what should you do when you jump into deep water when wearing a lifejacket
how deep should water line be from meter to house in Versailles Kentucky
I think this question needs to be expanded to get an answer. I think the question is on the question of slides in pools. a pool should be 5 feet deep for a slide and it is not recommended to install a slide on an above ground pool. the waves from landing in the water push very hard on the oposite side of the pool and in time will weaken the walls. Answer:: Slides like diving boards are a liability.
Crocodiles don't generally dive, the slide into the water from a bank and swim close to the surface to break for air.
0, 21ftx4ft is a flat surface, water will just slide off
Dry them.
steer into the slide.
Rock samples of the ocean floor can be acquired through various methods such as deep-sea drilling or collecting samples using submersibles or remotely operated vehicles. Scientists also study samples brought up during underwater volcanic eruptions or through natural processes like landslides and fault movements. These samples provide valuable insights into the composition and history of the oceanic crust.
Drip irrigation lines should be buried about 6-12 inches deep to ensure optimal water distribution and efficiency.
Physical samples of rock extracted (taken) from deep within Earths crust.
Deep sea floor samples can be taken using a variety of methods. The use of sonar machines and robotic mechanisms are what is typically used these days. These machines are used to extract various materials from the sea to be examined and studied.
