A copper penny will scratch gypsum because material with a higher hardness can scratch anything.
Define gypsum.Calcium Sulfate dihydrate, having the chemical formula CaSO42H2O, makes up the soft sulfate mineral known as gypsum. [4] It is commonly mined, used as fertilizer, and the primary ingredient in various types of drywall, blackboard chalk, and plaster. Many societies, including Ancient Egypt, Mesopotamia, Rome, the Byzantine Empire, and the Nottingham alabasters of Medieval England, utilized a large fine-grained, white or lightly colored form of gypsum for sculpture. Selenite crystals that are translucent form when gypsum additionally crystallizes. It develops as an evaporite mineral and a byproduct of the hydration of anhydrite.

Bedrock, lava, sand dunes, sediment deposited by glaciers, or sediment deposited by rivers, lakes, or the ocean these are referred to be parent material.
What is parent material in soil formation?For the majority of soil growth, parent material serves as the foundation. Organic materials or mineral rock could be the parent substance. Soil formation starts when parent rock material is exposed to the atmosphere or when organic material, minerals, or both are deposited on the earth's surface.What are the primary elements that lead to soil formation from the original substance?The five components are:
1) the original material;
2) relief or terrain;
3) creatures, including people;
4) climate; and
5) time.
A single parent material will develop into a different soil individual if it is exposed to several climes.
What responsibilities does parent material have?The unconsolidated mineral and organic deposits where soil is growing are referred to as parent material.

Magma may cool and crystallize to become solid igneous rock because magma is more slowly in a deep pluton than in a shallow sill.
Define igneous rock.When hot, molten rock Crystallizes and solidifies, igneous rocks—named after the Latin word for fire are created. The melt begins deep within the Earth near hot regions or active plate borders, then it rises toward the surface.
According to where the molten rock hardens, igneous rocks are categorized into two groups: intrusive and extrusive.
What is Intrusive Igneous Rocks?When magma is imprisoned deep inside the Earth, intrusive, or plutonic, igneous rocks are created. Massive globules of molten rock are rising to the surface.
What is Extrusive Igneous Rocks?When magma escapes and cools above (or very close to) the Earth's surface, igneous rock known as extrusive rock is created. These are the kinds of rocks that are created by erupting volcanoes and gushing fissures. When exposed to the relatively cool temperature of the atmosphere, the magma, which is known as lava when molten rock erupts on the surface, cools and solidifies practically instantaneously.

The points where space (aerial extent) and location converge worry geographers.
Human geographers investigate the spatial dimensions of human behaviour, including where, why, and the outcomes of what people do. Physical geographers describe, simulate, and forecast the patterns of natural phenomena like climate, landforms, soil development, and river movement.

Cultural convergence occurs more rapidly with improved transportation.
What is cultural convergence?Cultural convergence is the phrase used to describe how civilizations tend to alter and adapt when they are frequently exposed to different cultures. Cultures will become more similar the more they interact with one another. Time and points of interaction are two major aspects that affect cultural convergence. Greater commonalities between cultures emerge from longer exposure times, of course. Increased contact rates, accessibility to communication and transportation, and membership in the same groups all speed up the rate of convergence.

how seafloor spreading leads to the development of new land?
Seafloor spreading is a geologic process in which tectonic plates—large slabs of Earth's lithosphere—split apart from each other. Seafloor spreading and other tectonic activity processes are the result of mantle convection. Mantle convection is the slow, churning motion of Earth’s mantle. Convection currents carry heat from the lower mantle and core to the lithosphere. Convection currents also “recycle” lithospheric materials back to the mantle. Seafloor spreading occurs at divergent plate boundaries. Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense. The less-dense material rises, often forming a mountain or elevated area of the seafloor.
identify and explain how each sphere is involved
All of the spheres communicate with one another. For instance, rain (hydrosphere) falls from clouds in the atmosphere to the lithosphere and creates streams and rivers that serve as both sources of water for plant development and drinking water for both humans and animals (biosphere).River activity erodes the lithosphere on riverbanks and uproots plants (biosphere). Rain-fed rivers wash filth away.
The four subsystems of the Earth's system—land, water, life, and air are used to categorize everything. "Spheres" is the term for the subsystems. The geosphere (land), hydrosphere (water), biosphere (life) and atmosphere are the specific names for them (air). This approach is employed by environmentalists to categorize and investigate the organic and inorganic substances that can be found on Earth.
What are the types of Earth's spheres?geosphere, hydrosphere, atmosphere, cryosphere, biosphere.
GEOSPHERE
The Earth's rocks and minerals make up the geosphere, from the molten rock and heavy metals in the planet's center to the sand on beaches and mountain tops.
HYDROSPHERE
Water on a planet in its entirety is referred to as the hydrosphere. The hydrosphere is made up of water that is present on the planet's surface, underground, and in the atmosphere. Liquid, vapor, or ice can all exist in a planet's hydrosphere. Oceans, lakes, and rivers are examples of the liquid water that is present on Earth's surface.
ATMOSPHERE
The layer of gases that covers Earth's surface is called an atmosphere, and it is what humans breathe. Because of Earth's gravitational pull, it is kept close to the planet's surface. For measuring air pressure, use a barometer. from the three elements that make up the atmosphere: nitrogen, oxygen, and argon.
CRYOSPHERE
This includes oceanic regions that are frozen, such the waters around Antarctica and the Arctic. Water freezes solid in several locations on Earth because of the extreme cold. These snowy or icy patches, which are exposed to temperatures below zero degrees Celsius.
BIOSPHERE
The areas of Earth where life is present are referred to as the biosphere. The biosphere includes the deepest tree roots, the shadowy depths of the ocean, lush jungles, and tall mountain peaks. Earth is described by scientists as a sphere. The lithosphere is the Earth's solid surface layer
How all spheres are interact with each other?Precipitation, like rain or snow, can fall to the surface of the Earth when an area of air in the atmosphere becomes saturated with water. By encouraging erosion and weathering, two surface processes that gradually reduce huge rocks into smaller ones, that precipitation links the hydrosphere with the geosphere
