Hello!! All three of these are correct except for the third one - archaeologists have discovered that it was destroyed by a massive earthquake. They think it was a volcanic explosion that destroyed the country and island of Crete. Have a great night!!
Answer:
how did the native americans in the pacific northwest adapt to their environment? the native americans in the pacific northwest adapted to their environment by making things out of wood. they depended on the fish, wildlife, and plants instead of farming.The Native Americans used natural resources in every aspect of their lives. They used animal skins (deerskin) as clothing. Shelter was made from the material around them (saplings, leaves, small branches, animal fur). Native peoples of the past farmed, hunted, and fished.The findings conclusively demonstrate that Native Americans in eastern North America impacted their environment well before the arrival of Europeans. Through their agricultural practices, Native Americans increased soil erosion and sediment yields to the Delaware River basin."Indians cultivated and developed many plants that are very important in the world today. Some of them are white and sweet potatoes, corn, beans, tobacco, chocolate, peanuts, cotton, rubber and gum. Plants were also used for dyes, medicines, soap, clothes, shelters and baskets.
Answer:
Ridge and valley landscapes are created by the<u> tectonic movements of the tectonic plates.</u>
Explanation:
The lithosphere is a rigid outermost shell of the Earth. This lithosphere is broken into<u> tectonic plates.</u> The large scale movements of the tectonic plates result in the formation of topographic features like<u> the mountains, volcanoes, valleys, ridges and oceanic trenches. </u>
Therefore, if the tectonic plates are moving away from each other and create a split, it leads to the formation of a<u> valley</u>. Other environmental factors that can facilitate the formation of a valley are climatic weathering, water, wind erosion etc.
The formation of<u> ridges</u> generally occurs due to tectonic deformation driven by subduction zones, thrust faults, etc. Ridges can also be formed by the tectonic deformation caused by magma present in the deeper layers of the Earth. As, the magma pushes the two plates away, a ridge is formed.
Answer:
The correct answer is extrusion of magma.
Explanation:
Extrusion of magma is not a type of sedimentary rocks, but a type of igneous rock.
<u>Sedimentary rocks</u> are mainly composed of <u>sediments deposited from air or water</u>, while igneous rocks make it from molten magma.
The process of formation of extrusive rocks is carried out when the hot magma coming from inside a volcano, it comes to the surface through cracks, and when it reaches the surface of the earth it cools quickly, hardening and forming this type of rocks
.
It can also happen that on its way out, magma melts other rocks, and when all this cools it forms this new type of rocks.
On the other hand, sedimentary rocks are formed by small particles of minerals or other rocks that go through processes in which a rock is broken, transported by ice, water or wind and after several processes it becomes a new rock.
