Plate Tectonics
What is the theory of plate tectonics?
The theory that the Earth's lithosphere is divided into tectonic plates that move and interact at their boundaries.
What do fossils tell us about Earth's history?
Fossils provide evidence of past life forms and the environments they lived in.
What is natural selection?
The process by which organisms better adapted to their environment tend to survive and produce more offspring.
If all colors are absorbed except red what color do we see?
Red
What would happen if I were to face two S pole ends of magnets towards each other?
They would REPEL
Name one type of plate boundary and describe it.
Convergent boundary, where two plates move toward each other. Divergent boundary, where two plates divide apart or separate from one another. Transform boundary where two plates slide past one another.
Older fossils are found where in relation to younger fossils?
Older fossils are found lower than younger fossils. Younger fossils are closer to the surface.
What is artificial selection?
The intentional breeding of organisms for desired traits by humans.
What behavior do waves have when they refract?
They bend
A wave that bounces is called?
Refelction
What geological features are commonly formed at divergent boundaries?
Mid-ocean ridges and rift valleys.
What is the significance of index fossils?
Index fossils are used to date the layers of rock in which they are found.
Give an example of a trait that has been selected for in domestic animals.
Size in dogs (e.g., breeding for smaller or larger dogs).
Describe a heterozygous genotype.
any combination of lower and upper case letters such as Tt or Rr.
What is a hotspot and give an example.
While the tectonic plates move, the hotspots themselves are thought to remain relatively fixed, leading to the formation of volcanic chains as a plate moves over a hotspot. Hawaiian islands or hotspot in Yellowstone
How do earthquakes relate to plate tectonics?
Earthquakes often occur along fault lines where tectonic plates interact.
How do paleontologists use fossils to study evolution?
They analyze changes in species over time to understand evolutionary processes.
How does genetic variation contribute to natural selection?
Genetic variation provides a pool of traits that can be selected for or against, allowing adaptation to the environment.
What is the net force if two friends were playing tub of war and one pulls 70N to the left and the other pulls 90N to the right?
90N-70N=20N
Describe the similarities and differences between lander and rovers.
They are both space technology. Landers can only land on a celestial body. Rovers can explore a celestial body. Both can collect and send data.
What is subduction?
The process where one tectonic plate moves under another and sinks into the mantle.
Rocks that form in extreme heat and pressure are?
Metamorphic rocks.
What role does mutation play in evolution?
Mutations create new genetic variations, which can lead to new traits and potentially new species over time.
What is the speed of a car that travels 150 km in 3.00 hrs? s=d/t
50 km/hr
What distance will a car traveling 65 km/hr travel in 3.0 hrs? d=s*t
195 km
