18. Click here for answer Natural Selection
Suppose a population of small lizards lives on an island of black volcanic rock. The lizards range in color form light gray to dark gray. As birds of prey feed on the lizards, they choose the light gray ones far more often than the dark gray ones. What will most likely happen to the skin color trait in this lizard population over many generations.
The dark gray lizards are better adapted for survival. Over time, numbers will most likely increase while the number of lighter lizards will decrease. The accumulation of favorable variations in a population illustrates natural selection.

19. Click here for answer Describe two ways of estimating geologic time.
Radiometric Dating – a technique based on the half-lives of radio-active isotopes that is used to determine the age or materials.
Fossils – remains or traces of prehistoric organisms that are often formed when cell structures of buried organisms are replaced by minerals.
Rock Sequencing – analyzing the order of rock strata to estimate their relative ages; Rocks lower in the order tend to be older than those near the top.

20. Click here for answer Back Which idea is NOT one of the main points
of Darwin’s theory of evolution by natural selection?
Overproduction of offspring is common in nature.
Organisms within a population must compete to survive.
Variations in population are the result of random mutations.
Organisms with favorable adaptations have a better chance of surviving to reproduce.
Darwin recognized variations in populations. However, he was unable to explain the reason for variations since he had no knowledge of mutations or other genetic processes.

21. Click here for answer Explain the theory of plate tectonics.
What are some events that change
the Earth’s surface.
C. Explain continental drift.
A the plates that make up the Earth’s surface shift, they can cause the Earth’s surface to change.
Earthquakes, volcanoes, mountain creation, and sea floor spreading are examples of events that change the Earth’s surface.
Scientists believe that 200 million years ago, Earth’s continents were joined together, forming a super-continent called Pangaea. As the tectonic plates under the continents shifted, Pangaea broke up, and the continents moved apart.

22. Click here for answer What is the Big Bang theory?
What evidence exists to support this theory?
The universe began from a small, dense collection of matter, and it has been expanding ever since.
Isotopes of hydrogen, helium, and lithium are abundant in the universe; Edwin Hubble observed universal expansion; scientists discovered that Earth receives microwave radiation from all directions.

23. Describe how force, acceleration, and mass relate in the action of kicking a soccer ball.
F = ma (Newton’s second law of motion)
Force applied to the mass results in acceleration. The greater the force applied to a given mass, the greater the acceleration will be. Therefore, if you kick the soccer ball (mass) with more force, it will speed up faster.

26. Click here for answer How does electric current flow?
Explain what makes some materials
conductors of electricity and other
materials insulators.
Electric current flows when electrons move freely.
Materials with loosely held electrons are conductors of electricity (like copper). Materials with electrons tightly bound to their atoms are insulators. (like clay and rubber)

27. Click here for answer What is Newton’s law of universal gravitation?
2. Compare your weight (the force of gravity) on the surface of the Earth to your weight on the surface of the moon.
Between any two objects in the universe there is gravity that is proportional to the masses of the objects and inversely proportional to the square of the distance between them. The more massive two objects are, the greater the force between them will be, and the farther apart they are, the less the force will be.
Your weight on the moon will be about 1/6th of your weight on Earth.

31. Click here for answer How do science and invention affect one another?
Invention uses known scientific principles to make something work better or create a new tool. Example: the discovery of electromagnetic waves led to the invention of radio, television and x-ray machines.
Using new tools (inventions) allow scientists to determine unknown scientific principles and new information. Example: The Hubble Space Telescope allows scientists to learn more about the solar system.

32. Click here for answer How do stars produce energy?
How are stars responsible for the creation of elements?
The intense heat inside a star causes the hydrogen protons to move so rapidly that they join together, or fuse. This process, fusion, is a nuclear reaction that creates energy. The star starts to glow.
Ongoing fusion of protons in starts results in many different proton combinations. Each different combination of protons is an element. After millions of years some stars explode, releasing many elements into space. Those elements may form into new stars.

33. What is the “greenhouse effect” and why is it important?
How is the theory of global warming related to this effect? What human activities might contribute to global warming?
Carbon dioxide and other gases in the atmosphere prevent the sun’s heat energy from radiating back into space from Earth.
The burning of fossil fuels increases the carbon dioxide (CO2) in the atmosphere. Because CO2 absorbs heat, the atmosphere may become warmer. Humans contribute to CO2 levels by burning gasoline and heating homes with fossil fuels.
