- Question
How fast do satellites orbit the earth?
Options- A. 28,000 kmph
- B. 26,000 kmph
- C. 17,500 kmph
- D. 22,500 kmph
- Correct Answer
- 28,000 kmph
ExplanationSatellites orbit the earth at a speed of 28,000 kmph.
Satellites that are further away actually travel slower. The International Space Station has a Low Earth Orbit, about 400 kilometers (250 miles) above the earth's surface. Objects orbiting at that altitude travel about 28,000 kilometers per hour (17,500 miles per hour).

Correct Answer: rock color
Explanation:
Except Rock color, all other Graded bedding, Ripple marks and Mud cracks are sedimentary structures.
Correct Answer: Cosmology
Explanation:
Cosmology is the scientific study of the large scale properties of the universe as a whole. It endeavors to use the scientific method to understand the origin, evolution and ultimate fate of the entire Universe.
Depending on the outcome of the observations, the theories will need to be abandoned, revised or extended to accommodate the data. The prevailing theory about the origin and evolution of our Universe is the so-called Big Bang theory.
Correct Answer: humidity
Correct Answer: Tea
Explanation:
Tea crop is known as Green Gold.
Correct Answer: Exponential growth
Explanation:
An ideal habitat with unlimited resources is associated with Exponential growth.
Correct Answer: Excitement of an electron of chlorophyll photon of light
Explanation:
The first step in Photosynthesis is Excitement of an electron of chlorophyll photon of light.
Correct Answer: About 150 - 200 species of plant, insect, bird and mammal become extinct every day or 24 hrs This is not an accurate but an estimation by UN Convention on Biological Diversity and Global Extinction Rates It is also said that current extinctions were 'up to 100 times higher than the background rate'
Correct Answer: Carbondioxide
Explanation:
72% of the totally emitted greenhouse gases is carbon dioxide.
Hence, Carbon dioxide (Co2) is predominantly responsible for Global warming.
Correct Answer: Stratification
Explanation:
Stratification as actually the settling down of sediments with different properties to form layers/strata over years. Stratification especially occurs on the bed of water bodies such as oceans.
Stratified sedimentary rocks are used to study the ecological conditions over previous years/eras.
The other choices like Windstorms, Glacial Ice and Stream water are mediums which sediments are transported.
Correct Answer: Arachnids
