The evidences that support the continental drift theory are the continents fit together like puzzle pieces, layers of rock match in continents across the oceans, and fossils of the same animal species have been found on different continents.

The theory known as continental drift proposes that throughout the course of geologic time, the Earth's continents have moved in relation to one another, giving them the appearance of having "drifted" across the ocean bed. Alfred Wegener proposed the idea of continental drift in 1912, and it asserts that at one point in time, all of the continents were united together as one big body of land.

Subsequently, the land mass began to split out and drift into their current positions. Pangea is the term that Wegener gave to the supercontinent that existed before all of the continents became separated from one another. The fit of the continents, the distribution of ancient fossils, rocks, and mountain ranges, and the positions of past climate zones were some of the pieces of evidence that supported the theory that continental drift occurred.

Isostatic rebound is the rising of the Earth's crust after being depressed by the weight of an ice sheet. This process is still occurring in several regions of North America, particularly Canada, since the ice sheets melted.

Isostatic rebound is a geological process that occurs when the Earth's crust rises in response to the removal of a heavy load, such as an ice sheet. The weight of the ice sheet had depressed the crust, and as it melts, the crust is slowly rising back up to its original position. This process is still taking place in various parts of North America, particularly in Canada, and it can continue for thousands of years. As the land rises, the coastline can change and new landforms can emerge. In some areas, this process has caused a rise in sea level due to the land rising faster than the ocean can fill in the space.

Explanation:

The time period did agriculturists begin to diversify beyond labor-intensive cotton and tobacco industries is during the Green Revolution (1950s)

Give a brief about The Green Revolution,

The Green Revolution, often referred to as the Third Agricultural Revolution, was a time of technological transfer activities that resulted in significantly higher crop yields and agricultural productivity. After World War II, these innovations in agriculture started in industrialized nations and expanded throughout the world until the late 1980s. [3] In the late 1960s, farmers started implementing new technologies like high-yielding cereal varieties, particularly dwarf wheat and rice, as well as the widespread use of chemical fertilisers (to produce their high yields, the new seeds require much more fertiliser than traditional varieties[4]), pesticides, and controlled irrigation. Newer cultivating techniques, such mechanisation, were also adopted in agriculture. Frequently, a set of practises designed to replace conventional agricultural technology was introduced along with these modifications.

What is landscape?

A landscape is an area with various forms of the earth's surface, both in the form of land and water.

What is a landform?

Landforms are features on the Earth's surface that make up the terrain, such as mountains, valleys, plains, or plateaux. They also include coastal features, such as peninsulas or bays, and underwater features, such as ocean basins and mid-ocean ridges.

What is the difference between landscape and landform?

A landscape is a combination of landforms (landform). Landforms are single features, such as a hill or a river valley.

The continent of Australia can be divided into five main landscape areas as follows:

1. western Plato

At first, the West Plato was a very broad plateau then experienced erosion. The area consists of the Hammersley Plateau, Kimberly Plateau, Arnhem Plateau, Macdonnell Plateau, and Musgrave Plateau.

2. Central Lowlands

This area is formed from sediment and stretches from the north coast of the Gulf of Carpentaria to the south on the lowlands of the Murray and Darling Rivers. In this area, there are the Carpentaria basin (north) and Lake Eyre basin (south).

3. Eastern Highlands

This area is known as the Great Separating Mountains. The plateau was formed by old, eroded mountains and stretches from the Cape York Peninsula south towards Tasmania. Ranges include the Blue Mountains west of Sydney and the Snowy Mountains along the state borders of New South Wales and Victoria.

4. West Coast Plains

This plain was formed by rock faults along the west coast of the Australian Continent. Rock faults on a narrow beach have been pressed down to form a coastal plain.

5. East Coast Plains

Rock fractures in the Eastern Highlands along the east coast give rise to a narrow coastal lowland. The narrow coastal strip is made up of river valleys and hills. Several short rivers including the Burdekin, Fitzrog, and Hunter Rivers are important for agriculture and people.

Answer:

The factor that is least likely to influence the size of a wave as it moves across the ocean is the temperature of the ocean water. The size of a wave is mainly influenced by the wind speed, wind duration, and the fetch (the distance over which the wind blows without being obstructed).

Explanation:

water cycle have different water residence times. Residence time is defined as the amount of water in a reservoir divided by either the rate of addition of water to the reservoir or the rate of loss from it. The oceans have a water residence time of 3,000 to 3,230 years.

The amount of time a fluid parcel has spent inside a control volume is known as its residence time (e.g.: a chemical reactor, a lake, a human body). In order to quantify the residence time of a group of parcels, either the frequency distribution of the residence time within the group, known as the residence time distribution (RTD), or the average residence time, known as the mean residence time, must be considered.

In chemistry, particularly in pharmacology and environmental science, residence time is crucial. In supply chain management and queueing theory, where the material that flows is typically discrete instead of continuous, lead time or waiting time, respectively, plays a crucial role.

