Why aren't all rocks the same?
Rocks are not the same because, they come from either a Volcano, or they are broken from the Earth's ground. So this causes it to be different shapes and sizes.
Whats wrong with quarrying?
Quarrying is a place that has rocks that has been excavated from the ground. This is also known as an open-pit mine.
Suppose a rock is dropped off a cliff with an initial speed of 0 m per sec What is the rocks speed after 5 seconds in m per sec if it encounters no air resistance?
9.8m/s(5)= 49
Suppose a rock is dropped off a cliff with an initial speed of 0 ms What is the rocks speed after 3 seconds in ms if it encounters no air resistance?
The acceleration of gravity is 9.8 m/s2Speed after 3 sec = (9.8 x 3) = 29.4 m/s
What are real life examples of inclined planes?
Civil engineers need to know how much they have to slope the ground around roadways. If the slope isn't right we end up with debris sliding down embankments into roadways. Falling rocks, anyone?
A 12 kg rocks falls from rest off a cliff and hits the ground in 1.5 s.without considering air resistance what is the rock s velocity just before it hits the ground?
The velocity is gravity acceleration x time or (9.8)(1.5) = 14.7 m/s. The velocity is not dependent on the mass.
What happens when rocks fall down a cliff?
It falls and break
If you rolled two rocks of a cliff which one would hit the ground first?
it depends wich two kind of rocks are u rolling???
What is a rock at the top of a cliff that suddenly falls?
A rock that falls suddenly from the top of a cliff is usually referred to as a rockfall or rockslide. This can happen due to factors like erosion, weathering, seismic activity, or human interference, and can pose a danger to anyone below the cliff.
What is it called when a large rock falls from a cliff?
It is called a rockfall. Rockfalls can occur due to weathering, erosion, or seismic activity, leading to rocks breaking loose and falling down a slope or cliff.
If rock at rest falls off a cliff and hits the valley below after 3.5 seconds what is the rocks velocity as it hits the ground?
The final velocity of a falling object can be worked out by the use of the formula a = (v - u)/t a = acceleration due to gravity = 9.8 m.s-2 v = final velocity = unknown u = initial velocity = 0 t = time taken = 3.5s Factor these known values into our equation 9.8 = (v - 0)/3.5 rearrange the formula to workout the unknown value v = 9.8 x 3.5 Final velocity on impact with valley floor = 34.3 m.s-1 with a downwards direction
What is a cliff-base heap of rocks?
scree
A large rock falls from a cliff and break mechanical or chemical weathering?
When a large rock falls from a cliff, it primarily demonstrates mechanical weathering. This process occurs as the rock breaks apart due to physical forces, such as impact with the ground or other rocks, without altering its chemical composition. Over time, further exposure to elements like wind, water, and temperature changes may lead to additional mechanical weathering, while chemical weathering would involve changes in the rock's minerals due to chemical reactions.
What type of rock is a cliff made of?
A cliff can be made of various types of rocks, depending on the location and geological history of the area. Common types of rocks found in cliffs include sedimentary rocks like sandstone, limestone, and shale, as well as metamorphic rocks like schist and gneiss, and igneous rocks like granite and basalt.
How is a cliff created?

A block of rocks soil and vegetation slowly collapses down a curved surface leaving a crescent-shaped cliff behind it. What type of mass movement is this?
This is likely a rockfall, which occurs when a block of rocks, soil, and vegetation detaches and falls down a steep slope. The curved surface and crescent-shaped cliff are common features of rockfalls due to the trajectory of the falling material.
What is cliff retreat?
A cliff retreat is a form of natural erosion. Rocks in the face of the cliff are broken down by wind and water (rain, waves, etc). The material in the cliff is loosened, and parts of the cliff face collapse. Eventually, an entire section of the cliff will fall into the sea, meaning that the cliff edge has retreated. The pace of cliff retreat is determined by the strength of the rocks in the cliff face, more than the cliff's height. It also most often occurs where the base of the cliff is continually being saturated by water, weakening the rock further.
