ACTUAL EXAM QUESTIONS WITH CORRECT

VERIFIED ANSWERS/ RATED A+

Astronomy - ANSWER - The study of space and the relationship of objects in space.

Solar System - ANSWER - Has one star (the sun), eight planets, some dwarf planets (including Pluto), some comets, and lots of satellites (moons), asteroids, and meteors.

Sun - ANSWER - A star, a turbulent mass of incredibly hot gases exploding with repeated nuclear fusion reactions; the center of the solar system.Diameter = 864,000 miles Surface Temperature = 10,000 degrees

Sunspots - ANSWER - Cooler areas that move across the sun's surface; are associated with interruptions in radio and television transmissions.

Earth - ANSWER - The third planet from the sun.Distance from the sun = 91,000,000 - 95,000,000 miles.Diameter = 7,900 miles.

Rotation - ANSWER - Creates day and night as parts of the Earth are turned toward and then away from the sun.

Revolution - ANSWER - In orbit (path) around the sun. The Earth's axis is tilted about 23 degrees from perpendicular with the orbit around the sun. The tilting and revolving creates seasons as regions of the Earth are tilted toward the sun and away from the sun. 1 / 3

Moon - ANSWER - The satellite that revolves around Earth. Surface is covered with craters from meteorites and volcanoes.

Moon Phases - ANSWER - Different parts of the moon's surface reflect light to the Earth.

New Moon - ANSWER - When the moon is positioned between the Earth and the sun.The light from the sun is shining on the part of the moon that is facing AWAY from the Earth. That is why this phase shows a "BLACK" moon.

Full Moon - ANSWER - When the moon is on the opposite side of the Earth, so that the Earth is between the sun and the moon. The light from the sun is shining on the part of the moon that is facing the Earth. This is why this phase shows a "WHOLE" moon.

The following steps in making a cup of coffee involves a chemical change in matter - ANSWER - A burner on a propane stove is lighted to heat water.

(Review how to read the Periodic Table) Si and GE?How are they similar? - ANSWER - Most similar chemical properties

Which of the following liquids is the most acidic and will have the lowest pH? - ANSWER

c14 is an isotope of c12. Both carbon atoms have an atomic number of six. Which of the following is the main difference between these two types of carbon atom? - ANSWER - The c14 atom has 8 neutrons and c12 atom has six neutrons.

Which of the following examples best demonstrates the difference between thermal energy and temperature? - ANSWER - A cup of water at 50 degrees Cel. contains less thermal energy than a bathtub full of water at 10 degrees Cel.

Inertia (Newton's First Law) - ANSWER - A body maintains its state of rest or uniform motion unless acted upon by an outside force. Something moves only when it is pushed.

Constant Acceleration (Newton's Second Law) - ANSWER - As force is applied to an object, the object accelerates in the direction of the force. The more the mass the less the acceleration (if it's heavier, it won't move easily).

Conservation of Momentum (Newton's Third Law) - ANSWER - If two objects bump into each other, they are pushed away from each other with an equal force.

Energy - ANSWER - The ability to do work. Can be mechanical, solar, thermal, chemical, electrical, or nuclear.

water. 24 hours later the flowers will appear: - ANSWER - wilted and light blue

Which of the following statements best explains how carbon plays a central role in the functioning of biological systems? - ANSWER - Carbon combines with a large number of other elements to form a variety of useful compounds.

Certain species of acacia trees have long hollow thorns that house stinging ants. The ants feed on nectar produced by the tree and attach anything that touches the tree. The

relationship between the ants and the acacias is an example of : - ANSWER -
