Organisms
What do internal and external structures of organisms function to support?
Growth, survival, and reproduction.
What might a paleontologist conclude if they discovered ocean animal fossils on a highland mountain?
The area may have once been under the ocean.
Name a form of energy that is considered renewable.
Wind, Solar, or Water
Sound, light, heat, and moving objects are all categorized as what?
Energy.
What is the definition of a wave in terms of motion and energy?
Regular patterns of motion that transfer energy.
What is the primary function of a fish's gills?
To take in oxygen from the water.
What inference can be made about a species if its fossils appear in old rock layers but are missing from all subsequent layers?
The species is extinct.
How does the use of gasoline or coal specifically affect the Earth's atmosphere?
It increases carbon levels in the air.
How is the energy of an object affected as its speed increases?
It possesses more energy.
What is the term for the height of a wave from its rise to its crest?
Amplitude.
What information can fossils from long ago provide about ancient life?
The type of organisms that lived long ago.
If you found a fossil of a seashell at the very top of a tall, dry mountain, what would that tell you about what the land used to look like long ago?
It tells us that the mountain was once underwater or part of the ocean floor.
From what general source are all energy and fuels used by humans derived?
Natural sources.
When two bowling balls roll into each other and crash, what are two things you can see or hear that prove energy was used in the collision?
You can hear a loud "crash" sound, and you can see the balls change direction or bounce off each other.
What is the term for the spacing between two wave crests?
Wavelength.
Which parts of an organism, such as a shell or bone, are capable of becoming a fossil?
Hard parts.
By what natural process can wind change the shape of rocks and landforms over time?
Weathering.
What is the origin of fossil fuels?
Ancient organic material.
What energy conversion takes place inside a solar oven?
Light energy to heat energy.
Why can we see the light from distant stars in space, but we can never hear the sound of a "space explosion"?
Light waves can travel through empty space, but sound waves need matter (like air or water) to travel, and there is no air in space.
If a specific bird fossil is found in older rock layers but is absent from newer layers and the modern world, what can be inferred about that species?
The bird species is extinct.
Imagine a river flowing through a flat field for thousands of years. What are two ways that moving water will change the shape of the land?
The river can carve out a deep canyon or valley, and it can wash away soil and rocks (erosion).
List several sources that can be used to generate renewable energy.
Water, wind, the sun, and certain plants like corn.
What specific type of energy does a ball possess while it is rolling down a hill?
Kinetic energy.
In terms of wave properties, what characterizes a loud sound?
High amplitude.
