Do convection currents of thermal energy form in Earth’s crust?

Biology

Ket [755]2 years ago
3 0
The Earth's crust is broken up into pieces called plates. The crust moves because of movements deep inside the earth. Heat rising and falling inside the mantle creates convection currents generated by radioactive decay in the core. Earth's solid crust acts as a heat insulator for the hot interior of the planet. ... Tremendous heat and pressure within the earth cause the hot magma to flow in convection currents. These currents cause the movement of the tectonic plates that make up the earth's crust. Convection currents are the result of differential heating. Lighter (less dense), warm material rises while heavier (more dense) cool material sinks. It is this movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth. Magma in the Earth's mantle moves in convection currents. The hot core heats the material above it, causing it to rise toward the crust, where it cools. The heat comes from the intense pressure on the rock, combined with the energy released from natural radioactive decay of elements. Description Magma or magma, meaning in Arabic, magma, magma, or magma, which is a mixture of fused silicon materials, or in other words with. Magma forms under the Earth's crust or other layers of the Earth.

The table below shows the dimensions of two colored cubes.
Lelechka [254]

Answer: The correct answer is black because the product of its side and mass is lower.

Explanation: Density of a substance is defined as the mount of matter that can be stored in a given volume.

Mathematically,

Density=\frac{Mass}{volume}

As, density is inversely proportional to the volume of the substance.

The substance will be more denser if it has less volume and it will be less denser if the volume is more.

We are given two cubes having different sides.

Volume of the cube is calculated by using the formula:

V=a^3

where, a = side of the cube.

Black: The side of this cube is 2 and volume will be = 2^3=8cm^3

Yellow: The side of this cube is 3 and volume will be = 3^3=27cm^3


As, the volume of black cube is less. So, this cube will be more denser.

Density of black cube: \frac{48}{8}=6g/cm^3

Density of Yellow Cube: \frac{135}{27}=5g/cm^3

Hence, black cube will be more denser  because the product of its side and mass is lower.

What are the functions of micronucleus and macronucleus in paramecium?
Ostrovityanka [42]
The macronucleus is the larger elipse-shaped nucleus and takes care of functions like respiration and digestion. In contrast to this, the smaller micronucleus is only involved in cell division or reproduction.

Define the following terms with examples:
Mashcka [7]

1) Chordata=A chordate is an animal of the phylum Chordata. All chordates possess 5 synapomorphies, or primary characteristics, at some point during their larval or adulthood stages that distinguish them from all other taxa

2) Vertebrates=vertebrate, also called Craniata, any animal of the subphylum Vertebrata, the predominant subphylum of the phylum Chordata. The vertebrates are also characterized by a muscular system consisting primarily of bilaterally paired masses and a central nervous system partly enclosed within the backbone.

3)Invertebrates=Invertebrates are animals that neither possess nor develop a vertebral column, derived from the notochord. This includes all animals apart from the chordate subphylum Vertebrata. Familiar examples of invertebrates include arthropods, mollusks, annelid, and cnidarians.

4) Poikilothermic animals=A poikilotherm is an animal whose internal temperature varies considerably. Poikilotherms have to survive and adapt to environmental stress.

5) Homeothermic animals=The term homeothermic refers to the warm-blooded animals which have constant and relatively higher temperature. They are animals which can maintain their internal body temperature. Complete answer: Homeothermic animals are warm-blooded and maintain a constant body temperature, for example birds and mammals.

6) Oviparous= producing young by means of eggs which are hatched after they have been laid by the parent, as in birds.

7)Vivaparous=bringing forth live young which have developed inside the body of the parent

Sorry if it's incorrect

Have a nice day
