The document describes the six main interconnected spheres that make up Earth's systems: the atmosphere, hydrosphere, lithosphere, biosphere, cryosphere, and anthrosphere. It explains each sphere in 1-2 paragraphs, highlighting what they include and their role. For example, it notes the atmosphere contains nitrogen, oxygen, argon and carbon dioxide and allows water transfer through the hydrologic cycle. Throughout, it emphasizes how the spheres are dependent on each other and how human activity can impact their interconnections.
The lithosphere is the solid shell of the planet Earth. That means the crust, plus the part of the upper mantle that behaves elastically on long timescales.
Water is the most precious gift of mother nature. Hydrology is the scientific study of the origin, occurrence, properties, distribution, and effects of water on the Earth’s surface, in the soil and in the underlying rocks, and also in the atmosphere. This module explain's the distribution of water in the global hydrosphere.

Earth's energy budget refers to the tracking of how much energy is flowing into and out of the Earth's climate, where the energy is going, and if the energy coming in balances with the energy going out. The Earth receives energy from the Sun, and it also reflects and radiates energy back into space. All of the energy that warms the atmosphere, oceans and land must be radiated back into space in order to maintain our current climate. If the amount of energy radiating back into space is decreased by even a very small amount, it can lead to warming. It is believed that increasing levels of carbon dioxide in the atmosphere has a 'greenhouse effect' of reducing the amount of energy radiated into space.

The Earth System
Earth is the third planet from the sun in our solar system. Earth orbits the sun in an elliptical (oval) path. Earth’s orbit is sometimes called the “Goldilocks zone.” Mercury and Venus travel too close to the sun to sustain life—they’re “too hot.” Planets beyond Earth travel too far from the sun—they’re “too cold.” But Earth is “just right.” (Note that there’s evidence that Mars—the Red Planet—once may have sustained microscopic life on its surface. However, conditions on the Red Planet no longer seem favorable.)
The term “Earth system” refers to the different processes and cycles that exist on the planet. All of these work together to sustain life. The four domains of the Earth system include the geosphere, the hydrosphere, the atmosphere, and the biosphere. Let’s quickly review each of these.
Layers of Earth
(NASA public domain image)
The geosphere refers to the solid portion of the planet. It includes the rocks and minerals that make up the continents as well as the ocean floor. It also includes structures within Earth, including the liquid mantle and the dense, solid, metallic core. Nonliving surface ground layers, such as desert sands and volcanic rock, are part of the geosphere.
The hydrosphere includes all the water on or near Earth’s surface. The oceans are the major component of the hydrosphere. They make up 97 percent of the Earth’s water. Glaciers and polar ice caps make up about 2 percent of the hydrosphere. Only about 1 percent of the hydrosphere is made up of the liquid freshwater found in ponds, streams, rivers, lakes, and underground water reservoirs (aquifers).
Aquifers are the main freshwater source in America’s “breadbasket” states of the Midwest and Great Plains. (“Breadbasket” states get their name from the volume of wheat, a primary ingredient in bread, grown there.) The hydrosphere extends several miles above the surface of the planet into the atmosphere, mainly in the form of water vapor.
Water vapor is water in its gaseous state. Precipitation is water released from the clouds. It may take the form of rain, freezing rain, sleet, snow, or hail. It’s part of the water cycle.

The atmosphere is the planet’s blanket. It allows living beings on the planet to breathe. It also protects us from the unfriendly features of the universe, such as meteors, cosmic radiation, and the effects of solar flares.
The atmosphere is made up of a variety of layers, as follows:
Earth’s Atmosphere
(NASA public domain image)
· The troposphere is the densest part of the atmosphere. It starts at Earth’s surface and extends upward from about 5 miles (in the higher or lower latitudes) to 9 miles (over the equatorial regions). Most of our weather takes place here.
· The stratosphere extends from the troposphere upward about 31 miles. The ozone layer, which protects the planet from solar ultraviolet radiation, is located in this region.
· The mesosph.

