How do glaciers cause erosion and deposition

Answers

when glaciers (slowly) glide down a mountain they carry down earth and rock and brings it down. After the glacier has completely melted the earth from the mountain id deposited to the lower ground.

Like flowing water, flowing ice erodes the land and deposits the material elsewhere. Glaciers cause erosion in two main ways: plucking and abrasion.
Plucking is the process by which rocks and other sediments are picked up by a glacier. They freeze to the bottom of the glacier and are carried away by the flowing ice.

1. Generally speaking, where on the periodic table are the elements that form ions requiring!Roman numeral in their names?

Answers

Answer:

The middle, or the transitional metals

Explanation:

When naming elements, we use roman numerals to indicate what their charge is. The charge of an element is affected by their number of valence electrons (outermost electrons).

Transitional metals are generally multivalent, meaning that element has more than one possible number of valence electrons. This makes them have more than one possible charge. Roman numerals indicate which charge of that element is used/discussed.

238,2U --> 234Th +
90

Answers

Answer:

$\n_(2)^(4) \alpha$

Explanation:

In this question, we wish to find the missing nuclei for the equation:

$\n_(92)^(238) U\rightarrow _(90)^(234) Th + _(Z)^(A) X$

In order to find the missing species, we need to use the charge and mass balance law. That is, the mass should be conserved: the total mass on the left-hand side with respect to the arrow should be equal to the total mass on the right-hand side with respect to the arrow:

$238 = 234 + A$

Notice from here that:

$A = 238 - 234 = 4$

So far we know that the mass of X is 4. Similarly, we apply the law of charge conservation. The total charge should be conserved:

$92=90+Z$

From here:

$Z = 92-90=2$

We have a particle:

$\n_(2)^(4) X$

Looking at the periodic table, an atom with Z = 2 corresponds to helium. This can also be written as an alpha particle:

$\n_(2)^(4) \alpha$

Which of the following is a hypothesis that you could form about how soilacidity affects the growth of blueberries?

Answers

Answer:

Explanation:

Most hypothesis involves the statement of a problem. It is one of the easiest way to explain results from experiments and a pool of observation.

To create a hypothesis about how soil acidity affects the growth of blueberries, we must bear in mind the follow:

The dependent variable is the growth of the blueberries.

The independent variables are the chemicals we might be adding to the soil to increase the acidity.

Our best hypothesis would be "how the addition of different pH of acid to soil affects the growth of blueberries".

Why can water dissolve many ionic compounds

Answers

To dissolve an ionic compound, the water molecules must be able to stabilize the ions that result from breaking the ionic bond. Water is a polar molecule. It has a permanent dipole. ... The negative ions have several water molecules around them, all with their H atoms close to the negative ion
