What is Great lakes?The Great Lakes are a collection of five sizable lakes in North America that are either on or close to the Canadian-American border. They make up the world's largest collection of freshwater lakes. Due to their hydrological connection, Lakes Michigan and Huron are occasionally referred to as Lake Michigan-Huron. When taken as a whole, Michigan-Huron would have a surface area greater than Lake Superior but a smaller amount of water overall.Between Lake Huron and Lake Erie, there is a sixth, much smaller lake called Lake St. Clair that is a component of the Great Lakes system but is not regarded as one of the "Great Lakes."Learn more about the great lake here:

How do the different methods used to calculate population density reveal different information about the pressure the population exerts on the land? Give examples
Answer: Population density shows location of people, growth, and the flow of people.
Explanation: Arithmetic is the number of people divided by the total land area. Arithmetic density compares the population of one area to another. In a city there is more likely to have a greater arithmetic density than the suburbs.
Physiological density is the population divided by arable land. Physiological density shows how much population a certain area can sustain.
Agricultural density is the amount of farmers divided by arable land. This shows how much arable land can support active farmers

Minerals that grow as crystals in cooling lava can become magnetized if they contain _______.
Minerals that grow as crystals in cooling lava can become magnetized if they contain iron.
Igneous rocks are composed of minerals that crystallise at a variety of different temperatures. This explains how a cooling magma could contain some crystals while still being primarily liquid. The Bowen reaction series is the pattern of mineral crystallisation from a magma.
Individual plagioclase crystals can be zoned from more sodium-rich around the exterior to calcium-rich in the centre when cooling occurs reasonably quickly. Because it controls how long the reaction can last before all the silica is consumed, the initial magma's composition is crucial to the crystallisation of magma.

The entire west coast of the united states experiences earthquakes. in central and southern california this is due to?
The entire west coast of the United States experiences earthquakes. In Central and Southern California this is due to it being located on an active plate boundary.
What are active plate boundaries?Active plate boundaries modify the surface of the Earth and the internal structure of deformation in the lithosphere. During convergence in the oceanic and continental plate, the oceanic plate which is denser sinks beneath the continental plate which is buoyant. This process is known as subduction and it is the process responsible for the abundance in volcanic activities and the strongest earthquakes on the Earth ever recorded. The Pacific plate's Ring of Fire is the most active volcano situated on an active plate boundary.

The presence of glossopteris leaves and mesosaurus on disconnected continents are strong _______ evidence for continental dri
The presence of glossopteris leaves and mesosaurus on disconnected continents are strong fossil evidence for continental drift.
There are numerous examples of fossils found only on different continents, indicating that the continents were once connected. Only in southern Africa and eastern South America can bones of Mesosaurus, a crocodile-like reptile that lived 286 to 258 million years ago, be found. Traveling by swimming between continents would have been physically impossible for Mesosaurus.
This shows that during the Early Permian, South America and Africa were connected. The Early Permian (299 million years ago) saw the evolution of Glossopteris, a woody, seed-bearing shrub or tree that went on to dominate the era and persisted until the end of the Permian. Australia, South Africa, South America, India, and Antarctica all contain its fossil remains.

In a typical weathering sequence, rocks break down into secondary minerals which further undergo physical and chemical weathering to form primary minerals. true false
False, In a typical weathering sequence, rocks break down into secondary minerals which further undergo physical and chemical weathering to form primary minerals.
Weathering is the degradation of rocks, soil, and minerals as well as wood and man-made materials due to exposure to water, atmospheric gases, and biological organisms. Weathering occurs in situ (in situ, with little or no movement) and is therefore distinct from erosion, which involves the transport of rocks and minerals by agents such as water, ice, snow, wind, waves, and gravity force.
Weathering processes are divided into physical and chemical weathering. Physical weathering refers to the breakdown of rocks and soils by the mechanical action of heat, water, ice, or other agents. Chemical weathering involves the chemical reaction of water, atmospheric gases, and biological chemicals produced with rocks and soil. Water is a major contributor to physical and chemical weathering, although atmospheric oxygen and carbon dioxide and the activities of biological organisms are also important. Chemical weathering by biological action is also known as biological weathering.

What observations can be made about a rock at the hand-specimen scale, if the components of a rock are visible in a hand specimen?
When igneous rocks cool and solidify below the surface, they are referred to as intrusive rocks. Because they are invasive in nature, plutons are frequently referred to as such. An igneous intrusive rock mass that has cooled in the crust is referred to as a pluton.
Magma cools slowly as it travels through the Earth. Intrusive igneous rocks feature crystals that are visible because slow cooling gave time for massive crystals to develop. Granite is the most widely accepted kind of intrusive igneous rock. Four directly visible minerals—feldspar (white), quartz (translucent), hornblende (black), and biotite—combine to form granite (black, platy).
Phaneritic textures are typical of intrusive igneous rocks, which progressively crystallized below the surface of the Earth. The minerals have the time to develop and form sizable crystals while the lava cools gradually. A phaneritic igneous rock has minerals that are big enough to allow the eye to view each crystal. The igneous rocks gabbro, diorite, and granite are instances of phaneritic rocks.

An animal must be buried for tens of thousands or millions of years before it (and the layer around it) solidify into rock in order to become a fossil. Several fossils are still buried. Only when they are revealed by excavation or erosion can we locate them.
An animal must be immediately and thoroughly buried in ash or sediment before it has a chance to decay in order to become a fossil. The earliest animals were minuscule and did not leave any fossils.

Climate is only one factor in farming; more needs to be learned about the local soil properties.

The correct answer is Option A) moon.
If the chunk of gold weighed 1N on the moon, it would have the largest mass of the gold.
Why will it be possible?Weight is a physical quantity which tells us how strong the gravitational force is acting on an object.
The formula for weight is W = mg
Here, m is the mass of the object,
g is the acceleration due to gravity.
Now we have the following information,
W = 1 N
Also, m = [tex]\frac{W}{g}[/tex]
This means, m ∝ [tex]\frac{1}{g}[/tex]
As acceleration due to gravity on the moon is 1.62 m/[tex]s^{2}[/tex]
