Science Unit 1, lesson 1

The main topic is the Plate tectonic theory and how it formulates geological features and activities.

Explain the formation of diff geological features and phenomena; states that the Earth’s lithosphere is composed of plates that move and interact.

Plate tectonics theory

Means to build

tectonic/ tectonicus/ tektonikos.

outermost layer of earth; composed of the upper mantle and the crust.

lithosphere

various types of rocks and sediments floating above the upper mantle

crust

2 types of crust:

oceanic and continental

the 7 major plates

North American, South American, Eurasian, Pacific, Indo-Australia, African, and Antartic plates.

The intermediate plates are

Philippines, Carribean, Nazea, Scotia, Juan de Fuca, and Arabian plates

why does the Philippines have so many volcanoes and always experience earthquakes?

Earthquake distribution

They are called surface waves

Long surface and Rayleigh waves.

Most earthquakes and volcanoes lie along what?

boundaries of plates.

Charles Wyville Thomson

A German meteorologist who hypothesized “Pangaea”?

Alfred Wegener

Chains of mountains

Mountain ranges

discovered that the ocean floor is not smooth, but rough.
