Scientists can use the color of minerals to tell them apart.

Idiochromatic minerals <em>(self-colored) </em>due to their composition. The color is constant and predictable.

Allochromatic minerals <em>(other colored) </em>due to trace impurities or defects in their structure. The color is variable and unpredictable.

Pseudochromatic minerals <em>(false colored)</em> due to effects produced by light. The color is variable but a unique property of the mineral.

What caused the dramatic changes to the American family? What are those changes?
Klio2033 [76]

Answer:

Family life is changing. Two-parent households are on the decline in the United States as divorce, remarriage and cohabitation are on the rise. And families are smaller now, both due to the growth of single-parent households and the drop in fertility. Not only are Americans having fewer children, but the circumstances surrounding parenthood have changed. While in the early 1960s babies typically arrived within a marriage, today fully four-in-ten births occur to women who are single or living with a non-marital partner. At the same time that family structures have transformed, so has the role of mothers in the workplace – and in the home. As more moms have entered the labor force, more have become breadwinners – in many cases, primary breadwinners – in their families.

As a result of these changes, there is no longer one dominant family form in the U.S. Parents today are raising their children against a backdrop of increasingly diverse and, for many, constantly evolving family forms. By contrast, in 1960, the height of the post-World War II baby boom, there was one dominant family form. At that time 73% of all children were living in a family with two married parents in their first marriage. By 1980, 61% of children were living in this type of family, and today less than half (46%) are. The declining share of children living in what is often deemed a “traditional” family has been largely supplanted by the rising shares of children living with single or cohabiting parents.

What were some of the disadvantages the colonial militias had? Why was the battle of Saratoga a major turning point in the war?
choli [55]

Answer:

The battles and events that took place were often strategically planned with the hopes of gaining more control over a region, getting access to supplies and outmaneuvering the enemy all while trying to avoid as many casualties and military defeats as possible.

These strategies were also influenced by the geography of the region, which often affected the outcome of the battles.

Both sides had their own ideas on how to accomplish these goals and the strategies they used have been widely studied, scrutinized and even recreated.

In fact, numerous Revolutionary War strategy games are based on these very strategies and some types of battle reenactments, such as tactical battles or tactical events, use these strategies to try to defeat their opponents in recreations of the Revolutionary War battles.

The following is an overview of the strategies used in the Revolutionary War:

British Strategy:

British strategy changed throughout the course of the war as the British came up against more obstacles and challenges than they anticipated.

The British strategy at the beginning of the war was simply to contain the American Revolution in Massachusetts and prevent it from spreading.

This proved difficult though when the British suffered devastating casualties at the Battle of Bunker Hill in June of 1775 during the Siege of Boston.

After the Americans captured Fort Ticonderoga in New York, they brought the fort’s cannons to Cambridge, where they arrived on January 24, 1776, and planned to fortify the hills overlooking Boston harbor in an attempt to break the siege.

When powder for the cannons finally arrived on March 2, the Americans began firing on Boston. On March 4,  they mounted the largest cannons on Dorchester Heights. When the British saw the cannons on Dorchester Heights, they made an attempt to attack the heights but were thwarted by a storm. The British then decided to abandon Boston altogether and flee for Nova Scotia, Canada on March 17, 1776.

The new British strategy at this point was to capture New York City and use it as a base of operations. The British successfully captured New York on September 15, 1776 and launched the next phase of the plan in 1777.
