(earth structure) Define Plate Tectonic Theory.

Geography
2 answers:
Svetlanka [38]3 years ago

Explanation:

Plate tectonics is the theory that Earth's outer shell is divided into several plates that glide over the mantle, the rocky inner layer above the core. The plates act like a hard and rigid shell compared to Earth's mantle. This strong outer layer is called the lithosphere, which is 100 km (60 miles) thick. The lithosphere includes the crust and outer part of the mantle. Below the lithosphere is the asthenosphere, which is malleable or partially malleable, allowing the lithosphere to move around. How it moves around is an evolving idea.

Answer:

okay

Explanation:

Play tectonics is a scientific theory describing the large scale motion of 7 large plates in the movements of a larger number of smaller plates of Earth's lithosphere since tectonic processes began on earth between 3.3 and 3.5 billion years ago

Which of these lists is arranged in order from smallest wavelength to longest wavelength?
guajiro [1.7K]

Answer:

b. wind waves, seiches, tsunami, tides.

Explanation:

The wavelength of water waves is calculated measuring the distances between the trough (low point) portion of a wave.  Usually, the bigger the wave, the greater the wavelength.

wind waves: small waves caused by the wind.  These waves tend to be small and with a short wavelength.

seiches: are usually waves on a lake or other closed water bassin.  They can be pretty high from a human perspective, so they are definitely bigger than wind waves.

tsunami: we all know how big the waves of a tsunami can be, totally wiping out coastal cities they encounter, so that's pretty big waves, and big waves tend to be larger apart (so with a bigger wavelength) than smaller ones.

tides: yes, a tide can be considered as a huge wave... that's running throughout the planet.  We barely see it as a wave because we can only see one wave at a time, the next wave being tens of thousands of mile away.
