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.
Answer:
Explanation:
Accretion occurs as mantle is added to the growing edges of a plate, associated with seafloor spreading. This hot added material cools down by conduction and convection of heat. ... Mantle convection causes tectonic plates to move around the Earth's surface.
C is the answer. Hope this helps.
