1.
The length of an Earth day is determined by the time required for approximately one (Standard 1.1a):
Correct Answer
A. Earth rotation
Explanation
The length of an Earth day is determined by the time required for Earth rotation. This refers to the time it takes for the Earth to complete one full rotation on its axis. This rotation is what causes day and night on Earth. As the Earth rotates, different parts of the planet are exposed to the Sun's light, creating the cycle of day and night that we experience. Therefore, the length of an Earth day is directly linked to the time it takes for the Earth to complete one rotation.
2.
The diagram below represents a simple geocentric model. Which object is represented by the letter X (Standard 1.1a)?
Correct Answer
A. Earth
Explanation
The diagram represents a geocentric model, which means that it portrays the Earth as the center of the universe. The object represented by the letter X in this model would therefore be the Earth itself.
3.
Which statement provides the best evidence that Earth revolves around the sun (Standard 2.1u)?
Correct Answer
D. The seasons of spring, summer, fall, and winter repeat in a pattern
Explanation
The statement that the seasons of spring, summer, fall, and winter repeat in a pattern provides the best evidence that Earth revolves around the sun. This is because the changing seasons are a result of the Earth's axial tilt as it orbits the sun. As the Earth revolves around the sun, different parts of the planet receive varying amounts of sunlight, leading to the changes in temperature and weather that we experience as the seasons. This pattern of seasonal change is a direct result of Earth's revolution around the sun.
4.
The apparent daily path of the Sun changes with the seasons because (Standard 1.1f):
Correct Answer
A. Earth’s axis is tilted
Explanation
The apparent daily path of the Sun changes with the seasons because Earth's axis is tilted. This tilt causes the angle at which sunlight hits different parts of the Earth to change throughout the year, resulting in different lengths of daylight and different temperatures in different seasons.
5.
Base your answers to this question on the diagram below, which shows the tilt of Earth on its axis in relation to the Sun on one particular day. Points A through E are locations on Earth’s surface. Point D is located in New York State. The dashed line represents Earth’s axis. This question may require the Earth Science Reference Tables (Standard 1.1h).On this day, which location has the greatest number of hours of daylight?
Correct Answer
A. E
6.
Ocean currents influence temperature by (Standard 2.1i):
Correct Answer
C. Heating or cooling the air
Explanation
Ocean currents influence temperature by heating or cooling the air. This is because ocean currents transport warm or cold water from one region to another, which in turn affects the temperature of the air above it. Warm ocean currents can increase the temperature of the air, leading to warmer climates in nearby coastal areas. On the other hand, cold ocean currents can cool the air, resulting in cooler temperatures in adjacent regions. Therefore, ocean currents play a significant role in regulating the temperature of the surrounding atmosphere.
7.
Which changes can be expected to occur at 45° N over the next 30 days? This question may require the Earth Science Reference Tables (Standard 2.2a)
Correct Answer
D. The duration of insolation will increase and the temperature will increase.
Explanation
At 45° N latitude, the duration of insolation (the amount of time the Earth is exposed to sunlight) will increase over the next 30 days due to the tilt of the Earth's axis. As we approach the summer solstice, the days will become longer, resulting in more sunlight. Additionally, the temperature will increase as the increased duration of insolation leads to more heat being absorbed by the Earth's surface. Therefore, the correct answer is that the duration of insolation will increase and the temperature will increase.
8.
Which of these characteristics identify an Earth surface that is likely to be the best absorber of insolation?
Correct Answer
D. Dark colored and rough
Explanation
A surface that is dark colored and rough is likely to be the best absorber of insolation. Dark colors absorb more light and heat compared to light colors, and a rough surface has more surface area for the energy to be absorbed. Therefore, a combination of dark color and rough texture allows for maximum absorption of insolation.
9.
