Grade 9 Geography Review

Canada is the second largest country in size because it has a vast land area, spanning over 9.9 million square kilometers. It is only surpassed in size by Russia, making Canada the second largest country in the world. Its large size is attributed to its diverse geography, including expansive forests, lakes, and mountain ranges.

The strong force is the fundamental force that binds together protons and neutrons in the nucleus of an atom. This force is responsible for holding the nucleus together despite the repulsive electromagnetic forces between the positively charged protons. Without the strong force, the nucleus would not be stable and atoms would not exist as we know them.

Each bearing on a compass is separated by 22.5 degrees. This means that when moving from one bearing to the next, there is a 22.5-degree angle between them. This angle is consistent throughout the entire compass, allowing for accurate navigation and direction finding.

Gross Domestic Product (GDP) is the total value of all goods and services produced within a country's borders in a specific time period. It includes not only wages, but also profits, investments, government spending, and net exports. GDP is used as a measure of a country's economic performance and is often used to compare the economic growth between different countries.

The International Date Line is not a line of latitude. It is an imaginary line that runs from the North Pole to the South Pole and serves as the boundary between two consecutive calendar days. It is located at approximately 180 degrees longitude and is used to determine when a new day begins. Unlike lines of latitude, which are parallel to the equator, the International Date Line is a meridian line that follows the 180-degree longitude line.

A map scale is used for multiple purposes. Firstly, it is used to measure distances on a map, allowing users to determine the actual distance between two points on the map. Secondly, it is used to convert map distances to real distances, enabling users to understand the real-world distances represented on the map. Therefore, the correct answer is "all of the above" as a map scale serves both of these functions.

Ontario is located in the south eastern climate region of Canada. This region experiences a humid continental climate, characterized by hot summers and cold winters. The proximity to the Great Lakes influences the climate, with the lakes moderating temperatures and causing increased precipitation. The south eastern region of Ontario, including cities like Toronto and Ottawa, has a milder climate compared to other parts of the province.

Nunavut is located in the Arctic climate region. This region is characterized by extremely cold temperatures, long winters, and short, cool summers. The Arctic climate is known for its ice and snow-covered landscapes, as well as the presence of permafrost. The region experiences very little precipitation, and the vegetation is limited to hardy plants and mosses. The Arctic climate is unique and only found in the northernmost parts of the world, including Nunavut.

The equator is located at 0 degrees latitude, both north and south of the Earth's equator. This imaginary line divides the Earth into the Northern Hemisphere and the Southern Hemisphere.

Canada's natural resource base is not based on animals in the area. This means that Canada's natural resources, such as minerals, forests, and energy sources, do not rely on the presence or availability of specific animal species in the region. Instead, Canada's natural resource base is primarily influenced by factors such as climate, erosion, and landforms.

The other three options mentioned (divided line scale, direct statement scale, and representative fraction) are all types of map scales that are commonly used. However, "metric division scale" is not a recognized type of map scale.

Most of Canada is in the taiga climate region. The taiga is characterized by long, cold winters and short, cool summers. This climate region is found in the northern parts of North America, Europe, and Asia, and it is dominated by coniferous forests. The taiga climate is influenced by its high latitude and proximity to cold air masses from the Arctic. It is well-suited for the growth of evergreen trees like spruce, fir, and pine, which can withstand the harsh winter conditions. This climate region covers a significant portion of Canada, particularly in the northern parts of the country.
