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.

Question: "How can water move a rock?"

French and British Ties and Occupation: The daughter of Ferdinand and Isabella married the son and heir of the Holy Roman Emperor, Maximilian of Hapsburg. The Spanish crown duly passed to the Hapsburgs, and Spain remained in their hands until the feeble-minded Carlos II died in 1700, leaving no heir. France seized the chance to install the young grandson of Louis XIV on the Spanish throne. A rival Hapsburg claimant was supported by Austria and Britain, who saw a powerful Spanish-French alliance as a major threat. In the subsequent War of the Spanish Succession (17021713) most of the old kingdom of Aragon, including the Balearics, backed the Hapsburgs. Britain seized Gibraltarin the name of the Hapsburg claimantand retained it when the war was over. In 1708 Britain captured Menorca, and the magnificent harbor of Mahon (Mao), for the Royal Navy. England clung to it even when Bourbon forces captured Mallorca at the end of the war. Menorca changed hands between Britain, France, and Spain five more times in less than a century. Britain finally ceded the island to Spain in the year 1802, under the terms of the Treaty of Amiens. By 1805, Spain was once more aligned with France, and Spanish ships fought alongside the French against Nelson at Trafalgar. Napoleon came to distrust his Spanish ally and forcibly replaced the king of Spain with his own brother, Joseph Bonaparte. A French army marched in to subdue the country. The Spanish resisted and, aided by British troops commanded by the Duke of Wellington, drove the French out. What British historians call the Peninsular War (18081814) is known in Spain as the War of Independence. In the 19th century, practically all of Spain's possessions in the Americas broke away in the wake of the Napoleonic Wars, and the few that remained were lost at the end of the 19th century. The Balearics, further neglected, were beset with poverty and outbreaks of disease. However, toward the 20th century, things began to improve on the islands, with Mallorca reaping the rewards of successful agricultural crops and Menorca launching an export shoe industry.

Question: "How many years passed between the death of Carlos II and the start of the War of the Spanish Succession?"

Magnetism is the ability of a material to be attracted by a magnet. It also include the ability for some material to act like a magnet. No doubt youve handled refrigerator magnets. You can see some in Figure 1.28. You probably know they stick to a metal refrigerator. This is what holds your homework up. Maybe your little sisters drawings are hung on the fridge in this manner. Do magnets stick to all materials? Of course not. You have probably checked and they do not stick to other surfaces. They do not stick to wooden doors or glass windows. Wood and glass are not attracted to a magnet. Obviously, only certain materials are attracted to magnets.

Question: "What holds your homework up on a refrigerator?"

OPTIONS:
