PLEASE HELP WILL GIVE BRAINLIEST!
Answer:
Divergent boundaries
Divergent boundaries occur along spreading centers where plates are moving apart and new crust is created by magma pushing up from the mantle. Picture two giant conveyor belts, facing each other but slowly moving in opposite directions as they transport newly formed oceanic crust away from the ridge crest.
Perhaps the best known of the divergent boundaries is the Mid-Atlantic Ridge. This submerged mountain range, which extends from the Arctic Ocean to beyond the southern tip of Africa, is but one segment of the global mid-ocean ridge system that encircles the Earth. The rate of spreading along the Mid-Atlantic Ridge averages about 2.5 centimeters per year (cm/yr), or 25 km in a million years. This rate may seem slow by human standards, but because this process has been going on for millions of years, it has resulted in plate movement of thousands of kilometers. Seafloor spreading over the past 100 to 200 million years has caused the Atlantic Ocean to grow from a tiny inlet of water between the continents of Europe, Africa, and the Americas into the vast ocean that exists today.
Convergent boundaries
The size of the Earth has not changed significantly during the past 600 million years, and very likely not since shortly after its formation 4.6 billion years ago. The Earth's unchanging size implies that the crust must be destroyed at about the same rate as it is being created, as Harry Hess surmised. Such destruction (recycling) of crust takes place along convergent boundaries where plates are moving toward each other, and sometimes one plate sinks (is subducted) under another. The location where sinking of a plate occurs is called a subduction zone.
The type of convergence -- called by some a very slow "collision" -- that takes place between plates depends on the kind of lithosphere involved. Convergence can occur between an oceanic and a largely continental plate, or between two largely oceanic plates, or between two largely continental plates.
Oceanic-continental convergence
If by magic we could pull a plug and drain the Pacific Ocean, we would see a most amazing sight -- a number of long narrow, curving trenches thousands of kilometers long and 8 to 10 km deep cutting into the ocean floor. Trenches are the deepest parts of the ocean floor and are created by subduction.
Continental-continental convergence
The Himalayan mountain range dramatically demonstrates one of the most visible and spectacular consequences of plate tectonics. When two continents meet head-on, neither is subducted because the continental rocks are relatively light and, like two colliding icebergs, resist downward motion. Instead, the crust tends to buckle and be pushed upward or sideways. The collision of India into Asia 50 million years ago caused the Indian and Eurasian Plates to crumple up along the collision zone. After the collision, the slow continuous convergence of these two plates over millions of years pushed up the Himalayas and the Tibetan Plateau to their present heights. Most of this growth occurred during the past 10 million years. The Himalayas, towering as high as 8,854 m above sea level, form the highest continental mountains in the world. Moreover, the neighboring Tibetan Plateau, at an average elevation of about 4,600 m, is higher than all the peaks in the Alps except for Mont Blanc and Monte Rosa, and is well above the summits of most mountains in the United States.
Two similar fans are operating in a room. Fan 1 makes a squeaking noise while running. Fan 2 is silent.
Which fan is more energy efficient?
a. Fan 1, because Fan 2 cannot convert energy into sound.
b. Fan 2, because the silence indicates there is no energy transfer going on in the fan.
c. Fan 1, because the noise indicates there is no energy transfer going on in the fan.
d. Fan 2, because Fan 1 converts some energy to sound.
Answer:
Fan 1, because Fan 2 cannot convert energy into sound.
Explanation:
When Two similar fans are operating in a room. Fan 1 makes a squeaking noise while running. Fan 2 is silent. Then Fan 2 has more energy efficiency because Fan 1 converts some energy into sound. Therefore correct answer is D.
What is energy ?Energy is nothing but the ability to do work. there are different energies in different form which are thermal energy, mechanical energy, electric energy and sound energy etc.
According to first law of thermodynamic, Energy neither be created nor be destroyed. it can only be transferred from one form into another form.
in case of Fan 1, Electric energy is given to it but it makes a squeaking noise while running. It means that it transfer some amount of total energy in sound energy and remaining for mechanical energy. Fan 1 can not transfer all the energy in the mechanical energy, there is loss in the energy in the form of sound.
in case of Fan 2, it is silent, it is converting all the electric energy into mechanical energy. there is no loss of energy. hence it is more energy efficient.
Hence option D is correct.

What are all the ways energy is transferred as the tea kettle is heated, the steam turns the turbine, and the lightbulb lights up?
Answer:
In a kettle, electrical energy is transformed into thermal energy.
Most energy is transferred into heat energy inside a lightbulb, thats why most ordinary electric lamps contain a thin metal filament that glows when electricity passes through it.
When the steam turn’s the turbine, it is turned into kintetic energy.

give real-world examples of how the body responds to stimuli.
Some real world examples of how the body responds to stimuli are:
External stimuli: something is coming at your face and you flinch or blink, you see a car coming at you so you dive out of the way, you are enjoying an activity and so your body releases dopamine.
Internal stimuli: you are hungry and signals respond to stimulus and send signals to your brain,
How does electricity turn into light in a common lightbulb?
A. Electricity strikes the metal particles of the filament in a lightbulb. Some of the metal particles become gases and turn into light.
B. Electricity cools down the filament in the bulb to a very low temperature. At that temperature, the metal becomes bright and gives off light.
C. Electricity heats up the filament in the bulb to a very high temperature. At that temperature, the metal becomes bright and gives off light.
D. Electricity strikes the metal particles of the filament in a lightbulb. Some of the metal particles are ripped off from the metal and turn into light.

Do you think seismographs predict earthquakes or measure earthquakes, explain your answer?
Seismographs measure earthquakes, but they do not predict them.
What is a sesimographs?A seismograph is an instrument that detects and records ground motion caused by seismic waves generated by earthquakes or other sources such as explosions or volcanic eruptions. When an earthquake occurs, seismic waves radiate out from the epicenter and cause vibrations in the ground. Seismographs detect these vibrations and record them as a seismogram, which shows the time, amplitude, and duration of the earthquake.
Seismologists can use the data from seismographs to determine the location, magnitude, and depth of an earthquake. This information can be used to assess the potential impact of the earthquake and help in the development of earthquake-resistant structures and emergency response plans. However, seismographs cannot predict when an earthquake will occur. Despite advances in earthquake science, the behavior of earthquakes remains unpredictable, and there is currently no reliable method for earthquake prediction.
