Answer:
volcanoes
Explanation:
As the plates moved apart, excessive eruptions of lava constructed volcanoes and filled rift valleys. Subsequent movement rifted these later lava fields, causing long, linear valleys bounded by parallel faults. The divergence of the ridge started in the north about 150 million years ago and 90 million years ago in the south. These movements continue today, accompanied by earthquakes, reactivation of old volcanoes, and creation of new ones. I hope this helps!!
Answer: He found a rock, and the crystals inside are minerals.
Options:
- He found a rock, and the crystals inside are minerals.
-
He found a mineral, and the crystals inside are rocks.
- He found a rock, and the crystals inside are rocks, too.
-
He found a mineral, and the crystals inside are made of dirt.
Explanation:
A rock differs from a mineral. While they are both solid, a mineral has a crystalline structure while a rock does not have a specific structure. Rocks are made up of different mineral structures and that is what Joseph discovered on dropping the rock, one of the component minerals in the rock. For example, a type of rock, slate may consist of feldspar, quartz among many other minerals.
Answer:
Option D, Oil forms because of geologic heat and pressure and can be found around the world in varying amounts.
Explanation:
Oil existing beneath the earth surface is primarily due to the deposition of organic matter millions of years ago with in the deep earth crust.
This deposition was uneven. With the temperature and pressure, the organic matter converted into fossil fuel (oil, coal etc.)
Hence, option D is correct
