[Q]: So what is gravity? A typical definition of gravity is that it is a force. It causes an attraction between two masses. According to this definition, anything that has mass exerts a force. Any object exerts gravity on other objects. It does not matter how small it is, it has gravity. The more matter an object has, the more gravity it has. Your pencil has a tiny bit of gravity, but far too little to notice. What about a planet? It would have a lot of gravity. An objects gravity exerts a pull on other objects. Friction only occurs between objects that are touching. Gravity can act between objects that are not touching. In fact, gravity can act over very long distances. Where else can you feel gravity? <sep>How do objects interact under gravity?<sep>gravity causes an attraction between two masses
[A]: Yes

[Q]: 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. <sep>Where do sea trenches occur?<sep>Surface
[A]: No

[Q]: The Albanians first appear in the historical record in Byzantine sources of the late 11th century. At this point, they were already fully Christianized. Islam later emerged as the majority religion during the centuries of Ottoman rule, though a significant Christian minority remained. After independence (1912) from the Ottoman Empire, the Albanian republican, monarchic and later Communist regimes followed a systematic policy of separating religion from official functions and cultural life. Albania never had an official state religion either as a republic or as a kingdom. In the 20th century, the clergy of all faiths was weakened under the monarchy, and ultimately eradicated during the 1950s and 1960s, under the state policy of obliterating all organized religion from Albanian territories. The Communist regime that took control of Albania after World War II persecuted and suppressed religious observance and institutions and entirely banned religion to the point where Albania was officially declared to be the world's first atheist state. Religious freedom has returned to Albania since the regime's change in 1992. Albania joined the Organisation of the Islamic Conference in 1992, following the fall of the communist government, but will not be attending the 2014 conference due a dispute regarding the fact that its parliament never ratified the country's membership. Albanian Muslim populations (mainly secular and of the Sunni branch) are found throughout the country whereas Albanian Orthodox Christians as well as Bektashis are concentrated in the south and Roman Catholics are found in the north of the country. The first recorded Albanian Protestant was Said Toptani, who traveled around Europe, and in 1853 returned to Tirana and preached Protestantism. He was arrested and imprisoned by the Ottoman authorities in 1864. Mainline evangelical Protestants date back to the work of Congregational and later Methodist missionaries and the work of the British and Foreign Bible Society in the 19th century. The Evangelical Alliance, which is known as VUSh, was founded in 1892. Today VUSh has about 160 member congregations from different Protestant denominations. VUSh organizes marches in Tirana including one against blood feuds in 2010. Bibles are provided by the Interconfessional Bible Society of Albania. The first full Albanian Bible to be printed was the Filipaj translation printed in 1990. <sep>What religion were the majority of Albanians beforeIslam emerged as the majority religion?<sep>Christian
