For anyone wondering all these answers are right, I got a 100 for this test. Just to verify this is for connections academy students.
agree on all
Chairflip is 100% :) thanks!
However, it would be more convenient for us if you indicate your choice at each question, e.g., an asterisk (*).
Thanks your correct 100
Thx chairflip
To answer the multiple-choice questions, here are the explanations for each:
1. Which of Earth's spheres contains mountains, valleys, and other landscapes?
To answer this question, we need to understand the different spheres of the Earth. The four main spheres are the atmosphere (the layer of gases surrounding the Earth), the biosphere (all living organisms on Earth), the geosphere (the solid part of Earth, which includes the mountains and valleys), and the hydrosphere (all the water on Earth). Among these options, the correct answer is the geosphere because it includes landforms like mountains and valleys.
2. Which of the following are examples of destructive forces?
To answer this question, we need to understand what destructive forces are. Destructive forces are natural processes that break down or erode the Earth's surface. Among the options, both ice and wind are examples of destructive forces as they can wear away rocks and reshape the landscape.
3. Earth appears to be mostly blue when viewed from space because it is mostly covered by
To answer this question, we need to know why Earth appears blue from space. Earth appears blue because it is mostly covered by water. Therefore, the correct answer is water.
4. Which of the following keeps Earth from falling into the sun?
To answer this question, we need to understand the factors that keep Earth in its orbit around the sun. The force of gravity holds Earth in its orbit around the sun. Therefore, the correct answer is its gravitational pull.
5. Which of the following causes day and night?
To answer this question, we need to understand what causes the alternation of day and night. The rotating Earth causes day and night. As the Earth turns on its axis, different parts of the planet experience daylight (day) or darkness (night).
6. One revolution of Earth around the sun takes
To answer this question, we need to know how long it takes for the Earth to complete one orbit around the sun. This period is known as a year, so the correct answer is one year.
7. Which of the following geographic locations is least affected by seasons?
To answer this question, we need to understand the concept of seasons. The equator is least affected by seasons because it receives direct sunlight throughout the year, resulting in relatively constant temperatures.
8. The phase of the moon you see depends on which of the following?
To answer this question, we need to know what factors determine the phase of the moon visible from Earth. The phase of the moon you see depends on how much of the sunlit side of the moon faces Earth.
9. Which of the following causes an eclipse?
To answer this question, we need to understand what causes an eclipse. An eclipse occurs when an object in space comes between the sun and a third object. Therefore, the correct answer is when an object in space comes between the sun and a third object.
10. Which of the following greatly contributes to the cause of tides?
To answer this question, we need to understand the factors that contribute to the occurrence of tides. The gravitational pull of the moon and the sun greatly contributes to the cause of tides. Therefore, the correct answer is differences in how much the moon and the sun pull on different parts of Earth.
Now, let's move on to the true/false questions.
11. For a solar eclipse to occur, the sun must be positioned between Earth and the moon.
This statement is false. For a solar eclipse to occur, the moon must be positioned between the sun and Earth.
12. The force of gravity between two objects decreases as the distance between the two objects increases.
This statement is true. The force of gravity between two objects decreases as the distance between them increases.
