Activity 1: Tell me more! Directions: Underline the appropriate word in the statement. 1. The crust and a part of the upper mantle make up the (continent, lithosphere). 2. It is subdivided into portions called plates. (Continents, Plates) are large pieces of the upper few hundred kilometers of Earth that move as a single unit as it (floats, moves) above the mantle. 3. There are two kinds of crust: (Continental, Crustal) plates which are thicker but less dense, and Oceanic plates which are thinner but (compact, denser). Plate Tectonics is a (law, theory) which suggests that Earth's crust is made up of plates that constantly (move, rotate) and interact in various ways, thus, producing earthquakes, mountains, volcanoes, and other (geologic, land) features. 4. 5. The plate that pushes the Philippine Plate towards the (Eurasian, Indo- Australian) plate is the Pacific Plate. 6. The world's earthquakes, (eruptions, volcanoes), and mountain ranges are not randomly distributed over the Earth's surface. They are both situated at the same (location, place) near the (center, edges) of the continents. 7. Geologic activities such as (ethnicity, seismicity) or the occurrence of earthquake, (extravasation, volcanism), and mountain formations are the (basis, reasons) of scientists in dividing Earth's lithosphere.

Plate tectonics from the Late Latin: tectonicus, from the Ancient Greek: τεκτονικός, lit. 'pertaining to building')[1] is the generally accepted scientific theory that considers the Earth's lithosphere to comprise a number of large tectonic plates which have been slowly moving since about 3.4 billion years ago.[2] The model builds on the concept of continental drift, an idea developed during the first decades of the 20th century. Plate tectonics came to be generally accepted by geoscientists after seafloor spreading was validated in the mid to late 1960s.
