[Q]: (OPRAH.com) -- Chris Rock is an Emmy-winning comedian, devoted husband and loving father --but it's time to get to know a new side of this funnyman. Meet Chris Rock, hair expert. It's a detour he took after an innocent carpool ride left Rock with an idea he just couldn't shake. "I was with my daughter one day, and we're in the car and she's with one of her friends in the back seat, a little white friend," he says. "She was just kind of raving about her friend's hair a little too much for my comfort [saying]: 'You've got great hair. Oh, your hair's so good.'" Not wanting to make her comments a big deal, Rock says he tried to play his them off. "[I said]: "Oh, baby, your hair's beautiful. Come on,'" he says. "If I would have really reacted, then she would have a complex about her hair." Still, Rock couldn't let it go. "It sparked something in me," he says. Oprah.com: Oprah's hair throughout the years! What Rock discovered is a $9 billion industry that affects the daily activities, wallets, self-esteem -- and even the sex lives -- of black women. Because women spend so much time and money on their hair, Rock says men are forced to adopt a hands-off policy. "You cannot touch a black woman's hair. You are conditioned not to even go there," he says. "When I was a dating guy, I dated women from different races. Anytime I was with an Asian or a Puerto Rican girl or a white girl, my hands would constantly be in their hair. <sep>What did Chris Rock's carpool ride help him discover?<sep>Hair

[Q]: You may be wondering, how can a glacier get so big? Why does it move? These are both good questions. In the winter months, precipitation falls as snow. This solid form of water builds up on the ground as long as the temperatures stay cold enough. As the temperature rises, the snow starts to melt. The frozen water changes state back into a liquid state. Nearer the poles, summer does not last very long. If the summer is long enough and warm enough, all the snow may melt. This is what typically happens now. The earth was a little cooler 12,000 years ago. As a result, during the summer months, that amount of snow did not melt. It may have only been an inch or so of snow that melted. The following winter, snow fell on top of this left-over snow. This next winters snowfall had a head start. Year after year, the snow that did not melt became thicker and thicker. Inch by inch the snow started to build up. Over many years, layer upon layer of snow compacted and turned to ice. <sep>What are two characteristics of glaciers?<sep>Not moving
[A]: No


[Q]: How would the universe look without gravity? It would have no planets and no stars. Thats how it looked when it was young. When the universe was young, there was only gas and dust. From this gas and dust, everything we now see was made. How were stars and planets created from just gas and dust? The answer is gravity. The same gravity that holds you down on Earth. The same force that causes your pencil to roll off your desk. The same force that causes it to fall to the floor. The invisible force of gravity caused dust and gas particles to be pulled together. This force is what formed all the objects in our solar system. This force formed the smallest moons. It also formed our Sun. This force caused more than just our solar system to form. It caused all the other solar systems to form. It caused the formation of all the galaxies of the universe. <sep>Did the universe always have a sun?<sep>Yes
[A]:
No
