Why is there no ocean-continent divergence? I need to know I'm just in 6th grade

1 answer:

3 0

Divergence is due to upwelling mantle thinning and extending the crust when the mantle decompressed and melts basalt is formed. Basalt and other mafic rocks from oceanic crust while continental crust is made up of mostly felsic (but some mafic) rocks. Upwelling mantle does thin continental crust and sometimes this thinning leads to new oceanic basins. Thus oceanic crust is formed from divergent oceanic plates (at mid oceanic rifts) and continental crust can become oceanic crust when upwelling mantle rifts continents into new oceanic basins

In the reaction glucose + fructose → sucrose + water, _____ is a reactant and _____ is a product. View Available Hint(s) Hint 1.

Answer:

The correct answers are: Glucose, Sucrose.

Explanation:

The given question is an example of a Chemical Reaction.
A Chemical Reaction can be defined as the process by which two or more substances interact with each other in such a way that a rearrangement of chemical bonds and molecular position occurs in them. This alteration in bonds and molecular position results in the formation of a new substance.
In a chemical reaction, the substances which are responsible for interacting with each other are called the Reactants.
In a chemical reaction, the new substances those are formed are called the Products.
A Chemical Reaction can be represented as follows:

W + X → Y + Z.

Here, W and X are reacting to form Y and Z.
So, W and X are the Reactants.
Y and Z are the Products.
As the Reactants react to form the Products, so the arrow → is represented from the Reactant to the Product.
In the given question,

glucose + fructose → sucrose + water

As arrow → always direct from Reactants to the Products, so the left side of the arrow will be the reactants and the right side of the arrow will be the products.
Hence, the Reactants are Glucose and Fructose.
The Products are Sucrose and Water.
So, Glucose and Fructose undergo chemical reaction to form Sucrose and Water.

Why do scientist need a common system of measurement

Natali5045456 [20]

Because science involves a lot of replication to confirm results. That means without the systems, it would take a long time to get the results right.

I GIVE A BRAINLYS Which process involves informal investigations done by native peoples as they use nature to meet their needs?

quester [9]

The process which involves informal investigations by native peoples to meet their needs is the native science discovery

Native science incorporates traditional knowledge and Indigenous perspectives, while today, non-Indigenous scientific approaches are commonly recognized as Western science. These two together is now embraced to meet people's needs

It has helped provide new ideas and dimensions on climate change, specific animal population declines, and sustainable harvesting practices.

<h3>What is science?</h3>

Science is defined as the intellectual and practical activity encompassing the systematic study of the structure and behaviour of the physical and natural world through observation and experiment processes
