Mechanical weathering!!
Crag is 'Gaelic' meaning: Crack in the rock It's called a Tor
spheroidal weathering
Yes, there is a band called 420 who was influenced by several genres, including: oldies, 80s, and rock. Tim Brueggemann is the lead singer of the band.
ROCK
seismic waves actually the correct answer is S waves. trust me if you put seismic waves it will be wrong
p waves because they move rock back and forth which squeezes and strecthes the rock as they travel through the rock. s waves shear rock side to side as they travel through the rock
shear waves
Shear waves travel through solids, such as rock and metal. These waves propagate by moving particles perpendicular to the direction of wave travel, causing a side-to-side shaking motion.
Seismic waves, specifically shear waves or S-waves, cause particles in rock to move back and forth during an earthquake. These waves propagate by producing a side-to-side motion that leads to the shaking and fracturing of rocks.
P-waves are faster than s-waves. Both can pass through solid rock, but only p-waves can pass through gases and liquids === ===
P or Primary waves are longitudinal waves that move rock particles back and forth in the same direction that the wave travels.
shear stress
Seismic waves, such as compressional (P-waves) and shear (S-waves), can deform rocks by alternately compressing and stretching them as they pass through the Earth's crust during an earthquake. This can lead to the fracturing and displacement of rock layers.
A shear in a rock is a planar zone along which two bodies of rock have been displaced relative to each other.
S-waves cannot travel through liquids. When they reach the surface they cause horizontal shaking. Liquids don't have any shear strength and so a shear wave cannot propagate through a liquid. Think of a solid material, like a rock. ~Google
S waves cause rocks particles to move from side to side. The rock particles move at the right angles to the direction of the waves. However liquids can not support shear stresses and therefore S waves can not propagate through them.