When convergent boundaries interact, they can cause the collision and eventual merging of the two tectonic plates. This can lead to the creation of a mountain range, volcanic activity, and earthquakes.

Explanation:

Four ways the Earth heats the atmosphere include :

The Earth's surface emits longwave radiation, which is absorbed by the lower atmosphere. This process warms the air and contributes to the overall temperature of the atmosphere. As air near the Earth's surface warms, it rises and is replaced by cooler air. This movement of air is known as convection.

Advection refers to the horizontal movement of air. As air moves from one place to another, it can carry heat from the Earth's surface to other parts of the atmosphere. Conduction occurs as heat is transferred from the Earth's surface to the air immediately above it.

a) Transpiration rates would be lower than precipitation rates of water over oceans

b) Runoff rates would be higher

Streamflow speeds would've been lower than evaporation of water over seas, and transpiration rates would've been lower than precipitation rates. The ocean would be absorbing more liquid than it is loosing through evaporation, leading the evapotranspiration to be higher than the runoff rates, if the mass balance of the planet's water were rising in the seas and dropping on land. On the other side, the ground would be losing more liquid via transpiration than it is obtaining through precipitation, resulting in a difference between the rates of precipitation and transpiration over land. The water cycle would go out of balance as a result, with the ocean acquiring more liquid and the country losing more water.

If the mass balance of global water was rising in the oceans and falling on land, two processes in the water cycle that are likely to be out of balance are "evaporation rates of water over oceans" and "precipitation rates of water over land".

When the mass balance of global water is rising in the oceans and falling on land, the ocean levels will rise and there will be an increase in the evaporation rates of water over oceans.

This means that more water will be transformed from liquid to vapor form, increasing the amount of water vapor in the atmosphere.

On the other hand, the falling water levels on land would result in lower precipitation rates over land.

Precipitation is the process by which water vapor in the atmosphere condenses into liquid form and falls to the ground as rain, snow, or hail. If there is less water vapor in the atmosphere over land, there will be a decrease in the amount of precipitation over land, leading to drier conditions.

Human actions have had a significant impact on the Earth's climate over time, causing significant changes in temperature, precipitation patterns, and sea levels.

These detrimental effects are primarily caused by greenhouse gas emissions, deforestation, alteration of land use, and the seas. As a result of the planet's temperature rising brought on primarily by the burning of fossil fuels, significant amounts of carbon dioxide, methane, and other greenhouse gases have been released into the atmosphere. This has led to an increase in the frequency and severity of heat waves, droughts, and storms. Deforestation has also increased atmospheric levels of greenhouse gases by decreasing the amount of carbon dioxide that trees are able to absorb. This is due to the clearance of forests for agriculture and urban development.

By altering the land surface, land-use changes like urbanization, dam construction, and mining have also had an effect on the Earth's climate. Additionally, due to human activities like waste disposal and the combustion of fossil fuels, the oceans have become more acidic, harming marine life and lowering their ability to absorb carbon dioxide. Reduced greenhouse gas emissions and the adoption of sustainable practices are essential for addressing these problems and mitigating the effects of human activity on the climate.

Answer:

"chiasmata."

Explanation:

Chiasmata are the regions on a chromosome where non-sister chromatids exchange genetic material during cell division. This process, called crossing over, leads to the formation of new combinations of genes and is an important mechanism for generating genetic diversity. Chiasmata play a crucial role in ensuring the proper segregation of chromosomes during meiosis, the type of cell division that produces gametes for sexual reproduction.

Regions where nonsister chromatids cross over are called "chiasmata". Chiasmata are the physical points where two homologous chromosomes exchange genetic material during meiosis.

During meiosis, homologous chromosomes pair up and exchange genetic material, which creates new combinations of genetic information in the resulting cells.

Chiasmata are the result of a process called "crossing over", which occurs when the nonsister chromatids of two homologous chromosomes exchange genetic material.

This process results in the creation of new combinations of genetic information, which can lead to genetic diversity.

The formation of chiasmata is an important step in the process of meiosis and is essential for the creation of genetic diversity. This diversity is important for the survival of a species, as it allows populations to adapt to changing environments and resist diseases.

Mountains, hills, and woods tend to delay or channel wind over land, whereas the ocean offers a smooth surface on which wind can travel faster without interruption.

Simply, wind is air in motion. When discussing the wind in meteorology, we frequently focus on its horizontal speed and direction. For instance, if you see a forecast of a west breeze at 15 mph, it signifies that the westward-moving horizontal winds will also be moving at that pace. The pressure gradient and wind speed are directly inversely related, which means that as the pressure gradient in other words, change in pressure grows, the wind speed at that place similarly increases. Isobars, or lines of equal pressure, represent high and low pressure. The force that the air exerts on objects allows us to measure the speed of the air even when we cannot actually see it moving. We use an anemometer to determine the wind's speed and a wind vane to show the wind's direction. However, we can still establish the direction even without those tools.
