The hydrosphere consists of all water on Earth, including oceans, seas, rivers, lakes, ice caps, groundwater, and water vapor. Most water is saltwater in the oceans, while freshwater exists on land in glaciers, groundwater, lakes, and rivers. Water moves through the hydrosphere in the water cycle of evaporation, condensation, and precipitation. Ocean currents distribute heat around the globe and influence climate.
In terms of biomass, the greatest migration in the world is the migration of Zooplankton .
Zooplankton migration is different because it moves up and down through the ocean's depths rather than traversing a landscape.
Fins are the most distinctive morphological features of fish and they plays a predominant role for locomotion of fish under the water. It is important to know how many kinds of fins are present and their precise functions.
Freshwater ecosystems are a subset of Earth's aquatic ecosystems. They include lakes and ponds, rivers, streams and springs, and wetlands. They can be contrasted with marine ecosystems, which have a larger salt content. This module explains the characteristics of aquatic ecosystems-freshwater ones.

Lakes and ponds are bodies of relatively still, or standing, water.
Although no definite size distinguishes a lake from a pond, lakes generally are larger and deeper than ponds.
Water enters lakes from streams and rivers, by rain or snow falling on or near the depression, and from groundwater.
Studying the geomorphology of lakes is a part of earth science studies. The presence of a lake, in any region, greatly influences the life of the people, living adjacent to it. There are several kinds of lakes in the world. Their characteristics are explained in this module.
Migration in fish including different types of movements, types of migration, physiological changes during migration and challenges during navigation is shared in the presentation. it is useful for the students studying ichthyology at PG level.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Synthetic Fiber Construction in lab .pptxPavel ( NSTU)
Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives.

1. The hydrosphere
The hydrosphere is all the water on the
planet. It is made up of oceans, rivers, seas,
lakes, glaciers, groundwater and water vapour
(clouds)
Water cycle 1. Evaporation: water evaporates.
2. Condensation: clouds formation.
3. Precipitation. Rain from clouds.
2.
3. Hydrosphere
Saltwater (97% of Earth), in oceans and seas.
- Salinity (amount of salt). Higher in hot and closed
seas.
- Temperature: higher in the surface, colder in the
deep.
- Denser than fresh water.
Fresh water (3%), on continents and islands.
- Most of it is at polar regions and glaciers.
- Some groundwater.
- Only al ittle in water vapour and lakes or rivers.
4. Oceans and seas.
Seas are oceanic waters close to
continents. They are not as deep as
oceans. Some are part of the ocean, other
are connected through narrow straits.
Some are interior.
Oceans are vast masses of saltwater
separating the continents. They cover a
large proportion of the Earth’s surface.
5. Some seas are extremely
salty, because of evaporation
or human explotation.
Life is difficult to find
there.
6. The Aral Sea is an
Example of a natural disaster
Provoked by human hand.
Overexplotation of rivers led
To the drying out of the sea.
11. Main ocean currents.
Ocean currents are large masses of water moving across the ocean.
They are warm and cold currents, and they move because of their differences
In density, salinity and temperature.
12. Currents and climate.
Newfoundland (Terranova, Canada) Brittany (Bretaña, France)
Temperature of ocean currents has a strong influence on climate. Brittany and
Terranova are at the very same latitude; however, temperature differences are
Higher than 10 degrees during winter.
13. Rivers: flowing currents of water
that
Stages of a river:
-Upper course: flows rapidly, with river valleys.
-Middle course: meandres.
-Lower course: river flows slowly, river mouth.
Flow will be determined by rainfall and soil.
14. The rapid flow erodes easily the bedrock
And creates sharp valleys(Los Pilones, Jerte)
UPPER COURSE OF A RIVER
15. Sand sediments on the lower
Course of river Tietar, tributary
of river Tajo (Casatejada,
Cáceres)
LOWER COURSE
