How deep can we go?

Quick question for extra cred: Are deep ocean trenches from converging or diverging plates?

Quick question for extra cred: Are deep ocean trenches from converging or diverging plates?

Quick question for extra cred: Deep ocean trenches are from converging plates? explain!

Surprisingly, the deepest ocean trenches occur (happen) when one plate is getting pushed below another… _ _ _ _ _ _ _ _ _ _ _

Surprisingly, the deepest ocean trenches occur (happen) when one plate is getting pushed below another… S _ _ _ _ _ _ _ _ _ _

Surprisingly, the deepest ocean trenches occur (happen) when one plate is getting pushed below another… S _ B _ U C _ _ I O N

Surprisingly, the deepest ocean trenches occur (happen) when one plate is getting pushed below another… SUBDUCTION.

Surprisingly, the deepest ocean trenches occur (happen) when one plate is getting pushed below another… SUBDUCTION (creating volcanoes).

Deep ocean trenches happen when one plate gets pushed below another (SUBDUCTION--creating volcanoes) at the edge of oceanic plates.

Deep ocean trenches happen when one plate gets pushed below another (SUBDUCTION--creating volcanoes) at the edge of oceanic plates.

How do we know this?

SCUBA diving is great for the NERITIC zone…but NOT for the BENTHIC zone.

Why can’t we go deeper?

Why can’t we go deeper? PRESSURE!!!!

So, how do we get to the bottom of all this?

DEEP OCEAN EXPLORATION 1. SUBMERSIBLES! HUMAN DRIVEN

DEEP OCEAN EXPLORATION 1. SUBMERSIBLES! HUMAN DRIVEN

DEEP OCEAN EXPLORATION (3 ways) 1. SUBMERSIBLES! HUMAN DRIVEN

How deep can man in submersibles travel?

Deep ocean exploration SUBMERSIBLES…human driven (1/2 way down)

submersibles can only go HALF WAY DOWN to the deepest abyss HOW DEEP IS 4,000 METERS?

6,000 meters is as tall as DENALI the tallest mountain in the USA

Deep ocean exploration (3 ways) SUBMERSIBLES…human driven (1/2 way down)

So how do Marine biologists get this deep? HOW DEEP IS 11,000 METERS?

Here we are at 11,000 meters ABOVE sea level… https://www.youtube.com/watch?v=qjPcNujFzI 0

it’s really far down! Verry difficult!

we can measure it without going down so far?

Noooo, not this way, dufus.

SONAR

Deep ocean exploration (3 ways) SUBMERSIBLES… HUMAN DRIVEN (1/2 way down) SONAR (SOUND WAVES) MAP OCEAN FLOORS!

But, how do get pics of this quirky thing?

…or this weird guy with the see-thru head?

Life exists even in the ABYSS! HOW DO WE GET DOWN THERE ? http://news.discovery.com/animals/deep-sea- amoeba-life-111023.html

So how do scientists get this deep?

How can we investigate the deepest ocean? ROV’s!!!! …what does this stand for????

How can we get investigate the deepest ocean? ROV’s (REMOTELY OPERATED VEHICLES!)

How can we get to videos and photos from the deepest ocean? ROV’s (REMOTELY OPERATED VEHICLES!)

Deep ocean exploration (3 ways) SUBMERSIBLES…human driven (1/2 way down) SONAR (sound waves) MAP OCEAN FLOORS! ROV’s (REMOTELY OPERATED VEHICLES!) DEEPEST, SAFEST, no risk to humans!
