Continents split apart at divergent boundaries. Hot material rises, causing a bulge in the crust. The bulge splits when it's stretched, forming a rift valley. the rift valley widens, the floor sinks, and water fills it when it gets deep enough.
Trace of protein: You need to have a 24 h hour urine collection to see how much protein in your urine/day. Protein excretion by a diseased kidney is not constant, rather it is sporadic over 24 hours. That is why a 24 hour collection will tell you if your proteinuria is a problem or not.roteinuria: presence of protein in the urine is usually suggestive of underlying kidney disease. When the kidney filters get damaged the protein from blood tends to leak into the urine and causes further damage. most common causes are diabetes and high blood pressure.
Large molecules such as red blood cells and protein, also called albumin, stay in the blood. When your nephrons are damaged, albumin and other proteins leak into your urine. Urine dipstick tests and 24-hour urine collections check for protein in your urine. The presence of protein in your blood is abnormal. Urinary tract infections and diabetes can cause albumin to appear in your urine. Other conditions, such as heavy metal poisoning, bladder cancer, hypertension and systemic lupus erythematosus, can cause protein in the urine as well.
