1. What are the different ways tectonic plates move in relation to each other?

2. What landforms could be the result of converging plates? name a location where this occurs.

3. What landforms could be the result of diverging plates? Name a location where this occurs.

4. What major event could occur as the result of transforming plates? Name a location where this can occur.

5. if crust is constantly created at divergent boundaries, why isn't Earth getting larger?

Answers

Answer + Explanation:

1. The different ways tectonic plates move in relation to each other are:

convergent (where plates move into one another)

divergent (where plates move apart)

transform (where plates move sideways in relation to each other)

2. Convergent plate boundaries can result in:

earthquakes, volcanoes, and the formation of mountains.

The Himalaya Mountains are the result of convergent plate boundaries.

3. Landforms that are a result of divergent boundaries are rift valleys and mid-oceanic ridges.

Locations where this occurs are: Mid-Atlantic Ridge, Red Sea Rift, Baikal Rift Zone

, East African Rift, East Pacific Rise, Gakkel Ridge, Galapagos Rise, and Explorer Ridge.

4. Transforming plate boundaries results in shallow earthquakes, large lateral displacement of rock, and a broad zone of crustal deformation.

A location where this occurs is: San Andreas Fault in western California

Which situation is an example of heat transfer by radiation?

Answers

Answer:

This type of transfer takes place in a forced-air furnace and in weather systems, for example. Heat transfer by radiation occurs when microwaves, infrared radiation, visible light, or another form of electromagnetic radiation is emitted or absorbed. An obvious example is the warming of the Earth by the Sun.

Answer:

the heat from the hotter to the colder region. Some common examples of Radiation are Ultraviolet light from the sun, heat from a stove burner, visible light from a candle, x-rays from an x-ray machine. All life on Earth depends on the transfer of energy from the Sun, and this energy is transferred to the Earth over empty space.

Sound, earthquakes, and waves in water are mechanical waves because they require a physical ______________________ to transport energy.

Disturbance

Electromagnetic field

Location

Medium

Answers

Answer is disturbance

Sound, waves are all propagation of energy. Transport of this energy require a physical medium. Thus option D is correct.

What is mechanical waves?

Mechanical waves are a form of energy transfer by oscillation of matter and they require a medium to propagate. Sound wave is a longitudinal wave which is only passing through a medium of air. Air disturbance causes these sound waves.

Longitudinal waves are those where the direction of oscillation of matter is along the direction of propagation. Electromagnetic waves does not require a medium to travel.

Waves in water originates from the pressure difference in water earthquakes is caused by seismic waves which are transverse waves, where the oscillation of matter is perpendicular to the direction of propagation.

Hence, sound, earthquakes, and waves in water are mechanical waves because they require a physical medium.

Planets formed from small amounts of debris that were attracted together because of gravity.

D. Planets formed from small amounts of debris that were attracted together because of gravity.

A dense cloud of interstellar gas and dust formed our solar system roughly a billion years ago. A solar nebula—a whirling, swirling disk of material—was produced when this dust cloud collapsed. Gravity drew more and more material into the center. The sun was still forming and planets had not yet been created when the solar system was very young. The solar system consisted primarily of gas and dust.

How does hot object produce heat?

The hot objects create hot air producing heat.
Movement of the hot object creates heat.
Molecules in the hot objects create friction to produce heat energy.
Heat is absorbed the object from the air around it.

Answers

The object can creat heat from energy and friction but in some cases that’s not the case.

When objects are heated, the movement between the particles of the matter increases. As a result, particles move and vibrate more faster. When this happens, the heat can be transferred by vibrations between particles. Hope this is correct. If yes, please give me the brainliest
