Aim: To investigate the weathering of marble due to acid rain. Hypothesis: The larger the surface area the quicker the reaction. Because there will be more surface area or room to collide with the marble chip particles therefore resulting in a quicker reaction. The smaller the surface area‚ the slower the reaction will be as there will be fewer particles so less chance of a collision and a lower rate of reaction. Equipment: • 1x Test Tube Rack • 2x Test tubes • 1x Delivery

Natural Bridge Cavern Tour This was my third trip to the Cavern in the last five years‚ but I believe this is the first time that I have taken the time to appreciate the time line that the rock formations truly represent. Our tour guide explained that the caverns were first explored and mapped in the 1960’s and have been under continual exploration and development since that time. According to the website it is the largest commercially operated cave system in Texas‚ though not the largest

Designer Case Studies – 3.5 Creativity and innovation can be developed in different ways and there are many starting points for design and making. A first- hand reference could be photographing natural forms and patterns as they occur outdoors. Structures‚ such as buildings‚ and the geometry found in everyday objects can provide inspiration. You could set up a still life of objects‚ or take a trip to a design museum and feel inspired to design from these sources. Starting points can also be secondary

Running Head: Eggshells used in chalk production Eggshell as an alternative source in chalk production Ryan Jason U. Joquico Lourdes School of Mandaluyong II-Blessed Andrew Hyacinth Longhin September 5‚ 2011 CHAPTER I INTRODUCTION Background of the Study The Research is about the effectiveness of eggshells as an alternative ingredient in chalk production. The study is very efficient in these days because many people are in need of chalk. The components of chalk are so

External Forces One and Two Weathering- is the process that changes solid rocks into sediments. There are four types of weathering water‚ wind‚ glaciers‚ and gravity Water is responsible for most weathering Wind moves sand-sized particles of rock through the air Glaciers move all sizes of sediment Gravity moves broken pieces of rock downslope Physical Weathering- involves the breaking down of rocks into situ without any change in the composition Freeze Thaw- when water seeps into the cracks and

Investigatory Project Presented to the Department of Science and Technology By: Coleen Sioson October 2012 A. Experiment Description In this investigatory project‚ we will use eggshells as an alternative ingredient in chalk production. The study is very efficient in these days because many people are in need of chalk especially the teachers because they use board chalks in school everyday.We noticed that the students and teachers consume many pieces of it‚ which is very expensive.

BARBADOS Barbados is made up pf over 85% coral limestone CLIMATE Tropical climate therefore the heat increases rates of chemical weathering and it promotes high biological activity such as the rapid decay and formation of humic acid DRAINAGE Barbados has a high drainage density and this allows for water to easily percolate through the coral limestone and this increases chemical weathering TOPOGRAPHY Flatlands - St Lucy A wide flat region stretching across the northern part of the island.

Depending on the materials‚ the rotary kiln falls into three types: clinker rotary kiln‚ limestone rotary kiln and cement rotary kiln. An experimental study of the calcination of limestone has been carried out in a highly instrumented pilot-scale rotary kiln. Local gas‚ solids‚ and wall temperatures and pct calcination have been measured under a range of operating conditions to determine the influence of limestone type‚ feed rate‚ rotational speed‚ inclination angle‚ and particle size on calcination
