Continent
jig-saw shapes when puzzled and combined together, formed one big continent -
Pangea, and was separated by drifts.
Fossil
comparisons of different species were discovered into two different, separated
continents in which when you combine them, they were one in the past.
Seismic,
volcanic, and geothermal activity are found along imagined plate
boundaries.
Plates
were actually rubbing against each other as evidence is seen on the formed
mountain ranges.

Paleomagnetism,
magnetic field placement in the layers of the rock are present.</span>
Answer:
There should be only one manipulated variable within a scientific experiment so that the experimenter can be certain it is this variable which causes a pattern in the resultant data, if any exists at all. ... A variable within a scientific experiment is something that is changed
Explanation:
Answer:
The answer is the Earth is tilted as the Earth makes its journey for the year around the Sun.
In general the earth is tilted at angle of 23.5 degrees from vertical axis. So that the Earth always pointing to one side as it revolves around the Sun. This causes varying amounts of Sun light around the Earth during the years gives us seasons.
So here we conclude that the axis of the Earth is most important thing, why the seasons occur.
Tilt:
Whenever the Earth lean towards the Sun, summer season occurs and lean away from the Sun winter season occurs. In between these two spring and Autumn occurs.
When a volcano makes the news for erupting, you’ll often hear mention of other kinds of volcanoes that are dormant or extinct. But what do those terms mean, exactly, and how do scientists figure that out?
First, a little bit about how volcanoes work: Magma collects in reservoirs beneath the earth’s surface, and as it accumulates, pressure in the chamber increases; if it gets high enough, the rocks over it will break, and an eruption will ensue. The silica content of the magma determines what kind of volcano you’ll have. Low silica magma makes shield volcanoes, like Kīlauea on Hawaii’s big island, and cinder cones, like Mexico’s Paricutín, which have lava that flows easily, like molasses. High silica magma creates stratovolcanoes, like Mount St. Helens in Washington, and calderas like the one under Yellowstone National Park, which have lava that is more viscous and flows like taffy.
