How does earth continents different positions than today?
Scientists believe that Earth's continents were once connected in a single landmass called Pangaea, which began breaking apart about 200 million years ago. Over time, the movement of tectonic plates has caused the continents to drift to their current positions. This process, known as continental drift, is ongoing and continues to reshape the Earth's surface.
Is Mexico considered a continent?
There are a city, state and country named Mexico:
How many days during the year is the Sun directly overhead in the continental US?
The Sun is directly overhead in the continental US on two specific days each year, typically around late June and late December. These correspond to the summer and winter solstices respectively.
The term for a large landmass that is smaller than a continent and separated by physical barriers is "subcontinent." Subcontinents are distinct regions that have their own unique geological and geographical characteristics.
What is the largest continent in the world and where is it?
Asia is the largest continent in the world. It is located in the Eastern and Northern Hemispheres and covers an area of about 44.58 million square kilometers.
What continent is located in the tropics and south temperate zones?
South America spans across the tropics and the south temperate zones. The continent crosses the equator and extends southwards to include regions with temperate climates.
A continent that would never have the sun directly overhead at any time during the year?
Antarctica would never have the sun directly overhead at any time during the year due to its location near the South Pole. The tilt of Earth's axis ensures that the sun never reaches directly overhead in this region.
"30 degrees east longitude" is the description of a line that joins the north and south poles
and crosses territory in Europe, Asia, Africa, and Antarctica.
"150 degrees west longitude" is the description of a line that joins the north and south poles
and crosses territory in North America and Antarctica.
What continent has yielded the largest trove of meteorites?
Antarctica has yielded the largest trove of meteorites due to the ice sheets that preserve and concentrate them. Antarctica's cold, dry conditions help preserve meteorites on the surface where they can be easily collected.
If I remember correctly, it is Antarctica, because in the process of making a model of the earth flat so that it can become a map, the globe is distorted, meaning that some seas and continents look bigger than they really are, like Greenland.
How big does an area of land have to be to be considered a continent?
Continents are generally identified by convention rather than any strict criteria.
Conventionally, "continents are understood to be large, continuous, discrete masses of land, ideally separated by expanses of water."[1] Many of the seven most commonly recognized continents identified by convention are not discrete landmasses separated by water. The criterion "large" leads to arbitrary classification: Greenland, with a surface area of 2,166,086 square kilometres (836,330 sq mi) is considered the world's largest island, while Australia, at 7,617,930 square kilometres (2,941,300 sq mi) is deemed to be a continent. Likewise, the ideal criterion that each be a continuous landmass is often disregarded by the inclusion of the continental shelf and oceanic islands, and contradicted by classifying North and South America as two continents; and/or Asia, Europe and Africa as three continents, with no natural separation by water. This anomaly reaches its extreme if the continuous land mass of Europe and Asia is considered to constitute two continents. The Earth's major landmasses are washed upon by a single, continuous world ocean, which is divided into a number of principal oceanic components by the continents and various geographic criteria.[2][3]

What is the force that caused the movement of continents from one supercontinent to the other?
The force responsible for the movement of continents is known as plate tectonics. This is driven by the movement of molten rock beneath Earth's surface, which creates convection currents that push and pull the tectonic plates, causing them to move and shift over time.
How do continents affect surface currents?
Continents can block the flow of surface currents, creating barriers that deflect the currents in different directions. They can also influence the direction and speed of currents by shaping the coastlines and creating deep ocean basins that can channel currents. Additionally, continents can impact the distribution of heat and moisture, which can affect the intensity and direction of surface currents.
Theory of plate tectonics explains how forces deep within earth can cause ocean floors to spread and continents to move
Do some scientists think the continents once formed a single landmass?
Yes, the theory of continental drift suggests that the Earth's continents were once joined together in a single landmass called Pangaea. This theory is supported by evidence such as the matching shapes of continents, distribution of fossils, and geological similarities across continents.
