A sedimentation rate is common blood test that is used to detect and monitor inflammation in the body. The sedimentation rate is also called the erythrocyte sedimentation rate because it is a measure of the red blood cells (erythrocytes) sedimenting in a tube over a given period of time. Sedimentation rate is often abbreviated as sed rate or ESR. Although this test measures a general state of inflammation, it is not specific to what causes the inflammation. It is elevated in inflammatory diseases, including arthritis as well as in autoimmune diseases such as lupus.
Earth spins because of the way it was formed. Our Solar System formed about 4.6 billion years ago when a huge cloud of gas and dust started to collapse under its own gravity. As the cloud collapsed, it started to spin. Some of the material within this cloud gathered into swirling eddies and eventually formed into planets.
At the equator the Earth is spinning on its axis at a speed of about 1,038 miles (1,670 kilometres) an hour. Earth's spin or rotation is a relic of its origin as a hot, spinning mass when it was first formed. Earth science or geology is the science of the Earth.It is an organized study and body of knowledge about mountains, plains and oceans; about the history of life on Earth; and about the succession of physical events that have been (or are still) part of this history.1.t the equator the Earth is spinning on its axis at a speed of about 1,038 miles (1,670 kilometres) an hour.
