(just a quick science question, pls correct my answer if im wrong..)

Which of the following statements is true
A.) there is more water on earth now than there was millions of years ago ****
B.) there is less water on earth now than there was millions of years ago
C.) there is no way to tell how much water was on earth millions of years ago
D.) there is the same amount of water on earth now as there were millions of years ago

D. the real issues is what does "millions of years ago". Early in Earth's life, there was much more water, but without an atmosphere, estimates are that a quarter of all the water left Earth into space. But that was about 4 billion years ago (4000 million years ago). After the atmosphere formed, the heat was contained, and warm water recondensed, and fell back to Earth. So in recent times, say a few million years, the amount of water on Earth has stayed essentially the same.

To determine which statement is true regarding the amount of water on Earth now compared to millions of years ago, we can analyze the water cycle and geological changes over time.

Statement A suggests that there is more water on Earth now than there was millions of years ago. This statement is incorrect. The total amount of water on Earth remains relatively constant due to the continuous water cycle. Water evaporates from the surface, forms clouds, falls as precipitation, and eventually makes its way back to the oceans, rivers, and lakes.

Statement B proposes that there is less water on Earth now than there was millions of years ago. This statement is also incorrect because the water cycle ensures that the total amount of water on Earth remains relatively constant.

Statement C suggests that there is no way to determine how much water was on Earth millions of years ago. This statement is partially correct. While it is difficult to precisely quantify the amount of water from millions of years ago, scientists can make reasonable estimations based on geological evidence, such as sediment deposits and the presence of ancient lakes and oceans.

Statement D states that there is the same amount of water on Earth now as there were millions of years ago. This statement is the most accurate. While there may be slight variations due to volcanic activity or other geological processes, overall, the total amount of water on Earth has remained relatively constant across millions of years.

Therefore, the correct statement is D: There is the same amount of water on Earth now as there were millions of years ago.
