The direction they're headed towards is the direction they're walking
It is a true statement. We do this with tomatato plants all the time. If you have ever looked closely at a tomatato plant you will notice tiny hairs on it, each hair can grow a new root system. So I cut it off then place it in a grow seed tray with some support and it grows a whole new plant. You do have to remove the leaves except the very top ones say 15-20 leaves should be left on the plant you want a bare stem up to that. Also works witha variety of ivy plants.
Cohesion known as water attraction to other water molecules is one of the major properties of water. liquid water has surface tension. this allows for insects such as water striders to walk on water. question number 3 the answer is because ice is less dense then liquid water because the water molecules for a new large structure as they cool down. of course Lakes freeze a course from top down even though the coldest areas are at the bottom. cold water begins to rises when it begins to freeze it accumulates at the top with a sheet of ice. the ice provides some insulation for the water below so that there is typically a significant portion of water under the ice sheet unless it's extraordinary really cold for a very very very very long time. if a lake froze from the bottom up they would more than likely freeze completely
Changing from a gas to a liquid is called <span>condensation.</span>
Answer:
The first principle you need to understand about geologic time is that the laws of nature are always the same. This means that the laws describing how things work are the same today as they were billions of years ago. For example, water freezes at 0°C. This law has always been true and always will be true. Knowing the natural laws helps you think about Earth’s past, because it gives you clues about how things happened very long ago. It means that we can use present-day processes to interpret the past. Imagine you find fossils of sea animals in a rock. The laws of nature say that sea animals must live in the sea. That law has never changed, so the rock must have formed near the sea. The rock may be millions of years old, but the fossils in it are a clue for us today about how it formed.
Now imagine that you find that same rock with fossils of a sea animal in a place that is very dry and nowhere near the sea. How could that be? Remember that the laws of nature never change. Therefore, the fossil means that the rock definitely formed by the sea. This tells you that even though the area is now dry, it must have once been underwater. Clues like this have helped scientists learn that Earth’s surface features have changed many times. Spots that were once covered by warm seas may now be cool and dry. Places that now have tall mountains may have once been low, flat ground. These kinds of changes take place over many millions of years, but they are still slowly going on today. The place where you live right now may look very different in the far future.
