Answer:
A. technology can be used to overcome physical barriers and boundaries
Explanation:
The ability to dam water and use of improved transportation are clear proofs of how we can overcome physical barriers and boundaries.
- Dam water is an engineering revolution by which water can be made available all year round.
- Also, damage to the ecosystem caused by excess water is circumvented.
- Roads that are pliable are of huge important in breaching geographical imitations. A good transport system can make use of this connectivity.
- Air transportation has improved the ease of travel and reduced travel time greatly.
- Both dams and good transportation are clear engineering solutions to overcome limitations of nature.
a solar eclipse, when the moons shadow comes between the sun and earth
a large area of flat unforested grassland in southeastern Europe or Siberia
<span>The angular size of the moon in our sky is almost exactly the same as the angular size of the sun in our sky. This can be seen and noticed during a full eclipse, by some remarkable coincide, the Earth's moon, from our point of view, is at the perfect distance from Earth in relation to the sun, to have almost matching sizes, allowing for the complete blocking of light when the moon and sun align.</span>
