Input: Heat supplies the energy that causes motion. The deeper you go into toward the Earths core, the hotter it gets. At the core it is really hot. All that heat tries to rise toward the surface. In the Mantle, the rock is partially melted and is able to move. As it is heated, the material in the mantle moves toward the surface. As the mantle material rises, it cools. When it reaches the Earths crust, it is mostly stopped. A little of the material can break through the surface, but not all. Instead, it begins to move horizontally. The mantle material moves horizontally away from a mid-ocean ridge crest. Toward the surface, the mantle material starts to cool. As it cools it sinks back down into the mantle. These areas are where deep sea trench occur. The material sinks back down to the core. The system operates like a giant conveyor belt. The motion due to heating and cooling is called convection.
"What happens when the mantle material that is near the surface starts to cool?" is "It continues going toward the surface"?

Input: Imagine you are standing in a farm field in central Illinois. The land is so flat you can see for miles and miles. On a clear day, you might see a grain silo 20 miles away. You might think to yourself, it sure is flat around here. If you drive one hundred miles to the south, the landscape changes. In southern Illinois, there are rolling hills. Why do you think this is? What could have caused these features? There are no big rivers that may have eroded and deposited this material. The ground is capable of supporting grass and trees, so wind erosion would not explain it. To answer the question, you need to go back 12,000 years. Around 12,000 years ago, a giant ice sheet covered much of the Midwest United States. Springfield, Illinois, was covered by over a mile of ice. Its hard to imagine a mile thick sheet of ice. The massive ice sheet, called a glacier, caused the features on the land you see today. Where did glaciers go? Where can you see them today? Glaciers are masses of flowing ice.
"What is the landscape in the Illinois farmlands?" is "There are rolling hills"?

Input: The Finnish government and major creditors of bankrupt shipyard Waertsilae Marine Industries Oy agreed in principle to form a new company to complete most of the troubled shipyard's backlog of 15 ships. The new company will attempt to limit the shipyard's losses, participants said. "The situation is that the bankruptcy court will get out of the shipbuilding business. Everything will be taken over by the new company," said Christian Andersson, executive vice president of Oy Waertsilae, former parent of Waertsilae Marine. Once its ownership is finalized, the new company will open talks with state-appointed receivers to buy or lease Waertsilae Marine's shipyard facilities. Subcontractors will be offered a settlement and a swift transition to new management is expected to avert an exodus of skilled workers from Waertsilae Marine's two big shipyards, government officials said. Under an accord signed yesterday, the government and Union Bank of Finland would become major shareholders in the new company, each injecting 100 million Finnish markkaa ($23.5 million). Oy Waertsilae is to contribute 200 million markkaa, most of it as subordinated debt, and take a minority stake in the new company. Customers holding contracts for Waertsilae Marine's undelivered ships are expected to subscribe most of the remaining 170 million markkaa in share capital, government officials said. Waertsilae Marine's biggest creditor is Miami-based Carnival Cruise Lines Inc. Carnival, which has three ships on order from Waertsilae Marine, presented claims for $1.5 billion damages in the bankruptcy court this week. Waertsilae Marine's bankruptcy proceedings began Tuesday in a Helsinki court.
"How much money will the new shareholders invest in the new company?" is "The are 4 shareholders. Their total investment amounts to $417M"?
