The Plate Tectonic Tour

A transform boundary is when two tectonic plates slide past each other, going in opposite directions. A transform boundary causes earthquakes and faults. You can see a very well known transform plate boundary in California, it's called the San Andreas fault. Earthquakes are extremely common there, because of the fault. It isn't too hard to get there either. For example, if you live in the Dallas-Fort Worth area it won't take you too long to get to the San Andreas fault. It is 1,486.9 miles away from the DFW airport.
A convergent plate boundary is when two tectonic plates move toward each other and collide. Convergent plate boundaries cause volcanoes and mountains. The Himalayas were formed as a result of the Eurasian plate and the Indo-Australian plate colliding. Earthquakes can occur in the area, and one of the more recent ones is the Nepal earthquake. The Nepal earthquake was caused by a thrust fault. However, if you live in the United States, it is farther away. For example, the Himalayas are 8,182 miles away from the DFW airport.

A divergent plate boundary is when two tectonic plates move away from each other. Divergent plate boundaries cause rifts and mid-ocean ridges. The Rio Grande rift in Mexico was caused by a divergent plate boundary. Earthquakes have occurred in the area. In fact, some think that historical earthquakes in the area hint at the potential for larger earthquakes in the future. It can be kind of far away depending on where you live. For example, if you live in Texas it will be closer than if you live in New York. In fact, the Rio Grande rift is only 511 miles from the DFW airport.

Topographic map of the Himalayas
A topographic map measures elevation. Each contour line measures the same amount of elevation. There is usually a key that shows how much in elevation each contour line is.
