El tango no es uno de los símbolos culturales más importantes de Argentina.

Los turistas pueden ver cataratas, montañas, y muchas plantas exóticas en los parques nacionales de Costa Rica. 

The illustration below shows some of Earth’s tectonic plates. The arrows indicate the direction in which some of these plates are moving.Based on the direction of the Cocos Plate, what type of plate boundary likely exists between the Cocos Plate and the Caribbean Plate? (Hint: Step 1. Analyze the likely relative motions of the Caribbean Plate and the Cocos Plate. Step 2. Relate the relative motions of plates to the type of plate boundary.)

Imagine you could travel in a straight line through Earth from a point on one side and come out on the other side. What compositional layer would you travel through in the exact center of Earth?

How is the outer core of Earth different from the inner core?

In 1912, Alfred Wegener suggested the hypothesis of

Mantle convection causes tectonic plate motion and is responsible for the slow movement of continents. Which of the following processes causes one tectonic plate to sink beneath another at a subduction zone?

Huge, underwater mountain ranges are called:

Most tectonic plates have both oceanic and continental crust. How are oceanic and continental crust different?

Scientists divide Earth into three main layers: the core, the mantle, and the crust. How are these three layers identified?
