A)volcanoes
B)Earth shrinking
C)meteorite impacts
D)continents colliding
Answer:
D)continents colliding
Explanation:
Alfred Lothar Wegener was a brilliant geophysicist and meteorologist who was famous for his research and formulation of the hypothesis of continental drift.
He hypothesized that mountains formed as a result of the collision of two drifting continents, which causes it to crumble and fold. Wegener's theory was not accepted by the scientific community until more than fifty years later.
A warm water port means your ships can project power year round. The mission of a navy is to protect shipping lanes, or you won't have any economic strength. Projecting power year round lets you protect your own trade by keeping sea lanes open (these are called sea lines of communication, or SLOCs). You protect your trade and your allies. With a navy you can control trade to other countries and mount invasions.
A flexible system of operation that uses considerably fewer resources than a traditional system is called <u>Lean operation</u>.
Lean operations is a technique of running a business by focusing on providing improved customer satisfaction while utilising as few resources as feasible. The purpose of lean operations is twofold: Creating value for customers and eliminating waste. Companies that adopt lean operations are highly focused with efficiency. Everything in a business’s activities that do not meet the ultimate objective of delivering customers value and creating profits is eliminated from the company. Hence the “lean” in lean operations. Mostly, if you implement lean operations, you want to cut all inefficiencies. Lean operations allow firms to do more with less which creates value and enhances profits.
