Plate boundaries are not always the same as the edges of continents. While some plate boundaries do align with the edges of continents, such as convergent boundaries where plates collide, others may run through the middle of continents or diverge away from them. The relationship between plate boundaries and the edges of continents depends on the tectonic setting in that specific region.
The lines that measure east and west on the globe are called longitude lines or meridians. The prime meridian, located at 0 degrees, divides the Earth into Eastern and Western Hemispheres. Longitude lines run vertically from the North Pole to the South Pole.
The lines on a globe refer to latitude and longitude lines that help locate points on Earth's surface. Latitude lines run east-west and measure a point's distance north or south of the equator, while longitude lines run north-south and measure a point's distance east or west of the Prime Meridian. These lines intersect at specific points to create a grid system used for navigation and mapping.
This is a run-on sentence because two independent clauses ("By the 1970s scientists have accepted the idea of moving continents" and "Today geologists refer to this movement as plate tectonics") are connected without proper punctuation or conjunction. To correct it, you could separate the clauses into two sentences or use a semicolon to connect them.
No, the Earth will not run out of oxygen in the future. Oxygen is constantly being produced by plants through photosynthesis, ensuring a continuous supply for living organisms.
