Whether a volcano is actually dormant or not, is not actually predictable.

Answers

Wouldn’t it just be A? :))

The action of Jack painting the door has been recently completed. Therefore, option A is correct.

The phrase "has just painted" implies that Jack completed the act of painting the door in the very recent past. The use of "has" indicates the present perfect tense, which suggests a connection between the past action and the present moment.

"Just" emphasizes the immediacy of the action, conveying that Jack finished painting the door only a short time ago.

This construction indicates that the door is now in a freshly painted state. The phrase captures the idea that the act of painting has been recently accomplished, allowing for a clear understanding of the door's current condition.

Therefore, option A is correct.

Answers

Explanation:

Both Jews and Muslims consider Jerusalem to be a sacred city. However, Jerusalem am and the wider Palestine region has been conquered numerous times by foreign powers.

At various times in history, it has been ruled by Romans, Egyptians, Byzantines, the Abbasid, Seljuk, Ottomans, and the British Empire.

The Jews consider the region as The holy land where their forefathers lived. Muslims only consider Palestine as the third-holiest place in the religion while for Jews it is not just about religion but about an ancestral home that they lost.

In the last 1500 years the area has mostly been ruled by Muslims and before that, only for a short period was it controlled by Jews themselves.

Yet, after the British Empire disintegrated, both Muslims and Jews laid claim to the land. Jews saw it as an opportunity to go back to their homeland, while Muslims believed that they could make their own country, free of foreign control.

Herein lies the problem, for both communities it is not just about religion but a matter of survival.

Below the mask of religion, there are obvious undertones to nationalism, survival, and to a lesser extent racial superiority from both sides.

Matters have only worsened due to Arabs losing two wars with Israel, which led to Israel annexing Egyptian, Syrian and Jordanian territory.

How do you convince two people to give up a piece of land which both belief is not only integral to their religion but to their survival as a nation?

Explain how caves, arches, stacks and stumps are formed

Answers

Answer:

That's the answer thank you and your welcome

Answer:Weathering and erosion can form caves, arches, stacks, and stumps along a cliff's edge. Caves form when waves smash into cracks in the cliff face.

The stack will be attacked from the bottom, similar to how a wave-cut notch is formed. This weakens the structure, causing it to collapse and form a stump.

If the distance between two places is 1000m and the height between them is 100 m, what is the gradient ?

Answers

The gradient between the two places is 0.1

Gradient (slope) is the ratio of change in vertical distance to change in horizontal distance. It is given by:

Gradient = vertical distance / horizontal distance

Given that the horizontal distance is 1000m and vertical distance (height) is 100 m, hence:

Gradient = vertical distance / horizontal distance

Gradient = 100 m / 1000 m

Gradient = 0.1

The gradient between the two places is 0.1
