What causes a rock to break?
Rocks break due to various factors such as stress from external forces like temperature changes, pressure, or impacts. Additionally, rocks can break due to chemical weathering processes that weaken the mineral structure of the rock over time, eventually leading to fractures and breakage.
How is smashing a rock physical change?
Smashing a rock is a physical change because it alters the rock's appearance and size, but not its chemical composition. The pieces of the rock remain the same material and can potentially be put back together.
What could be an obstruction to waves?
An obstacle in the water, such as a rock or a pier, can obstruct waves and cause them to break or change direction. Additionally, underwater structures like reefs or sandbars can also disrupt wave patterns. Wind direction and strength can also impact the formation and direction of waves.
How was the water level by the rock affected by the waves?
The water level by the rock was rising and falling due to the incoming waves. The waves would cause the water level to increase as they approached the rock and then recede as they moved away from it.
What Squeezes and pulls rock in the same direction that the wave travels?
Seismic waves, specifically compressional (P-waves), squeeze and pull rock in the same direction that they travel. These waves cause particles in the rock to oscillate back and forth along the direction of propagation.
What do waves make when they break rock into small pieces?
Waves breaking against rocks can cause hydraulic action, where the force of the water compresses and weakens the rock, leading to its eventual breakdown into smaller pieces through erosion and abrasion.
How do rocks break into smaller pieces?
You smash a rock with a bigger rock
Explain the difference between cleavage and fracture.?
Cleavage is when you can break the rock into square like pieces and Fracture is when you break a rock into uneven different shaped pieces.
What are 2 ways that rocks break in tiny pieces?
Rocks can break into tiny pieces through weathering processes such as frost wedging, where water gets into cracks in rocks and expands when it freezes, causing the rock to break apart. Another way is through chemical weathering, where minerals in the rock react with water and air, causing the rock to crumble into smaller pieces.
Weathering and erosion break igneous and other types of rock into smaller pieces called what?
Weathering and erosion break igneous and other types of rock into smaller pieces called sediments.
Waves pounding aganst rock is an example of which process?
The waves pounding against the rock is an example of the process of erosion. Over time, the force of the waves can break down and wear away the rock surface.
Why can't a delta form at a river mouth where the waves are strong?
the waves carry the sand and pieces of rock that form the delta away.
What does rock particles mean?
All of these changes break rocks into smaller pieces called rock particles
How does solid rock break into smaller pieces?
Solid rocks break into smaller pieces because weathering could take bits and pieces of the rock. Then erosion carries the rock to some were else. Finally deposition will drop the rock in that place were the erosion brought it.
What process breaks off pieces of a cliff?
The process that breaks off pieces of a cliff is called erosion. Erosion can be caused by factors such as water, wind, ice, or waves. Over time, these forces wear down the rock and soil, causing pieces to break off and fall from the cliff face.
What natural activies work to break down rock?
water, wind, waves, and gravity
What is the point where rock break and release energy in the form of seismic waves?
The focus, or hypocenter.
