What is Convection current?

Convection currents are defined as the result of differential heating where lighter, less dense, warmer materials rise while heavier, more dense, cooler materials sink. This is the movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the Earth's mantle.

Convection currents arise from differences in fluid density that arise due to a temperature gradient, resulting from the continuous replacement of the hot fluid in the region of the heat source with the nearby cold fluid which is known as the natural convection currents.

Thus, Radiogenic heat released- Cause: convection currents cycle through magma.

How much force would a shot putter need to make a 5.5 kg shot accelerate at 8 meters per so one squared

Answers

Answer:

44 N

Explanation:

Force applied can be calculated using the formula as follows;

F = m.a

Where;

F = force (Newton)

m = mass (kg)

a = acceleration (m/s²)

According to the information provided in this question, mass of shot put = 5.5kg, acceleration = 8m/s². Hence;

F = m × a

F = 5.5 × 8

F = 44 Newtons

The force needed by the shot putter is 44N.

Humans burn fossil fuels and wood, releasing carbon dioxide into the atmosphere. This carbon dioxide is then absorbed by trees for photosynthesis. These processes are contributory to which chemical cycle?

Answers

Carbon cycle. Because everything that is happening in the situation of this question is related to the carbon cycle. Fossil is being burnt which releasing carbon dioxide and the plant is taking it in to release oxygen!
It is a circle of life.

Carbon cycle controls the amount of carbon dioxide in the atmosphere. These processes are contributory to the carbon cycle in the       environment.

What is a carbon cycle ?

The carbon cycle is nature's method of recycling carbon atoms, which repeatedly go from the atmosphere into Earth's living things and back into it. The majority of carbon is preserved in rocks and sediments; the remainder is preserved in the ocean, the atmosphere, and living things.

Life on Earth is reliant on the carbon cycle. The quantity of carbon that is naturally released from reservoirs is equal to the amount that is naturally absorbed by reservoirs because nature tends to maintain carbon levels in balance. This carbon balance must be preserved for the earth to continue to support life.

Therefore, the carbon cycle is an important chemical cycle.

Explain how you are dependent upon at least one biotic and one abiotic factor.

Answer:

Biotic: We are dependent on plants, because we need them to eat.

Abiotic: We are dependent on water, because we need water to hydrate.

Hope this helps! <3

An example of a biotic and an abiotic factor that humans depend on are -

Biotic factor - plantsAbiotic factor - oxygen

The biotic factor is a factor that presents in an ecosystem that are living organisms and help in making and shaping ecosystems such as plants, animals, fishes, and others.

Human depends on the other organism mostly on plants for their food and energy as they can not produce their food.

The abiotic factor is the nonliving factor that interacts with the living organism or biotic factors to regulate and shape the ecosystems. It includes the carbon cycle, water, oxygen, temperature, and many others.

Humans depend on oxygen for their cellular respiration that provides energy for all essential cellular functions and without oxygen, there is no life present.

D. To gather green light in order to carry out photosynthesis

Answers

A because decomposers are associated

The role of fungus in the food web shown is to break down organic matter into carbon dioxide and water. The correct option is A.

What is fungus?

Fungus is a eukaryotic organism. They grew in soils and wood and moist and dark places. Fungi break down the material. While consuming the nutrients in the decaying matter, they produce enzymes that break down the material.

The biomass would be overrun with the dead matter without the majority of fungi, which is why they are helpful. Bacteria and actinomycetes are some additional decomposers. They act as nature's recycling machine by consuming animal carcasses, bones, dead plants, and various minerals thanks to their enzymes.

Therefore, the correct option is A. To break down organic matter into carbon dioxide and water.