This article presents how planet Earth was born, how it operates and how it is protected from threats coming from outer space. In addition to showing how the Earth operates as a dynamic system, it shows how our planet will disappear completely when the Sun migrates out of Earth's orbit in about 1 billion years.
ANAMOLOUS SECONDARY GROWTH IN DICOT ROOTS.pptxRASHMI M G
Abnormal or anomalous secondary growth in plants. It defines secondary growth as an increase in plant girth due to vascular cambium or cork cambium. Anomalous secondary growth does not follow the normal pattern of a single vascular cambium producing xylem internally and phloem externally.
Nucleophilic Addition of carbonyl compounds.pptxSSR02
Nucleophilic addition is the most important reaction of carbonyls. Not just aldehydes and ketones, but also carboxylic acid derivatives in general.
Carbonyls undergo addition reactions with a large range of nucleophiles.
Comparing the relative basicity of the nucleophile and the product is extremely helpful in determining how reversible the addition reaction is. Reactions with Grignards and hydrides are irreversible. Reactions with weak bases like halides and carboxylates generally don’t happen.
Electronic effects (inductive effects, electron donation) have a large impact on reactivity.
Large groups adjacent to the carbonyl will slow the rate of reaction.
Neutral nucleophiles can also add to carbonyls, although their additions are generally slower and more reversible. Acid catalysis is sometimes employed to increase the rate of addition.

Observation of Io’s Resurfacing via Plume Deposition Using Ground-based Adapt...Sérgio Sacani
Since volcanic activity was first discovered on Io from Voyager images in 1979, changes
on Io’s surface have been monitored from both spacecraft and ground-based telescopes.
Here, we present the highest spatial resolution images of Io ever obtained from a groundbased telescope. These images, acquired by the SHARK-VIS instrument on the Large
Binocular Telescope, show evidence of a major resurfacing event on Io’s trailing hemisphere. When compared to the most recent spacecraft images, the SHARK-VIS images
show that a plume deposit from a powerful eruption at Pillan Patera has covered part
of the long-lived Pele plume deposit. Although this type of resurfacing event may be common on Io, few have been detected due to the rarity of spacecraft visits and the previously low spatial resolution available from Earth-based telescopes. The SHARK-VIS instrument ushers in a new era of high resolution imaging of Io’s surface using adaptive
optics at visible wavelengths.

