Netflix – episode one start at 27:13 11 billion years ago the milky way galaxy was formed. 4.5 billion years ago, our sun and solar system was born. Life on earth (not human life!) began 3.5 billion years ago. Humans evolved on the last day human history has only taken place during the last 14 seconds on the cosmic calendar.

Pangaea what was it? 1) was a supercontinent that formed approximately 300 million years ago. 2) It began to break apart around 100 million years after it formed. 3) The single global ocean which surrounded Pangaea is named Panthalassa.

What evidence is there that points to the existence of Pangea? The distribution of fossils across the continents

Continental Drift Movement of the earth’s crust The plates slowly moved to where they are today. Moves about 0.8- 2 inches a year

Types of Earth Movements 1). Convergent: when 2 plates collide into each other Result s mountains formed *highest base below water – Mauna Kea (13, 802) * Largest volume of a mountain – Mauna Loa (33,474 ft.) *The highest mountains above sea level are generally not the highest above the surrounding terrain. There is no precise definition of surrounding base, but Mount McKinley, Mount Kilimanjaro and Nanga Parbat are possible candidates for the tallest mountain on land by this measure. The bases of mountain islands are below sea level, and given this consideration Mauna Kea (4,207 m (13,802 ft) above sea level) is the world's tallest mountain and volcano, rising about 10,203 m (33,474 ft) from the Pacific Oceanfloor. The highest mountains are also not generally the most voluminous. Mauna Loa (4,169 m or 13,678 ft) is the largest mountain on Earth in terms of base area (about 2,000 sq mi or 5,200 km2) and volume (about 10,000 cu mi or 42,000 km3), although, due to the intergrade of lava from Kilauea, Hualalai and Mauna Kea, the volume can only be estimated based on surface area and height of the edifice). Mt. Everest- elevation 29,029 ft. (5.5 mi) 13,

Types of Movements 2). Divergent: when 2 plates separate from each other Result s valleys formed

Types of Movements 3). Transverse: when 2 plates rub against each other Result s earthquakes

Pacific Ring of Fire A majority of the world’s fault activity falls along the edge of the Pacific Ocean
