light source -> object -> reflects off object -> enters eye
When particles collide in a sound wave, what happens to the energy?
The energy is transferred from one particle to the next, causing them to move.
Amplitude is the height of the wave, and wavelength is the distance between wave peaks.
Explain how sedimentary rock forms
Sediment builds up in water, compacts under more sediment, and cements together over time to form rock.
Sound travels as a _____ away from a source.
What is a wave?
Nocturnal animals have high-sensitivity light receptors that work in low-light. Daytime animals have low-sensitivity receptors that work in bright light.
Add more energy sources (wind turbines, solar panels), LED Lights, add backup wires, or more wires underground.
A mother's dolphin's call has a large amplitude. What does this tell us about how the calf will hear it?
The calf will be loud enough for the calf to hear it from far away.
A canyon has different rock layers in its walls and a river at the bottom. What does this tell us about how the canyon formed?
The river eroded the rock layers over a long period of time, creating the canyon.
What is erosion?
When rock, sand, soil, is worn down and moved by water, wind, or ice.
A Tokay gecko has trouble seeing when highway lights turn on at night. Explain why using what you know about light receptors.
Explain how a wind turbine, solar panel, and device work together as a system.
The wind turbine or solar panel converts energy from the source into electrical energy. Wires transfer the electrical energy. The devices converts electrical energy into another form (light, heat, and motion).
