In the early 1900s, a scientist named Alfred Wegener studied geology and meteorology. He noticed that northwestern Europe, which generally has a cool climate, contained a type of coal deposits that could only be formed in hot, wet climates. He also knew that paleontologists, who study fossil records, had found fossils of similar extinct reptiles in Africa and South America, even though those reptiles would not have been able to swim across the ocean that now separates Africa and South America.

Question 2
Scientific evidence indicates that fossil fuels (oil, coal, and natural gas) form in areas where plates are colliding and tiny, dead organisms can get buried deep in the crust as those plates collide. This means scientists expect to find fossil fuel deposits near the edges of continents. However, large fossil fuel deposits are also found in deserts and even in arctic areas where conditions are currently not suitable for fossil fuels to form.
9. Put the following steps in chronological order (first at the top to last at the bottom) to communicate a logical explanation for how the above situation can be caused.

Arrange responses in the correct order to answer the question. Select a response, navigate to the desired position and insert response at that position. Responses can be selected and inserted using the space bar, enter key, left mouse button or touchpad. Responses can be moved using the up and down arrow keys or by dragging with a mouse.
Due to the movement of plates, the rock containing these fossil fuels can be moved thousands of miles and can end up in deserts or arctic regions.
Over long periods of time, high heat and pressure rearrange the molecules of this organic matter to form fossil fuels.
When plates collide, organic matter from tiny, dead organisms gets buried when one plate drops b
Plate tectonics
1. Over long periods of time, high heat and pressure rearrange the molecules of this organic matter to form fossil fuels.
2. When plates collide, organic matter from tiny, dead organisms gets buried when one plate drops below the other.
3. Due to the movement of plates, the rock containing these fossil fuels can be moved thousands of miles and can end up in deserts or arctic regions.
Many areas of the world rely on aquifers for water for household, industrial, and agricultural use. Experts predict that some of these aquifers are at risk of running dry.
