Why have we not found examples in the fossil record of every animal that ever lived on earth?
We have not found examples in the fossil record of every animal that ever lived on earth because
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. The oldest animal fossils are found in strata from shallow equatorial seas that were formed more than 600 million years ago.

Impact of depletion of land
Impact of depletion of land Beyond the loss of agricultural land, soil erosion has other negative repercussions. In streams and rivers, it has increased pollution and sedimentation, blocking these waterways and resulting in a loss in fish and other species. Additionally, deteriorated soils are frequently less able to retain water, which can make floods worse.
The portion of Earth's solid surface that is not always covered by water is known as the "land" or "ground."
Land degradation is a process in which a number of human-caused processes working on the land reduce the value of the biophysical environment. It is understood to be any alteration or disturbance to the land that is either harmful or unwanted. Natural disasters are not considered a cause, but human actions can have an indirect impact on events like floods and bushfires. Resource depletion is the state in which natural resources are being used up more quickly than they can be regenerated. Developing nations misuse their lands for economic gain in an effort to attain economic progress.

Why does summer in the northern hemisphere occur when earth is farthest from the sun?.
Seasons are not caused by the Earth's shifting distance from the sun. We are usually the farthest away from the sun in early July during northern summer and the closest in January during northern winter.
Earth's tilt on its axis is what causes the seasons. Due to the tilt of the Earth's northern hemisphere toward the sun, it is currently summer there. We are mostly exposed to the sun's beams.
Likewise, winter has arrived in the Southern Hemisphere due to the tilt of the Earth's axis away from the sun. Cooler temperatures result from more indirect sunlight.
However, the Earth's shifting distance from the sun has an effect on the length of the seasons. That's because when we're the furthest away from the sun, like right now, Earth's orbit is the slowest. As a result, summer is the longest season in the Northern Hemisphere while winter is the longest season in the Southern Hemisphere.
In the Northern Hemisphere, winter is the shortest season, while summer is the shortest in the Southern Hemisphere, both by approximately five days.

Which atmospheric layer is typified by a relatively small change in temperature?
Stratosphere atmospheric layer is typified by a relatively small change in temperature.
Let's find out. Air is considered unstable in the lowest atmospheric layer of the air mass if it is warmer and/or more humid than the surrounding air. In this case, the air rises because this air mass is warmer than the surrounding air. In unstable environments, the weather can change suddenly and become violent.
Clouds are expected to develop an atmospheric layer vertically if unstable air masses must move up the mountainside. The lenticular clouds standing over the mountains indicate turbulence. Cumulonimbus clouds are associated with maximum turbulence.

Where did the oxygen in our atmosphere come from?
Describe and explain the three reasons glaciers flow. please use complete sentences and proper grammar.
The bedrock has a slope, which causes the glacier to move downward as the first cause of glacial movement. Second, since ice crystals must bend to flow downward, the glacier's ice sheets help it do so. Ice sheets are created when ice crystals deform. Thirdly, the flow of melted water beneath the glacier is what causes it to move.
Why does Glacier flow occur?The weight and creep characteristics of ice have a straightforward effect on glacier flow. When ice is subjected to shear stress over time, it will creep, or plastically deform. Under constant shear stress, the rate of plastic deformation starts out quickly before tapering off to a constant amount.
A curved graph will be produced if this stable value, the shear-strain rate, is plotted against the stress for a wide range of applied stress values. The chart demonstrates the shear strain rate's near proportionality to the shear stress cube, which is the flow law or fundamental law of ice.
All assessments of the movement of ice sheets and glaciers are built around this fundamental law, which glaciologists frequently refer to as the Glen flow law.

The aerial distance between the two points is 100 km on a topographic map.
The relationship between map distance and real ground distance is known as map scale.
What is map scale?The ratio between a distance on a map and its actual distance on the ground is known as the map's scale. This simple concept is complicated by the fact that scale must vary across a map due to the curvature of the Earth's surface. This change makes the idea of scale significant in two different ways.The ratio of a distance on Earth to the same distance on a map is known as the map scale or cartographic scale. There are three primary scale types found on maps: fractional scales, graphic scales, and written or verbal scales. One kilometer on the ground is equal to one centimeter on a map with a scale of 1:100,000.People can accurately visualize how the distances mentioned on the map are plotted by using map scales. This is helpful in figuring out how to get from one area to another, especially if one travels or works in a job that requires such knowledge.Map scale on a topographic map = 1:1000000
length between two points = 10cm
aerial distance = x

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.

A lake that has been affected by acid rain can have a ph of 4. so the lake is 10,000 times acidic than seawater
Seawater has a pH of 8, so there's a difference of 4 pH units, so there's a difference in hydrogen ion concentration of 10^4.
here Acid rain is rain or any other form of precipitation that is unusually acidic, meaning that it has elevated levels of hydrogen ions. Most water, including drinking water, has a neutral pH that exists between 6.5 and 8.5, but acid rain has a pH level lower than this and ranges from 4–5 on averageAcid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air.
