Each minute consists of 60 seconds. This is a widely accepted and standard measurement of time.

Sandstone is an example of sedimentary rock because it is formed from the accumulation and cementation of sand grains over time. Sedimentary rocks are formed through the processes of weathering, erosion, deposition, and lithification. Sandstone specifically originates from the compression and cementation of sand-sized grains, which can be composed of minerals such as quartz, feldspar, and clay. This process occurs in environments such as deserts, riverbeds, and beaches, where sand is deposited and compacted into solid rock.

Igneous rocks are formed when molten rock, also known as magma, cools and solidifies. This can happen either on the Earth's surface, where it is called lava, or below the surface, where it cools slowly over time. As the molten rock cools, minerals crystallize and interlock, forming a solid rock. This process of cooling and hardening can occur in different environments, such as volcanic eruptions or the solidification of magma chambers deep underground.

Glaciers are slow-moving masses of ice. They form when snow accumulates over time and compresses into ice. Due to their immense weight, glaciers flow downhill under the force of gravity. They are found in regions where snowfall exceeds melting, allowing the ice to accumulate and form large ice sheets or glaciers. Glaciers play a crucial role in shaping the landscape by eroding rocks and depositing sediment. They also serve as freshwater reservoirs and contribute to sea level rise when they melt.

Seismology is the study of earthquakes and the structure of the earth. It involves analyzing data from seismic waves, which are vibrations that travel through the earth's layers. By studying these waves, scientists can gain insights into the causes and effects of earthquakes, as well as the composition and behavior of the earth's interior. Seismic waves provide valuable information about the properties of rocks and the movement of tectonic plates, helping to understand and predict seismic activity.

The correct answer is molten rock-cools and hardens->igneous rock - weathered, eroded, & deposition->sedimentary rock- stress or heat-> metamorphic rock-heat & melted->molten rock. This sequence accurately depicts the process of the rock cycle. Molten rock, or magma, cools and hardens to form igneous rock. Over time, igneous rock can be weathered, eroded, and deposited to form sedimentary rock. Through the application of stress or heat, sedimentary rock can be transformed into metamorphic rock. Under extreme heat and pressure, metamorphic rock can melt and become molten rock again, completing the cycle.

The chief characteristics of the Lake-St. Lawrence lowlands include mostly mixed wood, wet climate soil, and rolling hills. This suggests that the region is predominantly covered by a diverse range of tree species and experiences a high amount of precipitation. The presence of rolling hills indicates a varied topography in the area.

The net migration rate is defined as the difference between the number of immigrants (people moving into an area) and emigrants (people moving out of an area) in a specific period of time, typically divided by the population of that area and multiplied by 1,000. This rate provides an indicator of the overall impact of migration on a population, whether it is experiencing a net gain or loss of people.

When ice sheets pick up rock, they become erratic forms. This is because as the ice sheets move and slide across the land, they can pick up and carry rocks of various sizes and types. These rocks are then transported by the ice sheets and deposited in different locations when the ice melts. These transported rocks, known as erratics, are often different from the surrounding rocks and can provide valuable information about past glaciation events and the movement of ice sheets.

To find the doubling time, divide 70 by the population growth rate. This is based on the rule of 70, which states that the doubling time of a population can be estimated by dividing 70 by the growth rate. By doing so, we can determine how long it would take for a population to double in size based on its growth rate.

Granite is an example of an igneous rock because it is formed from the solidification of molten magma or lava. It is a coarse-grained rock composed mainly of quartz, feldspar, and mica. Granite is commonly found in the Earth's continental crust and is widely used in construction and as a decorative stone due to its durability and attractive appearance.

The chief characteristics of the eastern cordillera include steep mountains, a rocky coast, and some dense forests. This suggests that the region is rugged and has a varied topography, with high elevations and cliffs along the coast. The presence of dense forests indicates a significant amount of vegetation in certain areas. These characteristics contribute to the overall scenic beauty and ecological diversity of the eastern cordillera.

The chief characteristics of the Appalachian mountains include rounded hills and mountains. This means that the peaks and slopes of the mountains in this region have a more smooth and gentle appearance compared to other mountain ranges. The rounded shape is a result of erosion and weathering over time, which has softened the ruggedness typically associated with steep mountains.

Each degree has 60 minutes.

The chief characteristics of the interior plains are flat and rolling land that is fairly dry. This means that the terrain is mostly level with gentle slopes, and there is not a significant amount of rainfall in the region. These characteristics contribute to the formation of a treeless zone and make it unsuitable for dense forests. Instead, the vegetation in the interior plains is likely to be adapted to the drier conditions.

The correct answer is net migration rate + natural increase rate. This is because the population growth rate is determined by the combination of natural increase (births minus deaths) and net migration (immigration minus emigration). By adding these two rates together, we can calculate the overall population growth rate.

The Canadian Shield is characterized by its saucer-shaped region. This refers to the large, flat area that covers a significant portion of Canada, stretching from the Great Lakes to the Arctic Ocean. The region is primarily composed of ancient rocks, including granite and gneiss, which have been shaped by millions of years of erosion. The Canadian Shield is also known for its numerous lakes, rivers, and wetlands, as well as its diverse wildlife. This unique geography and geology make the Canadian Shield an important ecological and economic resource for Canada.

Quartzite is an example of a metamorphic rock. Metamorphic rocks are formed when existing rocks undergo intense heat and pressure, causing them to change in composition and structure. Quartzite is formed from the metamorphism of sandstone, where the grains of sandstone are recrystallized and fused together by heat and pressure. This process transforms the original sedimentary rock into a hard, durable, and often shiny rock with a high quartz content.

The chief characteristics of the Arctic lowlands are that they are flat, low-lying areas that are covered with soil. These lowlands do not have any significant elevation changes and are generally smooth and level. The presence of soil indicates that there is some vegetation and plant life in this region, although it may be sparse due to the harsh Arctic climate. Overall, the Arctic lowlands are characterized by their flatness and the presence of soil, which distinguishes them from other types of Arctic landscapes such as tundra or mountains.

Australia is the only continent and country entirely located in the Southern Hemisphere. It lies south of the equator, surrounded by the Indian and Pacific Oceans. Its unique geographic position isolates its ecosystems and influences its climate patterns. The other options are incorrect as they have landmasses in both hemispheres.
