(L.8.2)
What type of reproduction requires only one parent and results in offspring that are genetically identical clones?
What is Asexual Reproduction?
This is the term for a wave bouncing off a surface, like your image in a mirror or an echo in a cave.
What is Reflection?
What moves by convection currents, and can create or destroy mountains, volcanoes, or fault zones?
What is Plate Tectonics?
What layer is always the oldest if untouched?
What is the Bottom Layer?
This is the natural process where wind or water carries away the fertile top layer of soil, often made worse by human activities like over-farming.
What is Soil Erosion?
In a Punnett square, this term describes an organism that has two different alleles for a trait, such a (Bb)
What is Heterozygous?
This property of a wave determines its "volume" in sound or "brightness" in light.
What is Amplitude?
These massive "convection currents" in this layer of the Earth are the primary engine that moves the tectonic plates.
What is the Asthenosphere? (Upper Mantle)
What fossils live for a short time and are found on a short layer?
What are Index Fossils?
What type of resources like sunlight and wind, can be replaced as fast as they are used?
What are Renewable Resources?
While genes may provide a blueprint, these factors shape a person or an animal.
What are Environmental Factors?
What wave length move perpendicular to wave motion?
What are longitudinal Waves?
This is the name for the process where one tectonic plate sinks or subducts beneath another and melts into the mantle.
What is Subduction?
What type of rock are most fossils found in?
What is an Sedimentary rock?
This occurs when rain washes away parts of soil from a highland further down. What is it?
What is Runoff?
These structures, located in the nucleus of a cell, are made of DNA and contain the genetic blueprints for an organism.
What are Chromosomes?
Because they require a medium (like air or water) to travel through, sound waves are classified as this type of wave.
What is a Mechanical Wave?
This is the name for the ring of volcanoes and earthquake sites that circle the edges of the Pacific Ocean. (Hint: This was done as homework.).
What is the Ring of Fire?
What is a trace fossil?
A. A Dinosaur Footprint.
B. A Human Tooth.
C. A Car.
A. Dinosaur Footprint
This is the name for the tiny, microscopic organisms (like bacteria and fungi) that humans must keep healthy in the soil to break down waste and recycle nutrients.
What are Decomposers?
This type of change in a DNA sequence can be neutral, harmful, or beneficial, and is a primary source of genetic variation.
What is a Mutation?
Unlike sound, these types of waves (including light and X-rays) do not need a medium to travel through. What's the type of wave?
What are Electromagnetic Waves?
This process, driven by the Sun, breaks down rocks on the surface without moving them, which is the first step in making soil.
What is Weathering?
This is the branch of science that specifically studies fossils and prehistoric life.
What is Paleontology?
This is the smallest type of soil particle; it holds water very well, but humans find it difficult to farm because it easily becomes "waterlogged."
What is Clay?
