Correct Answer
A. True
Explanation
Altitude refers to the vertical distance or height above the Earth's surface. It is a measure of how high an object or location is in relation to sea level or ground level. Therefore, the statement "Altitude is the height above Earth's surface" is correct.
11.
Weather is the condtion of the ____________ at a particular time.
Correct Answer
C. TropospHere
Explanation
The correct answer is troposphere. The question is asking for the condition of something at a particular time, and the options provided are land breeze, stratosphere, troposphere, and thermosphere. Out of these options, the troposphere is the layer of the Earth's atmosphere closest to the surface, where weather occurs. Therefore, the correct answer is troposphere.
12.
Of all these choices,which does not affect air pressure?
Correct Answer
D. Mountains
Explanation
Mountains do not directly affect air pressure. Air pressure is primarily influenced by factors such as volume, temperature, and the amount of water vapor in the air. Mountains, on the other hand, can influence local weather patterns and wind flow, but they do not directly impact air pressure.
13.
A anemometer is a tool that measures wind speed
Correct Answer
A. True
Explanation
An anemometer is a scientific instrument used to measure wind speed. It typically consists of multiple cups or blades that rotate when exposed to wind, and the rotation speed is directly proportional to the wind speed. By measuring the rotation speed, an anemometer can provide an accurate measurement of wind speed. Therefore, the statement "A anemometer is a tool that measures wind speed" is true.
14.
Warm air is _________ dense than cold air.
Correct Answer
B. Less
Explanation
Warm air is less dense than cold air because as air molecules heat up, they gain energy and move faster, causing them to spread out and take up more space. This increase in volume leads to a decrease in density. In contrast, cold air has slower-moving molecules, which allows them to pack closer together, resulting in higher density. Therefore, warm air is less dense than cold air.
15.
The Coriolis effect describes the change in the direction of something on or above Earth's surface because of Earth's _______________.
Correct Answer
C. Rotation
Explanation
The Coriolis effect is caused by the rotation of the Earth. As the Earth rotates, objects moving on or above its surface appear to be deflected from their straight path. This is due to the difference in velocity between different latitudes caused by the rotation. The Coriolis effect is responsible for the rotation of large-scale weather systems, such as cyclones and anticyclones, and also affects the direction of ocean currents.
16.
Sunlight strikes with the most vertical angle at or near the _____________.
Correct Answer
C. Equator
Explanation
Sunlight strikes with the most vertical angle at or near the equator because the equator is the imaginary line that divides the Earth into the Northern and Southern Hemispheres. Due to the Earth's tilt on its axis, the equator receives direct sunlight throughout the year, resulting in a more vertical angle of sunlight. This is why the equator experiences a relatively consistent climate and has a higher average temperature compared to other regions.
17.
An area near the ____________ receive less energy from sunlight.
Correct Answer
D. Poles
Explanation
The poles receive less energy from sunlight because they are located at the Earth's extreme latitudes. Due to the curvature of the Earth, sunlight reaches the poles at a lower angle, resulting in the sunlight being spread out over a larger area. This leads to less energy being received per unit area compared to areas closer to the equator. Additionally, the poles experience long periods of darkness during certain times of the year, further reducing the amount of sunlight they receive.
18.
The solar energy that reaches a planet is called.
Correct Answer
A. Insolation
Explanation
Insolation refers to the solar energy that reaches a planet. It is the amount of solar radiation that is received per unit area on the surface of the planet. Insolation is an important factor in determining the climate and temperature of a planet, as it is responsible for heating the atmosphere and the surface.
19.
If it is 95.5 degrees at the Equator,what would the temperature be if it were 10 times that in New York?
Correct Answer
B. 955.0
Explanation
If the temperature at the Equator is 95.5 degrees, and we want to find the temperature that is 10 times that in New York, we can simply multiply 95.5 by 10. This gives us a temperature of 955.0 degrees in New York.
20.
The equator receives more ________________ from the sun.
Correct Answer
A. Direct rays
Explanation
The equator receives more direct rays from the sun because it is located closest to the sun's rays. The equator is positioned at 0 degrees latitude and is directly in line with the sun, resulting in the sun's rays hitting the equator at a more direct angle compared to other parts of the world. This direct exposure to the sun's rays leads to higher temperatures and more intense sunlight at the equator.
21.
Air always flows from areas of _______________ to areas of ___________________.
Correct Answer
A. High air pressure,low air pressure
Explanation
Air always flows from areas of high air pressure to areas of low air pressure. This is because air moves from areas of higher density to areas of lower density. High air pressure indicates that there is a greater amount of air molecules in a given area, while low air pressure indicates that there are fewer air molecules in a given area. Therefore, air flows from areas of high air pressure to areas of low air pressure in order to equalize the pressure.
