Shared Flashcard Set Occurs when saltwater enters a crack in a rock and then evaporates. It leaves behind salt crystals which can exert force and enlarge the cracks. common near coastlines as salty spray constantly hits the rocks.

Types of erosion Scalding. Scalding can occur when wind and water erosion removes the top soil and exposes saline or sodic soils. Raindrop impact alone can result in large amounts of soil being moved. However water or wind moving over the surface will remove more soil, and contribute to sheet, rill and gully erosion. Erosion also tends to remove the lighter, smaller soil particles first (such as clay and silt), leaving fine and coarse sand behind. A combination of large amounts of fine sand and small amounts of clay at the surface means the soil tends to seal and set hard, which limits infiltration (water entering the soil).

Introduction to rocks Porous rocks. Rocks with rounded grains are more likely to absorb water than rocks with interlocking grains. This is because the water can get into the gaps between the grains. Rocks that absorb water are called porous.Rocks with rounded grains are usually softer and more crumbly than rocks with interlocking grains.ocks with rounded grains are more likely to absorb water than rocks with interlocking grains.

Weathering Weathering is the breaking down of rocks, soil and their minerals through direct contact with the Earth's atmosphere, waters, or living things. Weathering occurs in situ. It is a type of erosion. Erosion is where rocks and minerals are moved downhill by water, ice and wind.

- Silt is often found in river estauries, because the fine particles are washed downstream and deposited when the water flows more slowly. SAND is small pieces of rock (2mm to .05mm diameter) such as quartz or sandstone. Sand particles are large enough to allow water to drain easily, but they do not hold water and are easily blown around when dry. STONES, ROCKS AND BOULDERS are larger pieces of rock which are too big to form part of the soil but are found in many gardens. Under the surface layer of soil, they can help drainage. As well as rock, soil contains organic material, formed from decayed plants or animals.

Karst Topography - Teacher's Guide and Paper Model The development of all karst landforms requires the presence of rock which is capable of being dissolved by surface water or ground water. The term karst describes a distinctive topography that indicates dissolution (also called chemical solution) of underlying soluble rocks by surface water or ground water.inkholes (also known as dolines) are surface depressions formed by either: 1) the dissolution of bedrock forming a bowl-shaped depression, or 2) the collapse of shallow caves that were formed by dissolution of the bedrock. These sinkholes or shallow basins may fill with water forming lakes or ponds.

Weathering and erosion Water gets into cracks and joints in bedrock. When the water freezes it expands and the cracks are opened a little wider. Over time pieces of rock can split off a rock face and big boulders are broken into smaller rocks and gravel. This process can also break up bricks on buildings.

- CHAPTER 6 (Weathering and Soil). 1. Weathering is a term which describes the general process by which rocks are broken down at the Earths surface into such things as sediments, clays, soils and substances that are dissolved in water. 2. The process of weathering typically begins when the earths crust is uplifted by tectonic forces.

- Soils retain rainwater so that rocks covered by soil are subjected to chemical reactions with water much longer than rocks not covered by soil. Soils are also host to a variety of vegetation, bacteria and organisms that produce an acidic environment which also promotes chemical weathering. 2. Minerals in a rock buried in soil will therefore break down more rapidly than minerals in a rock that is exposed to air.

- Weathering is the breakdown of rock by physical, chemical or biological processes. Limestone areas are predominently affected by chemical weathering when rainwater, which contains a weak carbonic acid, reacts with limestone. When it rains limestone is dissolved.ver the years this sediment was compressed to form solid rock. Limestone is formed in layers-called bedding planes. These bedding planes contain vertical cracks called joints. Joints and bedding planes make the rock permeable.

Soils - Part 2: Physical Properties of Soil and Soil Water Soil acts as a sponge to take up and retain water. Movement of water into soil is called infiltration, and the downward movement of water within the soil is called percolation, permeability or hydraulic conductivity. Pore space in soil is the conduit that allows water to infiltrate and percolate.

Groundwater Groundwater (or ground water) is the water present beneath Earth 's surface in soil pore spaces and in the fractures of rock formations. A unit of rock or an unconsolidated deposit is called an aquifer when it can yield a usable quantity of water.The depth at which soil pore spaces or fractures and voids in rock become completely saturated with water is called the water table.Groundwater is recharged from, and eventually flows to, the surface naturally; natural discharge often occurs at springs and seeps, and can form oases or wetlands.he depth at which soil pore spaces or fractures and voids in rock become completely saturated with water is called the water table.

- through soil. Infiltration is defined as the downward entry of water into the soil or rock surface (SSSA, 1975) and percolation is the flow of water through soil and porous or fractured rock. In hydrologic. modeling, these two processes are usually modeled separately. Infiltration rate is the rate at which a soil.
