Answer:

Geologic time uses the layers of rock to describe the relationships of events and their sequence in chronological order over the history of Earth. The layering is a result of the buildup of tiny bits of rock, sediment, or lava cooling at the surface over many years. Think of it like a stack of pancakes—the bottom layer is the one that was placed first and therefore is the oldest. The sediments that create the layers of Earth are stacked one on top of the other.

Answer:

I will!

Explanation:

to determine the related age of different rocks geologists start with the assumption that unless something has happened in the sequence of sedimentary rock layers the newer Rock layers will be on top of the older ones this is called the rule of superposition with absolute age dating you get a real age and actual years

According to the pressure-flow hypothesis, what mechanism causes the movement of phloem sap from sources to sink tissues? See Se
Vaselesa [24]

Answer:

D) Pressure potential differences between source and sink

Explanation:

high turgor pressure causes the movement of   phloem sap from source to sink, Sap moves through phloem via translocation, the transport of dissolved materials in a plant. Unlike the xylem, which can only carry water upward, phloem carries sap upward and downward, from sugar sources to sugar sinks.

Match the rocks with the material they are made of. igneous rocks /sedimentary rocks /metamorphic rocks
Vlad1618 [11]

The answers would be:

Igneous Rocks - They are made from hot magma.

Sedimentary Rocks - They are made from weathered pieces of rock.

Metamorphic Rocks - They are rocks, small or large which reformed due to high temperature.

If you'd like to know more, read on:

Igneous rocks are formed when hot magma is cooled and then it hardens into a rock. The word igneous comes from the word, "ignis" which means "of fire. They can be formed beneath the Earth or on the surface.

Sedimentary rocks are formed from weathered pieces of rock. These pieces are called <u>sediments</u>. They can also be made out of other material. When these sediments settle, it continues to do so until so much sediment accumulate and they start to press down on each other. The sediments then start to go through compaction and sedimentation which for a sedimentary rock.

Metamorphic rocks form under heat and pressure. They are squeezed and shaped and go through <u>metamorphosis </u>or go through change. A metamorphic rock can be formed from any other type of rock as long as it goes through changes due to intense pressure and/or heat.
