New crust forms where two plates pull apart from each other and the correct option is option C.
New crust forms at divergent boundaries, which are locations where two tectonic plates are moving away from each other. As the plates separate, magma from the underlying mantle rises to fill the gap created by the spreading plates.
This magma solidifies and forms new crust, adding to the existing plates. Divergent boundaries are typically found along mid-ocean ridges or continental rift zones.
Convergent boundaries (option A) are locations where two plates collide, often resulting in the subduction of one plate beneath the other. Ocean trenches (option B) are formed at subduction zones, where one tectonic plate is forced beneath another.
The lithosphere (option D) is the rigid outer layer of the Earth, including the crust and uppermost part of the mantle, but it is not the specific location where new crust forms.
Thus, the ideal selection is option C.

Consider the chromosome.
The parts of a chromosome are labeled. The lines on the chromosome are labeled b.
Which best describes the function of the part labeled b?
carries all the genetic information of the organism
provides the master instructions for the cell
joins sister chromatids
codes for a specific trait
Answer:
D.
Explanation:
..
The part labelled B is gene which codes for a specific trait. So, the correct option is (D).
What are Genes?Genes are defined as the basic unit of heredity passed from parent to child that are composed of sequences of DNA and arranged one after the other at specific locations on chromosomes in the nucleus of cells.
The main function of genes is to code for a specific trait where every individual on this earth is different from each other. The traits that make individuals alike are the genes they carry.
Traits like eye color, height, ear size, height are controlled by genes where as such characters like fur color, flower size, flower color are also controlled by genes. The characteristics responsible for what a person is like are borne by genes.
Thus, the part labelled B is gene which codes for a specific trait. So, the correct option is (D).

Why is sustainable development concerned with the needs of future generations?
Sustainable development is concerned with the needs of future generations because Earth's natural resources are
_________.
Answer:
Sustainable development is defined as the principle to meet present need without affecting future generation needs.
Sustainable development is much concerned with the future needs because humans are utilizings the natural resources of the Earth in order to fulfil present needs. But the natural resources of the Earth are non-renewable and will take hundreds or thousands of year to form again, so it is possible that our future generation will unable to consume those natural resources.
Even natural resources cannot be replaced by other resources, example: carbon-based fossil fuel.
Hence, people consuming natural resources in large quantity which can affect future generation needs, as natural resources are non-renewable sources of energy.

What do you mean by food web?A food web is a natural connection of food chains and a graphic representation of what-eats-what in an ecological community. Another name for the food web is the consumer resource system.
A food web consists of several food chains. A food chain only follows one path when animals find food. eg: A hawk eats a snake that ate a frog that ate a grasshopper.
A food web consists of the connections of different food chains. In nature, many food chains are interconnected thanks to many producers and consumers. Such a complex network of food chains is called a food web.

A student drew this model to show the flow of convection currents
on Earth.
Part A
Is the model accurate? Explain your answer.
Answer:
Yes the model is correct
Explanation:
Transfer of heat energy takes place usually any of these three processes namely; Conduction, Convection and Radiation. In conduction, transfer of heat energy takes place by microscopic collisions of particles within a body. In radiation, heat, light and energy through any source is sent out from something and moves through space without a material medium of propagation. In Convection, heat transfer happens because of the movement of the bulk of molecules within fluids.
We can define convection currents as a natural process of heat transfer involving the movement of energy and heat from one place to another.
The equator is the part on Earth that is nearest to the sun hence it receives much heat. As a result of this, the air near the equator rises upwards as it becomes less dense and later spreads out and again descends towards the equator. This process is responsible for the continual circulation of air which is called wind. It is due to the process of atmospheric convection currents that the clouds are kept aloft.
From the foregoing, the model shown in the image has been validated as a correct model of convection current in nature.
Answer:The model accurately shows convection. However, these large convection currents would occur only if Earth did not rotate. Because Earth rotates, smaller convection cells form.

Which of the following choices contains two ways in which carbon dioxide
enters the atmosphere?"
O A erosion and transpiration
O B decomposition and respiration
C volcanic activity and photosynthesis
Dhuman activity and formation of fossil fuels
Decomposition and respiration choices contains two ways in which carbon dioxide enters the atmosphere.
What is Decomposition?
Decomposition, often known as rot, is the breakdown of dead organic matter into more basic organic or inorganic components such carbon dioxide, water, simple sugars, and mineral salts.
The procedure, which is a component of the nutrient cycle, is crucial for recycling the limited amount of matter that takes up real estate in the biosphere.
Creatures like worms also contribute to the breakdown of the organic compounds. Decomposers or detritivores are organisms that carry out this process.
Therefore, Decomposition and respiration choices contains two ways in which carbon dioxide enters the atmosphere.

What is hydropower?Hydropower is a renewable energy source and has many benefits, including the ability to generate large amounts of electricity without emitting greenhouse gases. However, it also has limitations. Hydropower is dependent on the availability of water resources, which can vary depending on seasonal changes, weather patterns, and other factors. In addition, hydropower can have negative environmental impacts, such as disrupting natural river ecosystems and affecting fish populations.

The dodo bird used to be found in high populations on their island habitat. However, sailors would stop by the island to eat the dodo birds because they were easy to catch. Eventually, the dodo population went extinct.
This is an example of biodiversity loss due to:
Overpopulation
Invasive Species
Habitat Destruction
Overexploitation
Answer:
Overexploitation
Explanation:
Gradual declination of certain species of organisms in an ecosystem, which leads to their extinction occurs from time to time. This is referred to as the loss of biodiversity or simply biodiversity loss. Many factors contribute to the loss of biodiversity in an ecosystem, they include: habitat loss, invasive species, overexploitation etc.
Based on the description of the cause in this question, the biodiversity loss is as a result of OVEREXPLOITATION. Overexploitation is when certain animals are utilized more than the surviving ones can reproduce to cover the loss.
In this case, the sailors overexploited the dodo birds in their island habitat by feeding on them excessively because they were a easy catch.
