Earths magnetic field helps protect Earth and its organisms. It protects us from harmful particles given off by the sun. Most of the particles are attracted to the north and south magnetic poles. This is where Earths magnetic field is strongest. This is also where relatively few organisms live. Another benefit of Earths magnetic field is its use for navigation. People use compasses to detect Earths magnetic north pole. Knowing this helps them tell direction. Many animals have natural 'compasses' that work just as well. Birds like the garden warbler in Figure 1.36 use Earths magnetic field. They use it to guide their annual migrations. Recent research suggests that warblers and other migrating birds have structures in their eyes. These structures let them see Earths magnetic field as a visual pattern.

Imagine a glass of your favorite drink that never became empty. Now think about what really happens. You take a drink and there is less in the glass. You keep drinking and soon it is all gone. Good thing you have more to refill your glass. What if there would never be any more of your favorite drink. What would you do? Now you know the difference between renewable and non-renewable. Its too bad that many things here on Earth will run out. This includes some of our natural resources we depend on. Things like oil will not last forever. There is a limited supply. Someday, we will run out, so then what? At current rates of use, coal will last about 300 years. Petroleum will be used up in just a few decades.

Flowing water causes sediment to move. Flowing water can erode both rocks and soil. You have already learned that materials can dissolve in water. With enough time, even rocks can be dissolved by water. This process happens really slowly. It may take over a million years to dissolve a rock. It doesnt matter how big the rock is. With enough time, flowing water can dissolve it. Moving water also has the ability to move small pieces of rock and soil. How can water move a rock? Doesnt it need energy? Of course, water gets its energy because it is moving. Moving water has kinetic energy. Things that have more energy can do more work. When water stops moving it will have no energy. It will no longer be able to move the rock and soil. When this happens the rock and soil will settle to the bottom of the calm water. Scientists call this process deposition.

(CNN) -- Deposed Honduran President Jose Manuel Zelaya will not be reinstated as head of state, an overwhelming majority of the Honduran congress voted Wednesday. In an hours-long process, 111 lawmakers voted in favor of a motion not to return Zelaya to office. A majority of 65 votes in the 128-member body was required to reject his reinstatement. Zelaya was removed from office in a military-led coup on June 28 and replaced by congressional leader Roberto Micheletti. On Wednesday, lawmakers voted one by one and addressed the chamber as they cast their vote, making for a slow process. The vote was a key part of a U.S.-brokered pact that representatives for Zelaya and Micheletti signed October 29, giving Congress the power to decide Zelaya's fate. The United States expressed disappointment Thursday over the latest rebuff to its diplomatic efforts to end the political crisis in Honduras. U.S. Assistant Secretary of State for Western Hemisphere Affairs Arturo Valenzuela continued to call on the Honduran government to allow Zelaya's return and to create a unity government in the interim period before the new president takes office next month. "We are disappointed by this decision since the United States had hoped the [Honduran] Congress would have approved his return," Valenzuela said in a conference call with journalists in Washington. "Our policy since June 28 has been consistently principled. It has condemned the coup d'etat and continued to accept President Zelaya as the democratically elected and legitimate leader of Honduras throughout this political crisis." The United States continues to call for Honduras to engage in national reconciliation and creation of a truth commission to investigate the crisis, in addition to the unity government. "The absence of democratic, constitutional order is the unacceptable status quo," a senior U.S. administration official said on the conference call, remaining anonymous under the ground rules of the call and because of the sensitivity of the situation. "The election is a step toward a day where Honduras will have an electorally legitimate government in place."
