/04 Weathering (Pg. 295-297, 299) Weathering Sediment comes from rocks that have down or worn away by a natural process called Rocks can be mechanically, or. Mechanical Weathering weathering is the physical or disintegration of rocks. change can also cause weathering. When days are warm and nights are cold we call this the freeze- thaw period. At night when the temperature falls below the water freezes and, pushing the cracks apart. Each day more water can fill these cracks. The water continues to freeze and eventually the rock breaks. This process is called Another type of weathering occurs when wind and wear away the of rocks and carry the pieces to place, where the pieces build up. is the part of the process responsible for " " and is the part responsible for" Chemical Weathering weathering involves the or decomposition of minerals as a result of reaction with, with other dissolved in, or with in the air. Biological Weathering weathering is the breakdown of rock caused by organisms such as,, or

Grade 7 Science Student: (lass: 10 J Sedimentary Rock (page 292) Sedimentary Rock is made from -- loose material, such as hits of,, and and the rock we see on Earth's surface. remains. These sediments become eioseh packed and together. Sedimentary rock makes up about Formation of Sedimentary Rock (page 293) % of Sediment slowly settles on top of other sediment layers called. The weight of the other sediment and water on top of it causes a squeezing together called. is one of the most common and useful sedimentary rocks. Acadia School's outer walls are made of limestone. It often contains the remains of once-living things called. Three other examples of sedimentary rocks are» and Metamorphic Rock (page 294) and _ are just two examples of the third family of rock. Metamorphic means " This type of rock may be formed below Earth's when extremely high and cause the original rock, or rock, to change form. Granite will change into if it is squeezed together by enough pressure. i
mmm M ant Types of Rock Igneous rode When magma - either above or below ground level - cools and hardens, it Is called Igneous rock. Igneous rock Is made up entirely of mineral crystals. Extrusive igneous rock- formed above Earth's surface - cools quickly. The crystals are small and packed closely together. The rock is usually smooth and evenly coloured. Intrusive Igneous rock - formed below the Earth's surface - cools very slowly, which allows the crystals to grow large. Granite is the most common example of intrusive rock. Obsidian, felsite, and pumice are other examples. Metamorphic rock: Rock that has changed due to massive pressure and extremely high temperatures Is called metamorphic rock. Most metamorphic rock is created deep in Earth's crust, as rocks are folded and compressed beneath other rocks. The pressure and heat cause the crystals to realign or recrystallize. Examples are marble (from limestone), slate (from shale), and gneiss (from granite). Metamorphism is a very slow process that takes millions of years. Sedimentary rock: Over time, exposed igneous or metamorphic rocks undergo weathering. The sediment created eventually settles In lakes or oceans. As more sediment is deposited, the layers become compacted, forming sedimentary rock. This process Is called llthlfkxitlon. Some examples of sedimentary rock are sandstone, limestone, and shale. Fossils are found in sedimentary rock. Sedimentary rock is usually soft and easily erected in comparison to igneous and metamorphic rocks.
