Erosion rates depend on the composition of the rocks and how they are attacked by the environment.
Different kinds of rocks have different composition and will erode at different rates.
Rocks in different places will be affected differently by wind, water, ice, rain, pollutants, etc. and so they will erode at different rates.

∙ 12y agono, rocks are made up of different minerals which make some rocks hard and some rocks soft (fissile). softer rocks like shale and sandstone will weather more quickly than harder rocks like granite.
There are lots of different types of weathering. some rocks such as limestone are susceptible to chemical weathering where rain water chemically alters the surface of the rock.

How can tree roots weather rocks?
Tree roots weather rocks because the roots go so deep under the ground that it can crack the rocks and then the rocks will eventually wear away when the water comes through from the ground.
How do physical weathering and chemical weathering affect rocks in the same way.?
Physical weathering and chemical weathering both break down rocks.
Why would boulder weather slowly while small rocks weather quickly?
1) The most obvious is that a boulder is significantly larger than a pebble or smaller boulder or rock. This would give the illusion of a smaller pebble weathering quiker than a boulder, when they are actually weathering at the same rate 2) The way they are being weather can be a factor. If you have a boulder being hit by only water or air while a pebble is all over the river bottom and sand than the pebble will weather quicker because there are more forces acting on it than the boulder.
How are rocks classified put in groups?
Rocks are classified by they way they are formed. There are three main classes of rocks: igneous, metamorphic and sedimentary rocks.
How are rocks and sand the same?
Rocks can differ in many ways -- too many to list. Two examples:Composition- The mineral composition is one way that rocks can differ. Some rocks, described as felsic, contain more silica and less iron and magnesium than mafic rocks. Rocks can further be divided by the proportions of these and other elements that they contain.Method of formation- Rocks can form in three main ways. Igneous rocks are solidified from melt. The speed of cooling and the composition of the magma from which they are formed determine the type of igneous rock. For example, basalt and gabbro have approximately the same composition, but different cooling speeds. Gabbro and granite have similar cooling speeds, but different compositions.Sedimentary rocks are formed by the lithification of sediments or precipitates. Again, they can be further divided by the composition of the rocks from which they are formed, as well as by grain size. Additionally, the method of sedimentary formation (biochemical, chemical, or clastic) determines the type of sedimentary rock. For example, limestone can be formed as a biochemical sedimentary rock (fossiliferous limestone), a chemical sedimentary rock (travertine), or a clastic sedimetary rock (clastic limestone).Metamorphic rock is formed when a rock undergoes pressure and/or heat without melting. The amount of heat or pressure as well as the direction of any applied pressure influences the type of metamorphic rock produced. The amount of time over which the rock is exposed to pressure or heat also affects the rock produced. For example, rocks such as gneiss experience differential pressure, which causes foliation to occur. In contrast, quartzite does not experience such differential pressure, and is not foliated.
Why are there different kinds of moons?
Moons are big rocks in space so they are not created all the same way.
How are some kinds of rocks the same?
By the way they look
Is sedimentary rocks formed the same way normal rocks are?
No, because a sedimentary rock is formed from pieces of other rocks.
How does climate affect weather?
Weather happens from day to day, often quite different. Climate is weather, but averaged out over years. If the weather changes, and keeps changing in the same way, getting drier, for example, then eventually it changes the way we regard the climate for that region.
When you look at a metamorphic rock how can you tell it is one?
Understand that metamorphic rocks are those that have changed in some way by heat or pressure or both. Sedimentary rocks are formed from sediments and igneous rocks are formed by fire. When these rocks change again, they become metamorphic. Marble is one type of metamorphic rock.Look at the way the grain are formed. In schist rocks, you can see that the layers and the grains all go the same way. Warning Metamorphic rocks are difficult to classify because different amounts of heat or pressure to the same rock can look different.
How are moon rocks dated?
The same way as terrestrial rock--radiometrically.
How are moons and planets alike?
Most but not all larger MOONS (bodies that orbit planets, moons, or asteroids) accreted in the same way that PLANETS did, assuming a variable density and a nearly spherical shape. Very large moons such as Titan have many of the characteristics of planets: vulcanism, atmospheres, and weather. Generally speaking, moons orbit planets in the same way that planets orbit stars.
How did Magellan survive the weather?
The same way all sailors do with a lot of luck and a prayer.
How can tree roots weather rocks?
Tree roots weather rocks because the roots go so deep under the ground that it can crack the rocks and then the rocks will eventually wear away when the water comes through from the ground.
How do physical weathering and chemical weathering affect rocks in the same way.?
Physical weathering and chemical weathering both break down rocks.
Why do moon rocks reflect light?
The rocks on the moon reflect light the same way that rocks on Earth do. The moon only looks bright because it is set against the darkness of space.
How do Sedimentary rocks change to Metamorphic?
Sedimentary rocks change to metamorphic the same way any other rock would: through heat and pressure.
