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?

Project information: the pythagorean theorem can be used in many real-world scenarios. the following is an example of real-word scenario where you will use the pythagorean theorem to find the missing piece. real-word scenario: a handyman needs to create triangular trusses to frame out the roof of a small shed. he knows the roof itself will be 9 feet tall and the length of each truss will be 14 feet. how long will the roof be from its highest to lowest point? part 1: the handyman created a drawing to provide a visual to solve this problem. below is his drawing. 1. part 2: solve the real-life scenario. show all your steps in answering the question and make sure you label your final answer correctly.
