الإعجاز العلمى فى ( فإذا أنزلنا عليها الماء اهتزت )

[د/ عبد الرحمن]

و هذا رابط آخر للتأكيد على أن جزيئات التربة تتحرك فى الماء عندما يسقط المطر بما يعرف باسم حركة براون أو Brownian motion

7. Swelling and shrinkage: Some clay (soil colloids) such as smectites swell when wet and shrink when dry. After a prolonged dry spell, soils high in smectites (e.g. Vertisols) often are crises-crossed by wide, deep cracks, which at first allow rain to penetrate rapidly. Later, because of swelling, such soil is likely to close up and become much more impervious than one dominated by kaolinite, chlorite, or fine grained micas. Vermiculite is intermediate in its swelling and shrinking characteristics

و هو يتضح عن انتفاخ الطمى فى الماء و انكماشه إذا جف و هو ما يوافق الآية الكريمة التى تصف الأرض بأنها تربو إذا نزل عليها المطر

9. Brownian movement: When a suspension of colloidal particles is examined under a microscope the particles seem to oscillate. The oscillation is due to the collision of colloidal particles or molecules with those of the liquid in which they are suspended. Soil colloidal particles with those of water in which they are suspended are always in a constant state of motion. The smaller the particle, the more rapid is its movement.

و كما هو واضح تتحدث عن أن جزيئات الطمى تتحرك إذا وضعت فى ماء الحركة التعرف باسم حركة براون أو Brownian motion
