What is solar wind?

चित्र
What is solar wind? How do charged particles ejected from the Sun affect Earth’s magnetic field? Solar winds move at a speed of 400 kilometers (250 mi) per second from the Sun. Corona's intense heat - The outermost part of the Sun's atmosphere raises the particles to such a level that the Sun's gravitational field can no longer hold onto them and they escape into space. The strength of solar wind varies, which is capable of disrupting space weather technology, such as the Global Positioning System (GPS) satellite.

What causes red tides ?

What  causes red tides? Why crimson seas are not as unbelievable a sight as you might first think.... A red tide is the rapid accumulation of a mass of aquatic algae, made up of mobile single-celled microbes, known as dinoflagellates - meaning the nature of tail-like projections spreading them through water. Due to 'whipping whip'. Algae grow, or blossom, more rapidly than usual to consume more nutrients that have suddenly increased from the cool depths of the ocean below. The red color is down to the presence of a certain species of dinoflagellate, or phytoplankton. With more abundant diatom algae, dinoflagellates make up the majority of the plankton of the ocean. Despite the rather staggering appearance of a sea that has turned red, many algal flowers are actually completely harmless. However, you should not consume seafood after red tide as some phytoplankton may release harmful substances into the water. Some dinoflagellates can produce toxins when eaten ...

World largest seal The name of the world's largest seal is SOUTHERN ELEPHANT SEAL This seal is also called BEACH BULLDOZER. The largest carnivore that breeds on land is ten times heavier than the male southern elephant seal polar bear. Males also weigh five times more than females. Elephants spend up to eight months in the open sea, traveling large distances in search of food. During a fishing dive, they can hold their breath for up to two hours - the longest for any marine mammal. SIZE:- 6½–20 ft (2–6 m) long; 790–11,025 lb (360–5,000 kg) in weight (males much longer and heavier than females) HABITAT :-Stony beaches and adjoining seas. LOCATION:-  Islands around the Antarctic and southern tip of South America. DIET :-   Fishes and squid. When the elephant seal dips in cold water, their heart rate decreases to circulate blood around vital organs. This dive reflex also occurs in humans, but is less effective.“At sea, elephant...
