A rock with a porphyritic texture has large crystals “floating” in small crystals. Describe what made it form this way.
Answer: Summary. Intrusive igneous rocks cool from magma slowly because they are buried beneath the surface, so they have large crystals. Extrusive igneous rocks cool from lava rapidly because they form at the surface, so they have small crystals. Texture reflects how an igneous rock formed.

Why is the western part of lake balkhash composed of fresh water, while the eastern part is composed of salt water pls HELP!
Answer:
Because the density isn’t the same.
Explanation:
i took the test on edge 2020
The snowmelt provides the freshwater. Because the saltwater portion is deeper and the densities are different, freshwater and saltwater do not combine.
What was lake balkhash ?One of the largest lakes in Asia and the fifteenth largest lake in the world, Lake Balkhash is located in southeast Kazakhstan. It is situated in the endorheic (closed) Balkhash-Alakol Basin, which is in the eastern region of Central Asia.
Seven rivers drain the basin, the main one being the Ili, which supplies the majority of riparian inflow. Other rivers, including the Karatal, provide surface and subsurface flow. The Ili receives precipitation from the mountains of China's Xinjiang province, primarily in the form of vernal snowmelt.
Currently, the lake spans roughly 16,400 km2 (6,300 sq mi). Yet, similar to the Aral Sea, itis decreasing as a result of the removal and diversion of water from its feeders. There is a small, rather central channel in the lake. The western portion of the lake is freshwater. The eastern side of the lake is salty. On average, the east is 1.7 times deeper than the west.

Which is a way that paleontologists have contributed to humans' understanding of the history of life?
They found evidence that climate has not changed significantly.
They grouped organisms by the period in which they existed.
They discovered that the first humans lived with dinosaurs.
They learned that life has existed since Earth was created.
The correct answer is They grouped organisms by the period in which they existed.
Explanation:
The job of a paleontologist is to understand the history of life on our planet by analyzing evidence such as fossils. This work has allowed paleontologists to understand the evolution of life on Earth from simple organisms such as bacteria to complex organisms such as mammals.
Moreover, this has been possible because, through different analyses, paleontologists can group the organisms they find by the periods in which they existed and this makes possible understand better the history of life including the approximate time first organisms existed, how these changed over time and how these led to the organisms that exist today.
Answer:
They grouped organisms by the period in which they existed.

Ports in the Arctic Ocean can be used year-round to ship goods from Siberia to western Russia.
T or F.
Answer:
True.
Explanation:
The Northern Sea Route, Sevigny Morskoy put, shortened to Севморпуть, Sevmorput) is a shipping route officially defined by Russian legislation as lying east of Novaya Zemlya and specifically running along the Russian Arctic coast from the Kara Sea, along Siberia, to the Bering Strait. The entire route lies in Arctic waters and within Russia's exclusive economic zone (EEZ). Parts are free of ice for only two months per year. The overall route on Russia's side of the Arctic between North Cape and the Bering Strait has been called the Northeast Passage, analogous to the Northwest Passage on the Canada side.
While the Northeast Passage includes all the East Arctic seas and connects the Atlantic and Pacific oceans, the Northern Sea Route does not include the Barents Sea, and it therefore does not reach the Atlantic.
Melting Arctic ice caps are likely to increase traffic in and the commercial viability of the Northern Sea Route. One study, for instance, projects "remarkable shifts in trade flows between Asia and Europe, diversion of trade within Europe, heavy shipping traffic in the Arctic and a substantial drop in Suez traffic. Projected shifts in trade also imply substantial pressure on an already threatened Arctic ecosystem.

describe two models that show how earth and the sun move in space relative to each other.(I’ll mark brainliest and if you answer this it’ll give you 20 points)
Answer:
Model 1: Think of the ocean. The ocean is very large (like space) and contains a lot of smaller things in it (like solar systems and planets). Let's use a whale to model our solar system. The whale itself is the sun while the fish that follow it are like planets caught in its gravitational pull. The fish follow the whale, the whale moves around the ocean, like our solar system traveling around space while we orbit our sun.
Model 2: Let's just use a standard planet model for this (you know the one where the planets orbit the sun on it?). The room this model is in is like space, while the solar system occupies a corner of the room, kind of like our galaxy. The model itself represents our solar system and all the planets that orbit the sun.
Explanation:
I think the first model is better than the second, but I hope this helps
Read this Knowledge Article about the relationship betweem Canada and the Canadian province of Quebec. Consider the cultural differences that exist between Quebec and the rest of Canada, and write a short essay on the topic. Identify the key events that originally led to the unification of Canada and Quebec. Then discuss the cultural and social elements that have created a rift between Canada and the province.
Answer:
Canada has a unique relationship with the province of Quebec due to the joining of two drastically different cultures under one nation. This relationship has its roots in the seventeenth century, when the French colonized parts of Canada, including modern-day Quebec. In the eighteenth century, Great Britain defeated France in the Seven Years War, forcing the French to give up their colonies in the New World. Later, when English-speaking Canada became its own country, Quebec and its French-speaking citizens also became part of the new nation.
Language plays an important role in the Canada-Quebec relationship. Much of Canada is English speaking; however, Quebec is home to many French-speaking citizens. Because Quebec’s French-speaking population is a small minority in the general Canadian population, many Quebecers feel that the Canadian government overlooks them. They argue that their culture and needs are often considered less important than those of the English-speaking majority in Canada. This sentiment has sparked a heated debate in Canada about what rights should be granted to French-speaking Canadians and other minority groups. At times in the nation’s history, some Quebecers have wanted to split from Canada.
