Drag each label to the correct location on the chart. classify each process as weathering or erosion.

weathering - colorado river carves land in arizona to form the grand canyon. cracks form in a sandstone wall surrounding a house. a marble statue near the science museum is changing color due to rainfall

erosion - after a rainstorm, soil and rock piees litter the roadways. the sand dunes in the sahara desert are changing shape.

here's your answer.

1. The Colorado River carves land in Arizona to form the Grand Canyon- Erosion

2. Cracks form in a sandstone wall surrounding a house- Weathering

3. A marble statue near the science museum is changing color due to rainfall- Weathering

4. After a rainstorm, soil and rock pieces litter the roadways- Weathering

5. The sand dunes in the Sahara Desert are changing shape- Weathering

Explanation:

Weathering is the process where rock is dissolved, worn away or broken down into very small pieces.

Erosion happens when rocks and sediments are picked up and moved to another place by ice, water, wind or gravity

A reaction is exothermic if ΔH (or in some textbooks) is negative:

H₂ + Br → 2 HBr, ΔH A reaction is endothermic if ΔH is positive:2 NH₃ → N₂ + 3 H₂, ΔH > 0.2 HCl → H₂ + Cl₂ ΔH > 0.Explanation

The enthalpy of a system is the sum of its internal energy. ΔH

Similarly, ΔH > 0 indicates that the reactants gains internal energy in the reaction. Energy conserves. As a result, the reaction must have gained energy from its surroundings. The reaction will be endothermic since it absorbs heat.

Lets do numbering of the labels to make labelling clear.

1. The Colorado River carves land in Arizona to form the Grand Canyon.

2. Cracks form in a sandstone wall surrounding a house.

3. A marble statue near the science museum is changing color due to rainfall.

4. After a rainstorm, soil and rock pieces litter the roadways.

5. The sand dunes in the Sahara Desert are changing shape.

Weathering:

2. Cracks form in a sandstone wall surrounding a house.

3.A marble statue near the science museum is changing color due to rainfall.

Erosion:

1. The Colorado River carves land in Arizona to form the Grand Canyon.

4. After a rainstorm, soil and rock pieces litter the roadways.

5. The sand dunes in the Sahara Desert are changing shape.

Explanation:

Weathering and erosion, in both the processes rocks are broken down into particles but both the processes are different from each other. Weathering can be physical, chemical or biological process in which rock particles degrade without any movement while erosion is purely a movement of sediments in which particles move from one place to another under the influence of water and wind.

So, on the basis of this difference we can classify each label to the correct location:

Weathering (no movement of particles after degradation):

2. Cracks in a sandstone wall of a house.

3. Changing color of marble statue due to rainfall.

Erosion (Movement of particles from one place to another):

1. Formation of Grand Canyon, when the Colorado River carves land in Arizona.

4. Soil and rock pieces litter on roadways after rainstorms.

5. Changing shape of dunes in sahara desert.
