Oceanography
Who discovered oceanography
Matthew Fontaine Maury
What is SCUBA
a type of underwater diving whereby divers use breathing equipment that is completely independent of a surface air supply. The name "scuba", an acronym for "Self-Contained Underwater Breathing Apparatus"
What are the earths layers
When was volcanoes first discovered
1,500 BC
who discovered tectonic plates
The "Father of Plate Tectonics", Alfred Wegener
When was it discovered
130 years in the late 19th century
Who invented SCUBA
Jacques Cousteau
who discovered the earths layer
Layers were deduced by Sir Isaac Newton
Who discovered the first volcano
Voyager 1 imaging scientist Linda Morabito.
When was tectonic plates first found
Plate tectonic theory had its beginnings in 1915
What does it study?
Wide range ecosystem, ocean circulations and tectonic plates.
When was SCUBA diving equipment inverted
1943
Which earth layer has liquid
The outer core is the liquid largely iron layer of the earth that lies below the mantle
What was the worlds biggest volano
Ojos del Salado
How do tectonic plates work
the lithosphere, is separated into plates that move over the asthenosphere, the molten upper portion of the mantle. Oceanic and continental plates come together, spread apart, and interact at boundaries all over the planet.
What does physical oceanography study?
conditions and physical processes within the ocean
What does it stand for?
Self- contained Underwater Breathing Apparatus
Which earth layer is the driest?
inner core
Where are they located
the boundaries between tectonic plates. Most volcanoes are found along a belt, called the “Ring of Fire” that encircles the Pacific Ocean. Some volcanoes, like those that form the Hawaiian Islands, occur in the interior of plates at areas called “hot spots.”
How do tectonic plates move
Plate tectonics move because they are carried along by convection currents in the upper mantle of the planet
What is chemical oceanography
The study of chemical components of the ocean
What does it take to scuba dive
you need to have basic swim skills and be able to comfortably maintain yourself in the water. Your PADI Instructor will assess this by having you: Swim 200 metres/yards (or 300 metres/yards in mask, fins and snorkel).
How many earth layers are there
four
How do they work
On land, volcanoes form when one tectonic plate moves under another.
Are tectonic plates dangerous
ome of the most destructive natural hazards that occur on Earth earthquakes, tsunamis and volcanic eruption are associated with tectonic plate boundaries.
