Use a Ruler to Weigh Your Fish content. For panfish, bass, trout, pike, muskie and walleye. Yes, it is possible to get an approximate weight for many species of fish by measuring their lengths. To estimate the weight of your catch, measure the fish's total length - from tail to the mouth - then refer to the appropriate table below.

Since the Sun is a ball of gas, this is not a solid surface but is actually a layer about 100 km thick (very, very, thin compared to the 700,000 km radius of the Sun).ince the Sun is a ball of gas, this is not a solid surface but is actually a layer about 100 km thick (very, very, thin compared to the 700,000 km radius of the Sun).
The number of sunspots you can count on the Sun's surface is not always the same, but varies over time. Solar activity is directly related to the frequency of sunspots. Here is a plot showing the number of sun spots since 1995: ROTATION: The sun does not rotate as a rigid body. It is a gas from its outermost layers down to its centre. The equatorial region of the photosphere rotates faster than do regions at higher and lower latitudes. This is called differential rotation. The differential rotation of the Sun's latitudes causes its magnetic field lines to become twisted together over time, causing magnetic field loops to erupt from the Sun's surface and trigger the formation of the Sun's dramatic sunspots and solar prominences.
