What function provides insolation?
The function that provides insolation is solar radiation, specifically solar energy received by the Earth's surface. Insolation is the amount of solar radiation reaching a specific area over a given time period. It is an essential factor in understanding climate and ecosystems.
What is a bond that is formed by sharing electrons?
A covalent bond is formed by sharing electrons between atoms. This type of bond occurs between nonmetal atoms.
What rock is soft enough to be scratched by a nail?
Rocks that mostly contain minerals like mica, gypsum, and talc can be scratched by a fingernail.
Which term describes the portion of a peach that can be eaten by humans?
The edible part of a peach that can be eaten by humans is called the flesh or fruit. It is the soft, sweet part of the peach surrounding the hard pit or stone.
Is a walnut tree vascular or an non-vascular?
A walnut tree is vascular, meaning it has specialized tissues for transporting water and nutrients throughout the plant. The vascular system in plants consists of xylem for transporting water and minerals from the roots, and phloem for transporting sugars produced during photosynthesis.

How far apart would two successive index contours be on a map with a contour interval of 5 meters?
Two successive index contours would be 10 meters apart on a map with a contour interval of 5 meters. This means that each index contour line represents a change in elevation of 10 meters from the next adjacent line.
What is the name for solid surface of the earth?
The solid surface of the Earth is called the lithosphere. It includes the crust and the upper mantle and is divided into several tectonic plates that float on the semi-fluid asthenosphere below.
When millions of years ago most of the land on earth was covered by water?
During the Precambrian era, which began around 4.6 billion years ago, most of Earth's surface was indeed covered by water. This period lasted for about 4 billion years until the emergence of landmasses and the subsequent diversification of life forms.
Why are trees and building useful reference points?
Trees and buildings are useful reference points (for navigating the urban landscape, I'm assuming) because the do not move appreciably in human timescales. Were you as swift as a tectonic plate or as small as a bacterium, the utility of these landmarks may diminish.
How close to a perfect sphere is Earth's true shape?
Earth's shape is an oblate spheroid, meaning it is nearly spherical but slightly flattened at the poles and bulging at the equator. The difference between the polar and equatorial diameters is about 42.75 kilometers, making Earth's shape very close to a perfect sphere.
What is the effect of time on a system model?
The effect on time on a system model makes it towards scientist can measure things in real time & make models to describe what happened in the past & what might happen in the future.
What global process puts stress on rocks and faults?
The process of plate tectonics puts stress on rocks and faults. This occurs as the Earth's lithosphere is divided into plates that move and interact with each other, leading to the accumulation of stress along faults where rocks are being pushed or pulled in different directions. This stress can eventually cause rocks to break and fault lines to rupture, resulting in earthquakes.
Which part of da earth surface does not experience seasion?
The equator is a region on Earth's surface that does not experience distinct seasons. This is because the equator receives relatively consistent sunlight throughout the year due to its position along the Earth's axis.
What are the types of wind deposit?
The types of wind deposits include dunes, loess deposits, and sand sheets. Dunes are mounds of sand shaped by wind, while loess deposits consist of fine-grained sediment deposited by wind. Sand sheets are large areas covered with wind-blown sand.
Does a wind - move air from a warm place to a cool place?
Air flows from areas of higher pressure to areas of lower pressure.
Related Information:
Temperature is irrelevant except that temperature plays its part in creating areas of higher or lower localized atmospheric pressure.
What percent of earth's serface water is in the form of glacial ice?
Approximately 69% of Earth's surface freshwater is stored in glaciers and ice caps. This frozen water represents a significant portion of the planet's accessible freshwater resources.
What provides the framework for all silicate minerals?
Silicate minerals are based on a fundamental building block called the silicon-oxygen tetrahedron, which consists of a silicon atom bonded to four oxygen atoms in a pyramid-like structure. These tetrahedra link together in various arrangements to form the framework structure that is characteristic of silicate minerals.
Why does the center of the continent have hotter summers and colder winters than the coasts?
the difference that have is that one side is more hot and the other coold , because the wind is strong and that what cause the climograph. thanks ..
What is the definition of random change?
Random change refers to a process where outcomes occur without any pattern or predictability. It is characterized by uncertainty and lack of control over the direction or magnitude of the change. Random change can occur in various aspects of life, such as genetics, behavior, or environmental factors.
Which of the mineral groups is most abundant in the crust?
Quartz is the most abundant single mineral. Feldspars are, as a group, the most abundant minerals. Quartz and feldspars are classified as silicate minerals, the classification of mineral with the most abundance in the Earth's crust.
What does it mean when the water table is near the earths surface?
The water table is the level at which the submarine pressure is far from atmospheric pressure. It may be conveniently visualized as the 'surface' of the subsurface materials that are saturated with groundwater in a given vicinity. However, saturated conditions may extend above the water table as surface tension holds water in some pores below atmospheric pressure.[1] Individual points on the water table are typically measured as the elevation that the water rises to in a well screened in the shallow groundwater.
The groundwater may be from infiltrating precipitation or from groundwater flowing into the aquifer. In areas with sufficient precipitation, water infiltrates through pore spaces in the soil, passing through the unsaturated zone. At increasing depths water fills in more of the pore spaces in the soils, until the zone of saturation is reached. In permeable or porous materials, such as sands and well fractured bedrock, the water table forms a relatively horizontal plane. Below the water table, in the phreatic zone, permeable units that yield groundwater are called aquifers. The ability of the aquifer to store groundwater is dependent on the primary and secondary porosity and permeability of the rock or soil. In soil that are less permeable, such as tight bedrock formations and historic lakebed deposits, the water table may be more difficult to define.
The water table should not be confused with the water level in a deeper well. If a deeper aquifer has a lower permeable unit that confines the upward flow, then the water level in a well screened in this aquifer may rise to a level that is greater or less than the elevation of the actual water table. The elevation of the water in this deeper well is dependent upon the pressure in the deeper aquifer and is referred to as the potentiometric surface, not the water table.
How are friction and heat related?
try rubbing your hands together quickly. the heat you feel is an effect of friction. friction occurs when two surfaces rub together.as a result of friction, heat is produced. for example, when a person skates on ice, the ice and skate rub together. this friction gives heat. :)
How do you experance day and night?
Day and night are caused by the Earth rotating on its axis. As the Earth rotates, different parts of the planet are either facing towards the sun (daytime) or away from the sun (nighttime). The cycle of day and night occurs approximately every 24 hours.
