This lesson discusses the causes and effects of tropical storms like hurricanes. It will teach students to recognize and categorize different hurricane effects. Students will debate whether primary effects from direct winds and rain, or secondary effects further removed are worse. The lesson also explores how developed and developing countries are differently affected through case studies. As an assessment, students will research a past hurricane for homework.
Weather and storms are influenced by air masses and fronts. Air masses are large bodies of air that are classified by their source region (polar or tropical) and surface (continental or maritime). Fronts are boundaries between differing air masses. Thunderstorms develop through strong updrafts and produce lightning and thunder. Other storms include hurricanes, which form over warm ocean waters, and tornadoes, which are rotating columns of air. The ozone layer protects the Earth by absorbing UV radiation but is depleted by CFC emissions. El Niño is a phenomenon associated with extreme climate shifts.

Presentation On Winds,Storms, & Cyclones....Sourav Shaw
This is the best & wonderful presentation for the students who gets projects in school,colleges on winds,storms & cyclones.This presentation makes you easier to submit your project within the time limits.It shall may saves your time.
The document provides information about different types of winds and storms like cyclones, thunderstorms, tornadoes, and wind. It includes a student's name, class, roll number, and science group. The document then discusses learning objectives, textbook information, and exercises related to these atmospheric phenomena. Examples of how cyclones form and their destructive impacts are provided. Safety precautions for thunderstorms and explanations for various natural phenomena are also summarized.
This document lists the colors of the rainbow in order from R to V, spelling out ROY G BIV, and then lists each color with multiple exclamation points. It provides the order and names of the colors that make up a rainbow.
The document discusses the rainbow, noting that it appears when it rains and the sun is shining. It lists the 7 colors of the rainbow as red, orange, yellow, green, blue, indigo, and violet.
The document discusses how rainbows are formed. Rainbows are an optical phenomenon that occurs naturally in the Earth's atmosphere when sunlight interacts with water droplets, typically in the sky after it rains. The colors of the rainbow - red, orange, yellow, green, blue, indigo, and violet - correspond to the different wavelengths of light. Red appears outermost in the rainbow because it has the longest wavelength. A rainbow forms when sunlight enters and reflects off the inside surfaces of raindrops, undergoing one internal reflection and refracting at two surfaces before leaving the raindrop and reaching the observer's eye.
Thunderstorms develop frequently in hot, humid areas like India due to rising temperatures that produce strong upward winds carrying water droplets. These droplets freeze and fall, creating lightning and sound as they interact with the rising air in a thunderstorm. Cyclones form through a complex process where cloud formation releases heat into the atmosphere, warming the air and causing it to rise and the pressure to drop. This cycle draws in more air and forms a low pressure system with very high winds revolving around it, creating a cyclone. Cyclones can be very destructive with strong winds and waves that damage infrastructure and increase flooding.
Tropical storms form over warm ocean waters with temperatures of at least 27°C. Low air pressure and winds up to 175 mph are characteristics of these storms. When tropical storms make landfall, they can have devastating primary effects like strong winds, heavy rain, and storm surges, as well as secondary effects like flooding, infrastructure damage, and loss of life.
This document is a student project on winds, storms and cyclones. It contains sections that define and describe different types of winds like trade winds and monsoons. It also discusses natural disasters caused by severe weather like floods, earthquakes and tsunamis. Sections are included on air pressure, wind speed, how air expands when heated, wind currents and thunderstorms. The document finishes with descriptions of cyclones, tornadoes and precautions to take during severe storms.
Maybe sometimes we was looking a beautiful rainbow in the sky and surely there was someone who think about how rainbow is formed. In this presentation, we will know it could happened in the sky. Let's check it out!
Cirrus clouds are very wispy and high up around 20,000 feet. They are usually white and not associated with rain. Cumulus clouds are the puffy clouds seen around 3,000 feet up on sunny days. Cumulonimbus clouds produce thunderstorms, lightning, tornadoes and bad weather around 1,000 feet up. They can flatten at the top into an anvil shape. Stratus clouds cover the whole sky in a fog-like formation up to 6,000 feet and sometimes produce light drizzle or sprinkles while appearing grey.
Structure and Composition of the Atmospherebeaudry2011
The atmosphere is composed of gases, water droplets, and particles surrounding Earth. It has four main layers - the troposphere, stratosphere, mesosphere, and thermosphere - each decreasing or increasing in temperature with altitude. The troposphere is where weather occurs, extending 8-16km high. Above is the stratosphere where temperatures increase with little weather, then the mesosphere where temperatures decrease again up to 80km. The thermosphere is the outermost layer with increasing temperatures from 80km high. The atmosphere composition consists primarily of nitrogen, oxygen, argon, and trace gases. Water vapor is the most abundant variable gas.
The document discusses the four main systems that make up Earth: the atmosphere, hydrosphere, biosphere, and geosphere. It focuses on describing the layers of the atmosphere, including the exosphere, thermosphere, mesosphere, stratosphere, and troposphere. The troposphere contains most of the weather and clouds and temperatures decrease with increased altitude. The stratosphere contains ozone that absorbs UV radiation. The mesosphere is the coldest part while the thermosphere reaches temperatures over 1,700°C and protects the Earth from radiation.
The document summarizes the four main layers of Earth's atmosphere:
1) The troposphere, the lowest layer where weather occurs and temperatures decrease with altitude. Most water vapor and clouds are found here.
2) The stratosphere, which contains the ozone layer that absorbs ultraviolet light. Temperature increases with altitude in this layer.
3) The mesosphere, where meteorites burn up before reaching Earth's surface. Temperatures decrease with altitude in this layer.
4) The thermosphere, the uppermost layer where the temperatures sharply increase with altitude and the aurora occurs. Some satellites orbit within the thermosphere.
The document describes a proposed new data storage technology called "Rainbow Technology" that claims to be able to store up to 450 GB of data on an ordinary sheet of paper. It would represent data using colored geometric shapes rather than binary and could store around 2.7 GB per square inch when printed at high resolution. However, experts are skeptical because the claimed storage densities would require unprecedented compression or capabilities beyond current printing and scanning technologies. If proven, Rainbow Technology could provide an extremely low-cost and environmentally friendly alternative to DVDs and hard drives.
Tropical storms form over warm tropical oceans between 5 and 20 degrees north and south latitude. They require warm sea surface temperatures of 26 degrees C or more and generally occur in late summer and early autumn. Hurricane Katrina formed in late August 2005 and rapidly intensified into a category 5 hurricane over the Gulf of Mexico before making landfall and causing catastrophic damage, especially in New Orleans. Katrina was one of the costliest and deadliest hurricanes in U.S. history, resulting in over 1,800 deaths and over $150 billion in damages.
The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive functioning. Exercise boosts blood flow, releases endorphins, and promotes changes in the brain which help regulate emotions and stress levels.
