How many percent of the earth's surface is covered in water?
-
70%
-
50%
-
80%
-
60%
Correct Answer
A. 70%Explanation
Approximately 70% of the Earth's surface is covered in water. This includes the oceans, seas, lakes, rivers, and other bodies of water. The remaining 30% consists of landmasses, including continents and islands. This high percentage of water coverage is a significant characteristic of our planet and has a profound impact on its climate, weather patterns, and the distribution of life forms.Rate this question:

The earth is mostly oxygen, silicon and _____
-
Quartz
-
Diamond
-
Graphite
-
Iron
Correct Answer
A. IronExplanation
The earth is mostly composed of oxygen, silicon, and iron. Iron is a common element found in the Earth's crust, making up a significant portion of the planet's composition. It is an essential element for various geological processes and is also present in the Earth's core. While quartz, diamond, and graphite are minerals found on Earth, they do not make up a significant portion of the planet's composition like iron does.Rate this question:

Earth is the only planet in the solar system with ______
-
Mountains
-
Seas
-
Clouds
-
Plate tectonics
Correct Answer
A. Plate tectonicsExplanation
Earth is the only planet in the solar system with plate tectonics. Plate tectonics refers to the movement and interaction of large sections of the Earth's lithosphere, or the outermost layer of the Earth. These plates shift and collide, causing various geological phenomena such as earthquakes, volcanic activity, and the formation of mountain ranges. No other planet in our solar system has been observed to have this dynamic process of plate tectonics, making it a unique characteristic of Earth.Rate this question:

How far does the earth's atmosphere extend into space?
-
50km
-
100km
-
10, 000km
-
100,000km
Correct Answer
A. 10, 000kmExplanation
The correct answer is 100,000km. The earth's atmosphere extends approximately 100,000km into space. This region is known as the exosphere, which is the outermost layer of the atmosphere. It gradually merges with the vacuum of space and contains very thin air molecules. This boundary is not sharply defined and can vary depending on factors such as solar activity and Earth's magnetic field.Rate this question:

What is the shape of the earth?
-
Circle
-
Sphere
-
Oblate spheroid
-
Flat
Correct Answer
A. Oblate spheroidExplanation
The shape of the Earth is an oblate spheroid. This means that it is mostly spherical, but slightly flattened at the poles and bulging at the equator. This shape is a result of the Earth's rotation, which causes the equator to experience centrifugal force, pushing material away from the axis and creating the bulge. The oblate spheroid shape has been confirmed through various scientific measurements and observations, including satellite data and measurements of gravity.Rate this question:

What creates the earth's magnetic field?
-
North and South Pole
-
The distance from the sun
-
The molten iron core
-
The distance from the moon
Correct Answer
A. The molten iron coreExplanation
The earth's magnetic field is created by the molten iron core. The core is made up of liquid iron and nickel that is constantly in motion due to the earth's rotation. This motion generates electric currents, which in turn create a magnetic field. The magnetic field extends from the core to the surface of the earth and is responsible for protecting the planet from harmful solar radiation and guiding compasses. The distance from the sun and moon do not play a direct role in creating the earth's magnetic field.Rate this question:

How long is a sidereal day?
-
24hrs
-
23hrs
-
23hrs 53mins
-
23hrs 56mins 4secs
Correct Answer
A. 23hrs 56mins 4secsExplanation
A sidereal day is the time it takes for the Earth to complete one full rotation on its axis relative to the stars. This period is approximately 23 hours, 56 minutes, and 4 seconds. It is shorter than a solar day (24 hours) because during one rotation, the Earth also moves along its orbit around the Sun. This means that it takes a little extra time for the Earth to complete a full rotation relative to a distant star.Rate this question:

Apart from the moon, how many asteroids are locked into a coorbital orbit with earth?
-
2
-
4
-
1
-
3
Correct Answer
A. 2Explanation
The question asks about the number of asteroids that are in a coorbital orbit with Earth, excluding the moon. A coorbital orbit refers to objects that share the same orbital path as another object. The answer states that there are 2 asteroids locked into a coorbital orbit with Earth, indicating that there are two asteroids that follow a similar path around the sun as Earth does.Rate this question:

The feature, furthest from the center of the earth is _____
-
Kilimanjaro
-
Everest
-
Chimborazo
-
Himalayas
Correct Answer
A. ChimborazoExplanation
Chimborazo is the correct answer because it is the highest peak in Ecuador and is located near the equator. Due to the equatorial bulge, the Earth's shape is not a perfect sphere, but rather an oblate spheroid. As a result, points near the equator are farther from the center of the Earth compared to points at higher latitudes. Since Chimborazo is located near the equator, it is further from the center of the Earth than other mountains like Kilimanjaro, Everest, or the Himalayas.Rate this question:
