Question

slide 7
what type of weathering does each example describe.
water dissolves the materials in rock select
materials break down the rock select
tumbled rocks that are round select
acidic water reacts with rock select
ice that pushes and shapes rock formations select

Explanation:

Weathering is the breakdown of rocks. Chemical weathering involves chemical reactions changing the rock's composition. Physical weathering breaks rock physically without changing its chemical makeup. Water dissolving rock materials is chemical weathering as it involves a chemical - like dissolution process. Materials breaking down rock can be either chemical or physical depending on the materials and process. Tumbled rocks becoming round is physical weathering due to abrasion. Acidic water reacting with rock is chemical weathering as it is a chemical reaction. Ice pushing and shaping rock formations is physical weathering as it is a physical force - based process.
