How does density play a part in convection currents? Explain.

(I NEED THE ANSWER ASAP)

Answers

Answer 1

Answer:

Convection is heat transfer due to a density differential within a fluid

Example:

The current begins when the air over the hot sand is heated and begins to rise because of its lowered density. Air from above the ocean is colder and more dense. This cooler air takes the place of the rising hot air from over the sand

the defense between an earthquake's focus and its epicenter.

Answers

Answer: The focus is the place inside Earth's crust where an earthquake originates. The point on the Earth's surface directly above the focus is the epicenter. The epicenter is the point on the surface above the focus, the place on the surface that would receive the most intense vibrations.

Explanation: Hope it helps <3

The focus is the point within the earth where seismic waves originate; it is centered on the part of the fault that has the greatest movement. The epicenter is on the earth's surface directly above the focus.

Which feature of the ocean floor is observed more than any other feature?

Which ocean floor feature is responsible for creating the largest mountain ranges in the world?

Which two ocean floor features are found most closely to the ocean shore?

Which ocean floor feature is responsible for creating new land? Which is responsible for destroying land?

Answers

Answer:

In fact, the tallest mountains and deepest canyons are found on the ocean floor; far taller and deeper than any landforms found on the continents.

Rising up from the abyssal plain, you would encounter the mid-ocean ridge, an underwater mountain range, over 40,000 miles long, rising to an average depth of 8,000 feet. Tracing their way around the global ocean, this system of underwater volcanoes forms the longest mountain range on Earth.

Underwater landforms · Continental shelf Abyssal plains Mid-ocean ridge Ocean trenches Plate tectonics and the ocean floor Hydrography.

Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense.

At the deep-sea trenches, two plates converge, with one plate sliding down under the other into the mantle where it is melted. Thus, for each segment of new ocean floor created at the ridges, an equal amount of old oceanic crust is destroyed at the trenches, or so-called subduction zones.

What type of energy conversion happens when you draw a picture on the floor?
a. Chemical to thermal to electrical. b. Thermal to mechanical to chemical.
c. Mechanical to chemical to thermal. d. Chemical to mechanical to thermal.

Answers

Answer:

B.

Explanation:

Ur welcome

When a picture is drawn on the floor, chemical energy is converted to mechanical energy and then to thermal energy.

What is thermal energy?

Thermal energy is defined as a type of energy which is contained inside a system and is responsible for temperature rise.Heat is a type of thermal energy.It is concerned with the first law of thermodynamics.

Thermal energy arises as a result of  friction and drag.It includes the internal energy or enthalpy of a body of matter and radiation.It is related to internal energy and heat .It arises when a substance has  molecules or atoms which are vibrating faster.

These vibrating molecules and atoms collide with each other and as a result of which heat is generated in a substance , more the collision of particles , higher is the thermal energy.

the formula is E = P x t

Answers

The battery doesn't 'use' power.  The battery produces the power that all the other electrical devices use.

If the starter motor is using 2,520 watts, then the battery is producing energy at the rate of 2,520 watts.  That means 2,520 Joules of energy every second.

Thanks for giving us the formula.

E = P x t

Energy = Power x Time

Energy = (2,520 watts) x (1 second)

Energy = 2,520 Joules
