According to Hess's theory, what might happen if the magma under a mid-ocean ridge cools?

•The magnetic stripes might reverse direction.

•The deep-ocean trench might become deeper.

•The crust at the ridge might form more quickly.

•The plates on either side of the ridge might stop moving,

The plates on either side of the ridge might stop moving

Explanation:

Rear Admiral Harry Hammond Hess proposed a theory that was named after him, he stated that oceans rises from their centres, with molten material (basalt) moving up from the Earth's mantle along the mid ocean ridges. The purpose of this theory is to give explanation to how the continents could actually drift, and the planet on either side of the rigde might stop moving.

Most noble for his theories on sea floor spreading, especially the correlation between island arcs, seafloor gravity anomalies, and serpentinized peridotite, proposing that the convection of the Earth's mantle was the driving force behind this process.

The correct answer is D)

The plates on either side fo the ridge might stop moving.

Explanation:

Harold Hammond Hess a US Navy Officer and geologists proposed a theory that the earth beneath the sea was constantly moving and that this was responsible for drifting apart of the continents.

He suggested that during the movement which is caused by the downward action of gravity on the tectonic plates, on either side of ridges found in the middle of the ocean, molten magma (which is simply rock superheated by the core of the earth until it becomes liquid) finds its way through cracks.

The termination of movement on either side is held as a probable event because, though molten magma contributes to the tectonic shifts, they are not solely responsible.

one thousand and one nights, also known as arabian nights is a collection of stories whose basic structure is that of embedded narrative. this technique refers to a main story which works as the common frame - or framing narrative - for the other stories, and then this series of stories which are connected to the main one. this technique can also be referred to as a story within a story. the stories stem from the original tale, some begin and end on their own, some are connected to the previous or following one, by means of questions that are answered in the subsequent tale, or characters which reappear.

the sentence that best describes the tone of the passage from the radio broadcast compared to the passage from the book is b. the radio broadcast has a more surprised tone.

consider the text evidence: in the passage from the book, the description is more matter-of-fact. it is simply describing the things resembling little grey snakes, but there is no urgency in the description. on the other hand, in the passage from the radio broadcast, there is definetely urgency (you can tell from the expression used, "good heavens", which clearly indicates surprise.)
