Questions and Answers
- 1.
Which of the following is most responsible for weathering of rocks? (AZ HS Science S6:C1:PO2)
- A.
Interaction with the atmosphere
- B.
Activity of microorganisms
- C.
Release of acidic chemicals from plants
- D.
Decay of organic materials
Correct Answer
A. Interaction with the atmosphereExplanation
The interaction with the atmosphere is most responsible for weathering of rocks. This is because weathering is the process by which rocks are broken down and altered by exposure to the elements, such as air, water, and temperature changes. The atmosphere plays a significant role in weathering as it contains oxygen, moisture, and various gases that can chemically react with the minerals in rocks, causing them to break down over time. Additionally, wind and rain, which are part of the atmosphere, can physically erode rocks by carrying away small particles or by causing mechanical stress on the rock surface.Rate this question:

Which horizon is mostly rock, and why? (AZ HS Science S6:C1:PO7)
- A.
O – the organic rich layer is otherwise unaltered rock.
- B.
C – it is the bottom of the profile, immediately above unaltered rock.
- C.
E – fine particles are unaltered pieces of rock.
- D.
B – it is clay rich, and just above the layer that includes small pieces of rock.

Water is one of the major influences on the changing of landscapes by ___________. (AZ HS Science S6:C1:PO3)
- A.
Supporting erosion
- B.
"cutting" down through the surface on which it flows
- C.
Transport and deposition of sediment
- D.
All of these
Correct Answer
D. All of theseExplanation
Water is one of the major influences on the changing of landscapes because it supports erosion by wearing away rocks and soil. It also "cuts" down through the surface on which it flows, creating channels and valleys. Additionally, water plays a role in the transport and deposition of sediment, carrying particles and depositing them in new locations. Therefore, all of these factors contribute to the changing of landscapes.Rate this question:

Where two different air masses meet is called a______________. (AZ HS Science S6:C2:PO11)
- A.
Spring
- B.
Vents
- C.
Front
- D.
Drought
Correct Answer
C. FrontExplanation
When two different air masses meet, it is referred to as a "front." A front is a boundary between two air masses with different characteristics, such as temperature, humidity, and density. The collision of these air masses can lead to changes in weather conditions, such as the formation of clouds, precipitation, or changes in wind direction. Fronts are important in meteorology as they are responsible for many weather phenomena, including storms and weather patterns.Rate this question:

The amount of matter in a given space is _____________. (AZ HS Science S6:C2:PO9)
- A.
Sink
- B.
Amplitude
- C.
Density
- D.
Float
Correct Answer
C. DensityExplanation
Density refers to the amount of matter (mass) per unit volume in a given space. It is a measure of how tightly packed the particles are in a substance. Objects with high density have more mass in a given space, while objects with low density have less mass in the same space. Therefore, density is the correct answer as it accurately describes the amount of matter in a given space.Rate this question:

- 6.
Which is more dense? (AZ HS Science S6:C2:PO9)
- A.
Hot Air
- B.
Cold Air
Correct Answer
B. Cold AirExplanation
Cold air is more dense than hot air because cold air molecules are closer together and have less kinetic energy. As a result, cold air has a higher mass per unit volume compared to hot air. This is why cold air sinks while hot air rises.Rate this question:

What variable is on the X and Y axis respectively? (AZ HS Science S1:C3:PO1)
- A.
Number and dates
- B.
Months and inches of snowfall
- C.
Snow and months
- D.
Inches of snowfall and months
Correct Answer
B. Months and inches of snowfallExplanation
The correct answer is inches of snowfall and months. In a graph, the X-axis represents the independent variable, which is usually time in this case, and the Y-axis represents the dependent variable, which is the amount of snowfall measured in inches. Therefore, the variable on the X-axis is months and the variable on the Y-axis is inches of snowfall.Rate this question:

. The sun and all the objects like planets that orbit our sun is called _________________. (AZ HS Science S6:C3:PO6)
- A.
Solar system
- B.
Star is born
- C.
Small mass
- D.
Mass
Correct Answer
A. Solar systemExplanation
The correct answer is "solar system." The sun and all the objects that orbit it, including planets, moons, asteroids, and comets, make up the solar system. The term "solar" refers to the sun, and "system" refers to a group of objects that are connected or related in some way. Therefore, the term "solar system" accurately describes the collection of celestial bodies that revolve around the sun.Rate this question:

The progression of changes in the moons appearance during the month. (AZ HS Science S6:C3:PO3)
- A.
Solstice
- B.
Tides
- C.
Rotation
- D.
Phases
Correct Answer
D. PhasesExplanation
The correct answer is "Phases" because the progression of changes in the moon's appearance during the month refers to the different phases of the moon. The moon goes through a cycle of phases, starting with the new moon, then waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, third quarter, and finally waning crescent. These phases occur as a result of the moon's position in relation to the sun and Earth, causing different amounts of the moon's illuminated surface to be visible from Earth.Rate this question:

What is the 4th planet from the sun? (AZ HS Science S6:C3:PO2)
- A.
Star
- B.
Mars
- C.
Moon
- D.
Earth
Correct Answer
B. MarsExplanation
Mars is the 4th planet from the sun. It is commonly referred to as the "Red Planet" due to its reddish appearance. Mars is known for its distinct features such as the largest volcano and the deepest canyon in the solar system. It is also the planet that has been the focus of numerous space missions and exploration due to its potential for supporting life and its similarity to Earth in terms of geology and climate.Rate this question:
