A comprehensive overview of the concept of plate tectonics, a fundamental theory in the field of physical science. It delves into the idea of plate tectonics, the three main types of plate boundaries, and the formation of the supercontinent pangaea. The document also explores the concept of the ring of fire, tectonic plate boundaries, and the different types of plate interactions, including divergent, convergent, and transform fault boundaries. Additionally, it presents real-life examples of these plate boundaries, such as the mid-atlantic ridge, the himalayan mountains, and the san andreas fault. This document serves as a valuable resource for students and learners interested in understanding the dynamic processes that shape our planet.

OBJECTIVESOBJECTIVES Discuss the idea of plate tectonics. Identify the three types of plate boundaries.
What is Pangaea?
PRE-TEST PRE-TEST the name of a German scientist the name of the super-continent that existed millions of years ago I don't know the name of an ancient fossil
According to Wegener's
hypothesis of continental drift,
Earth's surface is made up of seven major landmasses the continents DO NOT move the continents were once joined together in a single landmass I don't know
WHAT IS PANGEA?WHAT IS PANGEA? Around 1915, a German scientist named Alfred Wegner proposed the Continental Drift Theory- which states that parts of the Earth's crust slowly drift atop a liquid core. The bases of this theory were map fit, fossil (Mesosaurus) evidence, mid oceanic ridges and continents structural similarities. He hypothesized that there was a gigantic supercontinent 200 million years ago, which he named PANGEA , meaning "All-earth". He also developed the Plate Tectonics theory. The theory stated that the earth's lithosphere is made up of individual plates that are broken down into over a dozen large and small pieces of solid rock called slab.
WHAT IS THE RING OF FIRE?WHAT IS THE RING OF FIRE?
The Ring of Fire is in the Pacific Ocean. It is made up of a string of
volcanoes, deep ocean trenches, and high mountain ranges. It is the
site of earthquakes around the edges of the Pacific Ocean.
The tectonic plates map of the Earth shows where mountain building,
volcanoes, and earthquakes have occurred.
WHAT IS A TECTONIC PLATE WHAT IS A TECTONIC PLATE BOUNDARY? BOUNDARY?
A tectonic plate boundary is the border between two plates. The
tectonic plates slowly and constantly move but in many different
directions. Some are moving toward each other, some are moving apart,
and some are grinding past each other. Tectonic plate boundaries are
grouped into three main types based on the different movements.

TECTONIC PLATES MAP SHOWING THE RING OF FIRE
The Earth is always on the move due to the motion of the tectonic plates.
Seven of the major plates make up most of the seven continents and the
Pacific Ocean. They are named after nearby landmasses, oceans, or
regions.
PLATEPLATE TECTONICS TECTONICS PARTS PARTS Plates are made of rigid LITHOSPHERE, the lithosphere is made up of the crust and the upper part of the mantle. Below the lithosphere (which makes up the tectonic plates) is the ASTHENOSPHERE.
1 2 TYPES OF TYPES OF PLATE PLATE BOUNDARIES BOUNDARIES DIVERGENT BOUNDARIES plates spread apart creating gap for the hot magma to rise and cool. The cooled magma then becomes new crust. Common along oceanic ridges. CONVERGENT BOUNDARIES plates collide (forming mountains) and destroyed as one crust dive beneath the other the process called SUBDUCTION. This process generates volcanoes. Ocean trenches are examples where Mariana trench in the Pacific Ocean is an example.

CONVERGENT BOUNDARIES the collision of the India Plate with the Eurasian Plate, creating the Himalaya Mountains , and the collision of the African Plate with the Eurasian Plate, creating the series of ranges extending from the Alps in Europe to the Zagros Mountains in Iran. HIMALAYA MOUNTAINS EXAMPLES EXAMPLES OF REAL OF REAL LIFE LIFE PLATE PLATE BOUNDARIES BOUNDARIES
THREE TYPES OF CONVERGENTTHREE TYPES OF CONVERGENT BOUNDARIES BOUNDARIES
CONTINENT-CONTINENT BOUNDARY
convergent boundary describes the collision of two tectonic plates
composed of continental lithosphere. Just like an oceanic-oceanic
convergent boundary, this type of boundary involves the compression of
the same type of lithosphere.
CONTINENT-OCEANIC BOUNDARY
When oceanic crust collides with a continent, an oceanic-continental
convergent boundary forms. The oceanic plate is denser, so it undergoes
subduction. This means that the oceanic plate sinks beneath the
continent, forming a deep ocean trench.
OCEANIC-OCEANIC BOUNDARY
describes a collision between two plates composed of oceanic lithosphere.
Even though this boundary involves the same type of lithosphere, one of
the plates will still subduct beneath the other.
