why do some seeds need fire to germinate

, the planet s largest trees and among the oldest living things on EarthБmany of the largest are Бdepend on fire to help them reproduce. in this clip from. Some background from In the early 1960s, Dr. Richard Hartesveldt explored the connection between fire and sequoia regeneration. His small-scale prescribed fires followed nearly a century of fire suppression, and resulted in the germination of sequoia seeds and the recruitment of sequoia seedlings something that had not occurred in the absence of fire. Since those first experiments, researchers have further shown the benefits to sequoias from fire. has determined that low intensity surface fires swept through the big trees approximately every 5 to 15 years. Sequoias rely on fire to release most seeds from their cones, to expose bare

why do we need to study electronics

Electrical Electronic Engineering is a fascinating field, and one which could make your time at uni a challenging, enriching and rewarding experience. Just as the world needs its Doctors, Nurses and Teachers, Electrical Engineering is something which we simply couldn't do without. If you like the idea of creating electrical systems which could help millions of people on a day to day basis, like the systems used in phones, or computers, then read these reasons to study Electrical Electronic Engineering. P 1. Electrical Engineers have good Graduate Prospects As you can see on the, Graduate Prospects remain high even a bit lower down the table. Certainly in the top 10 institutions, Graduate Prospects are formidable when compared to some other subjects. This suggests a higher employability

 why do volcanoes occur at plate boundaries

why do volcanoes occur at plate boundaries

Volcanic activity occurs at two types of plate boundaries: mid-ocean ridges and subduction zones. At mid-ocean ridges, basaltic eruptions produce new sea-floor crust. These underwater eruptions don't produce big mountainous volcanoes, which is why they are often overlooked as the most volcanically active features on Earth. Commonly, basalt is erupted at mid-ocean ridges as blob-shaped "pillows. " These pillows form when basalt is suddenly quenched as it comes into contact with sea water. If you cut a pillow in half, you'll find a glassy rind around the outside, where the lava cooled so fast that it couldn't form any crystals. Inside the pillow will be a crystalline matrix of cooled basaltic lava. At subduction zones, volcanoes are created on the overriding plate as melt from the
