Jake Bryant played hockey for seven years. He was the goalie in an advanced youth hockey league in Colorado. During the last two years that Bryant played, he suffered five concussions. This forced him to retire from the sport at age 16. Hockey player Alexandra "Z" Karlis, age 17, was also sidelined by a concussion. She sustained a brain injury when a player on the opposing team blindsided her with an elbow to the head. Protecting kids from the long-term effects of concussions is the motivation behind Senate Bill 40, which Colorado recently signed into law.

1) earth's crust is made up of relatively rigid plates that ride atop earth's hot, semiliquid mantle. (2) the plates are called tectonic because they're in constant motion. (3) they can move because earth's mantle is a very hot and semiliquid fluid called magma. (4) volcanoes are a result of magma rising up or erupting through a plate, particularly where plate boundaries are moving against each other. (5) also, when plates slide against each other, causing friction along adjacent plate boundaries, earthquakes frequently occur. (6) therefore, we often find volcanoes and earthquakes along plate boundaries. (7) plates may also collide. (8) when that happens, mountain ranges are formed. (9) for example, the collision of the plate carrying the indian subcontinent created the himalayan mountains when it collided with the asian plate. which statement about this paragraph is accurate?