DERIVATION OF MODIFIED BERNOULLI EQUATION WITH VISCOUS EFFECTS AND TERMINAL V...Wasswaderrick3
In this book, we use conservation of energy techniques on a fluid element to derive the Modified Bernoulli equation of flow with viscous or friction effects. We derive the general equation of flow/ velocity and then from this we derive the Pouiselle flow equation, the transition flow equation and the turbulent flow equation. In the situations where there are no viscous effects , the equation reduces to the Bernoulli equation. From experimental results, we are able to include other terms in the Bernoulli equation. We also look at cases where pressure gradients exist. We use the Modified Bernoulli equation to derive equations of flow rate for pipes of different cross sectional areas connected together. We also extend our techniques of energy conservation to a sphere falling in a viscous medium under the effect of gravity. We demonstrate Stokes equation of terminal velocity and turbulent flow equation. We look at a way of calculating the time taken for a body to fall in a viscous medium. We also look at the general equation of terminal velocity.
BREEDING METHODS FOR DISEASE RESISTANCE.pptxRASHMI M G
Plant breeding for disease resistance is a strategy to reduce crop losses caused by disease. Plants have an innate immune system that allows them to recognize pathogens and provide resistance. However, breeding for long-lasting resistance often involves combining multiple resistance genes
2. The Earth is certainly a fascinating place. There is no other planet like this truly
unique and one of a kind object. Our knowledge of its inner workings and the
systems that function within it continue to grow with each passing day. But as
things usually occur, the more answers we uncover, the more questions we have.
One of the greatest and most intriguing things about this planet is its
interconnected spheres (or systems).
These spheres describe all of the many great things that make this planet
habitable. It's through a study of these interconnected and related spheres that
we can begin to truly understand our impacts to the Earth and the environment.
This will give us a "big picture view" of how the natural processes and cycles of
Earth work (similar to a Life Cycle Assessment for a product) and how human
activity is changing them. The first concept to learn in Earth Systems Science is
the six main spheres of the planet.
3. Atmosphere – This is the gaseous layer of air that encloses the Earth. Air is a
mixture of gases made mostly of nitrogen (78.08%), oxygen (20.95%, Argon
(0.93%), and carbon dioxide (0.033%). The atmosphere allows water to be
transferred between the other spheres as part of the Hydrologic Cycle. The
atmosphere is subdivided into 5 smaller spheres.
The troposphere is the bottom most layer of the atmosphere. This layer is
defined by the fact that all weather, such as precipitation, occurs here. We
live in the troposphere.
The next layer of the atmosphere is the stratosphere. This is where most
of our commercial airplanes fly. It extends from a height of about 5 to 10
miles above Earth’s surface (varies with temperature and location) to a
maximum vertical height of 31 miles. This is also where our Ozone layer is.
4. The third layer of the atmosphere is the mesosphere. This layer extends
from 31 miles upward to about 53 miles upward. It is here where most
meteorites burn up.
The fourth layer of the atmosphere is the thermosphere. This layer
extends from about 53 miles upward to somewhere between 311 and 621
miles into space. It is in the layer that the space shuttle would orbit the
planet. The start of “space” also begins here at a vertical height of 62
miles above Earth’s surface.
The fifth and final layer of the atmosphere is the exosphere. This part of
the atmosphere is where atoms and molecules begin to drift freely. They
are far enough away from Earth to resist its pull of gravity.
5. Hydrosphere – The hydrosphere is the interconnected system of all of the
liquid water on this planet. The process of the hydrologic cycle such as
evapotranspiration, precipitation, and groundwater transport are all a part of
the hydrosphere. Humans have become a large part of the hydrosphere too. We
consume large quantities of water that has huge impacts on how this system
works. Water is stored in oceans, lakes, streams, and rivers.
Lithosphere - The lithosphere is the Earth's solid portion. This includes all of
the sediments that form the crust as well as the various layers of the Earth's
interior.
Biosphere – This is the sphere in which all living things are a part of. The
biosphere contains all of the plants, animals, and other living creatures that
exist in our world. This is the sphere that distinguishes our planet from other
planets.
6. Cryosphere – This is the system of the earth that includes all of the frozen, or
solid, water of the earth. This includes all snow, ice, glaciers, icebergs, and the
arctic climate. The Cryosphere is sort of like a sub sphere of the hydrosphere.
This sphere places an important roll in our global climate. It is also a key
indicator of climate changes such as global warming.
Anthrosphere – The anthrosphere is the system of humanity. This includes all of
the places and things we have built and constructed such as the roadways and
buildings in our cities or the farm fields in our rural towns. Every manmade
creation, as well as man himself is a part of the anthrosphere.
7. As you have probably already deduced, all of the spheres are interconnected. All
six spheres can exist in one particular location at any given moment in time.
The spheres are also dependent on each other. A change in one sphere will
result in a change in another. For example, volcanic activity can transfer water
from the lithosphere to the atmosphere.
Then the water is transferred into the biosphere when a field of corn soaks it up
after a good rain. Then the corn enters the anthrosphere where it is processed
for human consumption. After consumption, it will enter the lithosphere again.
So hopefully you can see that everything we do on this planet affects
something else (even if we can't see it, or the effect isn't noticed for years). You
can also imagine that as the anthrosphere grows, the cryosphere and biosphere
will shrink.
8. For people concerned with the environment, it is vitally important that they
understand the concepts of the interconnected spheres of the Earth.
