What political unit passed the Water Framework Directive?
The European Union passed the Water Framework Directive in 2000. It is a comprehensive piece of legislation aimed at protecting and improving the quality of water across Europe.
Why are non silicate minerals is economically important?
Non-silicate minerals are economically important because they often contain valuable elements such as metals (e.g., gold, silver, copper) that are used in industry, technology, and construction. These minerals are mined for their economic value, contributing to various industries and supporting economic growth. Additionally, some non-silicate minerals have unique properties that make them useful in specialized applications, further increasing their economic significance.
Something that has a large distance between its opposite sides or surfaces can be considered thick. Tend to be solid and not easily bent or broken.
Why did profesor lidenbrock go to the center of the earth?
Professor Lidenbrock went to the center of the Earth in the Jules Verne novel "Journey to the Center of the Earth" because he discovered a message hidden in an ancient manuscript that led him to believe an entrance to the Earth's core existed in a volcano in Iceland. He was driven by scientific curiosity and the desire to make a groundbreaking discovery.
What are the top 5 elements on the earth's surface?
The top five elements on Earth's surface are oxygen, silicon, aluminum, iron, and calcium. They are abundant in the Earth's crust and play key roles in the composition of rocks, minerals, and soils.
Is a rubber ducky more dense then water?
no beacause a rubber duck floats and if an object floats in water, is is less dense than the water if it sinks it is more dense

Is the earth experiencing a pole shift right now?
YES!!! It has always had a 'pole shift'.
If you look on any sophisticated map , there will be a key indicating true (Axial) North and Magnetic North.
The Magnetic North will have an indication on it showing it is increasing/decreasing by so much per year. So the magnetic pole is shifting.
Also, the true(axial) north is shifting too. This is because of 'Precession'. This is because the Earth spins on a daily basis, and the axis (Poles) counter spins much more slowly. So the poles are shifting.
NB Spin a gyro. Notice ,whilst spinning the gyro appears to 'wobble' , this is precession, and the Earth does exactly the same.

Where 6 months day 6 months night?
At the poles, such as the North and South Poles, there are regions where the sun remains above the horizon for about six months during summer, resulting in continuous daylight, followed by six months of darkness during winter. This phenomenon is known as polar day and polar night.
Which weathers faster feldspar or marble?
Marble weathers faster than feldspar because marble is more susceptible to chemical weathering due to its composition of calcium carbonate, which reacts easily with acidic rainwater. In comparison, feldspar is more resistant to weathering due to its hardness and chemical stability.
Do plant roots cause mechanical weathering?
Yes, plant roots can cause mechanical weathering by exerting pressure on rocks as they grow and expand, leading to the breakdown of the rock material. This process is known as root wedging and can contribute to the disintegration of rocks over time.
Is there a imaginary pole going through the earth call the equator?
Yes, the equator is an imaginary line that circles the Earth halfway between the North and South Poles. It divides the Earth into the Northern Hemisphere and the Southern Hemisphere and plays a crucial role in determining climates and seasons around the world.
How does the size of the sun compare to the size of the earth?
The sun is 695,500 km in radius, while the earth's radius is only 6378 km.
This means that if the sun was about as tall as a regular desk, the earth would be the size of a small paperclip. You could fit about 1,000,000 whole earths inside of the sun, (slightly more or less depending on how you arranged them). The sun is also very dense, and weighs 332,900 times as much as the earth.
In the related links section, you can find a to-scale picture of the sun next to the earth.
What are sudden disturbances in earth's magnetic field called?
Sudden disturbances in the Earth's magnetic field are called magnetic storms. These storms are typically caused by solar wind interacting with Earth's magnetosphere, resulting in fluctuations and disturbances in the magnetic field. Magnetic storms can affect a variety of technologies such as power grids, satellites, and communication systems.
Why does the Moon's gravity have a greater effect on earths oceans tides then the suns gravity?
-- The forces of gravity between two masses are inversely proportional to
the square of the distance between the masses, and directly proportional
to the product of the masses.
-- The sun is about 390 times as far from us as the moon is.
-- The square of 390 is 152,690.
-- So each little pellet of mass in the moon attracts each little pellet of water on
Earth 152,690 times as strongly as the same size pellet of solar mass does.
-- The sun has 27.08 million times as much mass as the moon has. So all the
pellets in the sun put together attract each little pellet of water on the Earth
27.08 million times as strongly as the whole moon would if it were at the same
distance from us as the sun is.
-- Put these two together, and you have 27.08 million times stronger, divided by
152,690 times weaker, = 177.4 times as much force in favor of the sun.
Surprise! The sun actually has a greater effect on the tides than the moon does.
What can natural resources be protected and managed through?
The first and the foremost thing needed for the protection of the natural resources is the awareness. we all are awared that natural resources are available in limited quantity and they are going to exhaust after a certain period. one side Govt. and other Environmental conservation agencies are talking about the conservation of natural resources and in the another way they are talking about the development of people and country with the exploitation of natural resources. it can be managed only if we change our attitude towards the environment.
How is continental lithosphere different from oceanic lithosphere?
Continental plates are thicker and less dense. Continental plates are mainly granitic in composition. Oceanic plates are mainly basaltic in composition. The rock of continental plates is on average, much older than the rock of the oceanic plates.
The oceanic plate underlies the oceans, and the continental plate makes up the land masses. Continental plates do not subduct at convergent plate boundaries.
How many people are there on earh?
As of 2021, there are approximately 7.9 billion people on Earth. The world's population continues to grow at a rate of about 1.1% per year.
What is the presence of water of earth?
71% percent of earth surface is occupied with water and all the living being contain water in their body also.
How does the Cryosphere affect the geosphere?
The area of Our one and only Earth that is frozen is It's Cryosphere; it represents just a portion of Earth's Geosphere, and as such is affected by any changes that occur within the Geosphere.
What impact do ocean currents have on the transfer of energy and climate?
Ocean currents play a crucial role in transferring heat energy around the planet, helping to regulate climate and temperature patterns. They can transport warm water from the equator towards the poles, influencing regional climate by moderating temperatures and affecting weather patterns. Changes in ocean currents can have significant impacts on global climate, potentially leading to shifts in weather patterns and temperatures.
Capillaries have a very small diameter ranging from 5 to 10 micrometers, which is about the size of a single red blood cell. This thin structure allows for efficient exchange of oxygen, carbon dioxide, nutrients, and waste products between the bloodstream and surrounding tissues.
What are the five earth systems?
The five Earth systems are the atmosphere (air), hydrosphere (water), lithosphere (land), biosphere (living organisms), and geosphere (rock and minerals). These systems interact and influence each other in various ways to shape the Earth's environment and ecosystems.
