A wave that forms a large curl?
A wave that forms a large curl is typically known as a barrel or a tube. This type of wave is often sought after by surfers for its thrilling and challenging ride, as they can ride inside the hollow part of the wave as it breaks.
What are the inner and outer core composed of?
the inner core:
The inner core of the earth, its innermost hottest part as detected by seismological studies, is a primarily solid ball about 1,220 km (760 mi) in radius, or about 70% that of the moon. It is believed to consist of aniron nickel alloy, and may have a temperature similar to the sun's surface, approximately 5700 K (5430 °C).
the outer core:
The outer core of the earth is a liquid layer about 2,266 km (1,408 mi) kilometers thick composed of iron and nickel which lies above the Earth's solid inner core and below its mantle. Its outer boundary lies 2,890 km (1,800 mi) beneath the Earth's surface. The transition between the inner core and outer core is located approximately 5,150 km (3,200 mi) beneath the Earth's surface
How do you xxplain how active solar collectors work?
the main principal is photoelectric effect.....when the incident light absorbed on the surface of solar cell it generates electron-hole pair. which then generates the current. As our cell acts as P-N junction diode
photovoltaics (PV) are the direct conversion of sunlight into electrical power.Let's take a look at what a solar PV system comprises of, then we'll explain how the solar panels work.Solar Power Generation Systems begin with the solar module. Solar modules capture solar energy and generate direct current (DC) electricity. Inverters (power conditioners) convert DC into AC (alternating current) to run many common appliances and equipment.
Photovoltaic means electricity from light.
A solar PV system uses the natural energy from daylight in the form of solar radiation to generate electricity. This is different technology to solar thermal systems used for heating and hot water.
A charge is placed across the solar cell and as the energy from the sun hits the silicon, an electron is released from the atom. Due to the charge across the solar cell, this electron then flows towards the positive layer. Once you have an electron flow, a current is generated. This direct current is converted by an inverter in the system to an alternating current (AC) at the same level as the national grid.
What is a current of air called?
A current of air is commonly referred to as wind. It is the movement of air from high pressure to low pressure areas caused by the sun heating the Earth's surface unevenly.
The inner core of the earth is extremely hot and is probably solid?
Yes, the inner core of the Earth is estimated to have temperatures reaching up to 5,700°C (10,300°F). Despite these high temperatures, the inner core is believed to be solid due to the immense pressure that exists in the Earth's core.
For over two thousand years the method of drawing conclusions was based upon what?
For over two thousand years, the method of drawing conclusions was based upon deductive reasoning, which involves using general principles to reach specific conclusions. This method was popularized by philosophers like Aristotle and has been widely used in disciplines such as mathematics, philosophy, and science.
About how many elements make up everything on earth?
There are about 118 known elements that make up everything on Earth, with the most common elements being oxygen, carbon, hydrogen, and nitrogen. These elements combine in various ways to form different compounds and substances found in nature.
What is the depositional environment of gyprock?
Gypsum, the mineral that makes up drywall or gyprock, is commonly formed in marine environments where evaporation causes the concentration of dissolved calcium and sulfate ions in seawater, leading to gypsum precipitation. This process typically occurs in arid or semi-arid regions where evaporation rates are high compared to water input.
What two things are necessary for foliation to form in a metamorphic rock?
Directional pressure and differential stress are necessary for foliation to form in a metamorphic rock. Directional pressure causes minerals to align in the direction of the applied pressure, while differential stress leads to the segregation and elongation of mineral grains, resulting in the development of a foliated texture.
What is between electrons and the nucleus?
There is electron charge (and mass) everywhere inside the atom. It is not empty space.
There is electronic charge density in the entire volume of an atom. The electrons are said to orbit the nucleus, but that is a short hand description of reality. Reality is described by quantum mechanics and the representation of the location of the electrons is more like a diffuse cloud throughout the atom.
Empty space. Nothing.
Nothing. Empty space.
Nothing between the electrons and the nucleus is nothing
99.9% of that space has no matter in it
How are sandstone and conglomerate alike?
Sandstone and conglomerate are both sedimentary rocks composed of grains of sand. The primary difference between them is that conglomerate contains larger grains, typically pebbles or cobbles, embedded within a matrix of sand and mud. Both rocks are formed through the process of sedimentation and cementation.
Other factors that influence the rate of warming of a particular spot on Earth's surface include proximity to large bodies of water, urbanization and the urban heat island effect, elevation, land cover changes, cloud cover, and atmospheric circulation patterns. Additionally, factors such as albedo, greenhouse gas concentrations, and local weather patterns can also play a role in determining the rate of warming in a specific area.
At the march equnox what season starts in the northern hemisphere?
In the Northern Hemisphere, the spring season starts during the March equinox. This is when the tilt of Earth's axis is inclined neither away from nor towards the Sun, resulting in nearly equal hours of daylight and darkness.
Explain what type of stress in the crust results in the formation of folded mountains?
Folded mountains are the result of compression stress in the earth's crust. This is a movement of plates that presses together or squeezes Earth's crust and is also known as convergent boundary.
What direction can be measured using what instrument?
Direction can be measured using a compass, which points towards the Earth's magnetic poles. This instrument uses the Earth's magnetic field to determine north, south, east, and west directions.
What is the chemical formula for ca and co3?
The chemical formula for calcium is Ca and the chemical formula for carbonate is CO3. When combined, they form calcium carbonate with the chemical formula CaCO3.
What is the density of copper if the volume of a sample is 30cm cubed and the mass is 267g?
The copper's density is 8.9 g/cm3
What kind of context clue provides the meaning of a word directly in the sentence?
A definition context clue provides the meaning of a word directly in the sentence by paraphrasing or explaining the unfamiliar word or phrase. This type of clue can help readers understand the meaning without needing to look it up in a dictionary.
If you wanted to go southeast How would the compass be postitioned?
Assume for the sake of the illustration that the compass' N pointer is pointing to true north. Facing due south and holding the compass as you ordinarily would, the N pointer would be pointing straight to your spine. If you turn to the left by 45 degrees (to the south east) the N pointer will, relatively speaking, 'turn' to the left by 45 degrees; it will be pointing to your left side, or possibly right past you on the left.
How did early photosynthetic bacteria change earth?
Early photosynthetic bacteria changed Earth by producing oxygen as a byproduct of photosynthesis, which gradually built up in the atmosphere and led to the Great Oxidation Event around 2.4 billion years ago. This increase in atmospheric oxygen had a profound impact on the evolution of life on Earth, eventually paving the way for more complex organisms to thrive.
Can water cause physical weathering?
Yes, water can cause physical weathering through processes such as freeze-thaw action and hydraulic action. In freeze-thaw action, water seeps into cracks in rocks, freezes, expands, and causes the rock to break apart. Hydraulic action occurs when fast-moving water erodes and physically breaks down rocks over time.
What is the range of density within the inner core?
The inner core was discovered in 1936 by Inge Lehmann and is generally believed to be composed primarily of iron and some nickel. Its estimated density is between 12.6 to 13.0 grams to cubic centimeters.
Slumping occurs when a mass of material, like soil or rock, becomes unstable and moves downslope due to the force of gravity. Factors such as heavy rainfall, erosion, or human activities can weaken the stability of the material, leading to slumping. The material typically moves as a coherent mass along a curved surface, creating a distinctive landform feature.
"Fossil fumes" typically refer to the emissions produced by burning fossil fuels such as gasoline, diesel, and coal. These fumes contain pollutants like carbon dioxide, sulfur dioxide, and nitrogen oxides that can contribute to air pollution and climate change.
