TYPES OF WEATHERING
WEATHER CAN EFFECT THE EARTHS LANDFORMS DRASTICALLY. THESE ARE JUST SOME OF ITS AFFECTS.
A STEM CAREER THAT WOULD STUDY WHAT WEATHER DOES WOULD BE:
A STEM CAREER THAT WOULD STUDY EARTHS LANDFORMS WOULD BE:
THESE ARE JUST SOME, OF THE STEM CAREERS THAT RELATE TO WEATHER/LANDFORMS.
METEOROLOGIST- THEY STUDY THE WEATHER THAT HAS OCCURRED AND MAY HAPPEN THEY USE THIS INFORMATION TO DETERMINE WHAT THESE WEATHER CONDITION CAN DO IN THE FUTURE. THE SKILLS THEY NEED ARE SCIENCE COURSES, MATH AND KNOWLEDGE OF TECHNOLOGY.
GEOSCIENCTIST-STUDIES THE EARTHS SUCH AS ITS STRUCTURE AND PHYSICAL FORM. THEY ALSO STUDIE HOW ITS FORM CAN AFFEC ALL ORGANISMS.
CARTOGRAPHY-THIS JOB IS WHERE YO PRACTICE OR DRAW MAPS FOR A JOB
STATISTIANTHEY PROVIDE TRUSTWORTHY DATA, THEY ANALYZE DATA TO MAKE ITS MEANING CLEAR, AND THEY DRAW PRACTICAL CONCLUSIONS FROM DATA.
HURRICANES- They can decimate landforms on some islands and coastlines. They also shape the coastline. Storm surges, wind, tornadoes, and flooding all come with the destructive force of a hurricane.
DROUGHTS- usually occur in hot dry areas of land. In most cases the area is dry because there is very minimal rainfall. The rain that falls will be absorbed into the ground or blown away by the dry air that moves along the ground. Droughts are very bad and can last for years, and it changes the way we live.
GLACIERS can cause damage to mountains by sliding down them. Glaciers not only transport material as they move, but they also sculpt and carve away the land beneath them. They can drastically change our earths form. Over many years the form can change completely.
WEATHER CHANGES EVERYTHING
Chemical Weathering- when a rock material is changed into a different substance by reacting with a chemical.
Mechanical Weathering- Is when you break the rock by using force (i.e. scratching, chipping)
Frost Action- Water seeps into small cracks in rocks. When the water freezes it expands creating great pressure. The crack widens and allows water to seep deeper into the rock.
Abrasion- rubbing against other rocks
Exfoliation- Rocks formed deep in the earth at a high pressure. When the pressure is released the rock expands and cracks. This may also be caused by the heating and cooling of rocks during weather conditions.
Plant Action- Tiny root hairs seek out small cracks and pits in the rock. Once the root hairs find a place, they grow and expand. The expansion causes great pressure and cracks the rocks.
Oxidation- Oxygen in the atmosphere chemically reacts with minerals.
Water- Minerals are dissolved in water.
Acid- Carbonic Acid- Co2 dissolves in rain water creating a weak acid. Acid Rain- Sulfur Dioxide in the atmosphere dissolves in rain water forming a strong acid (sulfuric acid)The rates of weathering will be influenced by: The amount of surface area exposed, Mineral Composition, and Climatic Conditions.
